Committee TR-8 develops and maintainsstandards for private radio communicationssystems and equipment for both voice and dataapplications. TR-8 addresses all technicalmatters for systems and services, includingdefinitions, interoperability, compatibility andcompliance requirements. The types of systemsaddressed by these standards include businessand industrial dispatch applications, as well aspublic safety (police, ambulance, fire fighting,etc.) applications.

Committee TR-8 has been thestandards formulation committee forPrivate Land Mobile Radio Systems,

which traditionally has involved frequencymodulated (FM) analog technology. The pastdecade has seen the development of standardsfor digital radio systems of varioustechnologies. This transition has increased thesophistication of radiosystems and, as a result, hasnecessitated an increasedlevel of standardization formany of the components ofthese systems. In addition,as new technologies aredeployed, issues ofcompatibility andinteroperability are of primeimportance. In communica-tions systems for publicsafety and emergencyservices, reliability andinteroperability areespecially important.Officers from various

agencies find they need to communicateamong themselves more frequently. Thecriticalness of these communications alsorequires the avoidance of unwantedinterference. All these requirements havecaused Committee TR-8 to assume a widerscope in the standards being developed.

2002 ActivitiesSeveral key projects have resulted in a highlevel of activity for the TR-8 subcommittees.The National Coordination Committee(NCC), an advisory committee to the FederalCommunications Commission (FCC), hasrequested that TR-8 develop interoperabilitystandards for wideband data systems for the700 MHz frequency band. The time framefor this project has caused some of thesubcommittees to accelerate their activities. Inaddition, new spectrum allocations,combined with requirements for morespectrally efficient interoperable communica-tions systems, have resulted in heightenedinterest in developing standards in anexpeditious manner.

TR-8 and its subcommittees met five timesduring the year. The meetings were held inconjunction with the APCO/NASTD/FED

Project 25 meetings. (APCO/NASTD/FEDis a collective group of the Association ofPublic Safety Communications OfficialsInternational, Inc. [APCO]; the Associationfor Telecommunications and TechnologyProfessionals Serving State Government; andfederal government agencies.) In addition,many of the subcommittee working groupsmet throughout the year, either viateleconference or at various locations.Improved working methods using emailreflectors and the migration from distributionof documents in hard copy to soft copy usinga local area network at the meetings for thepast two years have resulted in improvedcommunication and document distribution.

Work continued on Project 25 digital privateradio standards by many of the TR-8subcommittees. This suite of standardscurrently consists of 35 published documentsplus addenda to 10 documents. The majorityof work consisted of upgrading the standardssuite of Telecommunications SystemsBulletins (TSBs) and Interim Standards toANSI/TIA/EIA standards and of publishingaddenda to existing standards. Within theyear, four documents were upgraded andpublished as ANSI/TIA/EIA standards. Inaddition, two standards were revised and twoTSBs and five addenda were published. Workalso began on the development of standardsfor a two-slot Time Division Multiple Access(TDMA) system as a part of Phase II ofProject 25. An initial Air Interface PhysicalLayer document has been published.

The ANSI/TIA/EIA-603-B document, LandMobile FM or PM Communication EquipmentMeasurement and Performance Standards, hasbeen updated and published. This latestrevision was the result of the FCC’s addingrequirements for the 700 MHz frequencyband.

Subcommittee TR-8.11, Antennas, has beenworking on revisions to its two existingdocuments: one that replaces TIA/EIA-329-B-1, Minimum Standards for CommunicationAntennas, Part II: Vehicular Antennas formobile antennas, and one that updatesTIA/EIA-329-B Minimum Standards forCommunication Antennas, Part 1: Base StationAntennas. Additional work on standardizedformats for specifying filtering andtransmission components has been initiated.

The establish-ment of the 700MHz frequencybandnecessitated thedevelopment ofdata standards.TR-8 has starteddevelopinginteroperabilitystandards for the wideband data system. Inorder to meet the NCC time schedule ofFebruary 2003, Subcommittee TR-8.5,Signaling and Data Transmission, expeditedits work. Within the year, four TIA standardswere published. In addition, four documentsare in the drafting or ballot process. Work hasalso begun in other subcommittees towardformulating standards for method ofmeasurement and performance requirements.This has resulted in two documents beingballoted.

Work has continued in Subcommittee TR-8.17, Radio Frequency (RF) Exposure,toward the development of guidelinedocuments for compliance with FCCmandated RF exposure limits for mobile,portable and base station equipment. Adocument for the product labeling and usertraining for mobile and portable equipmenthas been drafted and has been approved forpublication as TSB-133, “Private Land

Work is continuing within SubcommitteeTR-8.18, Wireless Systems Interference andCoverage, on issues of interference predictionand spectrum compatibility. TSB-88, WirelessCommunications Systems — Performance inNoise and Interference Limited Situations —Recommended Methods for Technology-Independent Modeling, Simulation, andVerification, is undergoing revision. One ofthe issues addressed in the document upgradeis the interference potential between systemsincorporating some of the newest digitaltechnologies. An addendum to that

document has been published. In addition,the subcommittee has been active inproviding input to the FCC on interferenceprotection issues.

TR-8 has continued to monitor internationalstandards activities through the participationof committee members and TIA staff.Working Group 8.20, InternationalActivities, is focusing on standardsharmonization and spectrum issues.

2002 has been a year of accelerated activitywithin TR-8. The public safety community’sneeds for reliable, interoperablecommunications systems, the authorization ofthe 700 MHz frequency band, and advancesin technology have caused a surge in activity.Despite the uncertain economic climate,interest and activity in the work of TR-8remains high. The coming year is expected tobe one of even more interest and increasedparticipation.

TR-14 isresponsible forstandards andrecommendedpractices relating toterrestrial fixedpoint-to-point radiocommunicationsequipment andsystems (microwaveradio), primarily inthe frequency bandsabove 960 MHz.

Within the TR-14 committeestructure, only SubcommitteeTR-14.7, Structural Standards

for Steel Antenna Towers and AntennaSupporting Structures, was active in 2002.The subcommittee is completing editorialrevisions of the updated “bible” for the towerindustry: ANSI/TIA/EIA-222, StructuralStandards for Steel Antenna Towers andAntenna Support Structures. The currentstandard is the sixth incarnation ofANSI/TIA/EIA-222, 1996 Version F, whichwas reaffirmed in 2001 to preserve the cycleand to allow additional time for thecompletion of its successor. TR-14.7 is closeto unveiling a major expanded revision of thisstructural standard for towers and antennasupport.

It is anticipated that Version G ofANSI/TIA/EIA-222 will be submitted forballoting and comment in the spring of 2003.Final adoption is forecast for late in the thirdquarter of 2003.

For sheer volume of information, the 222-Gstandard will surpass its predecessors by threeor four times, including more than 150 pagesdevoted to state-by-state map graphicsillustrating wind, ice, frost and seismicfactors. The large amount of material

contained in this version will requireelectronic versions to also be made available.All new tower construction and majorrenovations of existing structures mustconform to 222-G after its adoption. Existingtowers will not be affected unless physicalalterations are made or antenna loadingexceeds the original approved design. Whichstandard applies is usually a decision of theengineer of record.

Revision G will contain new material andexpanded content. Comprising 16 chapters, ithas been prepared by eight different taskgroups and covers technical issues such aswind and ice loading, seismic loading, designstresses, safety and climbing, and geotechnicalrequirements.

As an example of changes in the newstandard, there are revisions to geotechnicaldefinitions, such as “normal soil,” fordetermining lateral load capacities, bearingload capacities and resistance to pull-out.“Normal soil,” at this time, is defined as a setof parameters always intended for biddingpurposes. Over the years, this definition hasbecome practice, and in some instancesfoundations were actually installed for it. Thecommittee has eliminated the term and isgoing to give values that are representative ofa soil type, similar to those used in buildingcodes (e.g., values representative of sand, clay,etc.). The committee’s aim is to determinereal-world, conservative values. The intent isto drive purchasers toward the use of ageotechnical report to solve all initialinstallation problems and economics.

Other issues such as safety and climbingrequirements have also been addressed in thelatest version. The committee has beenworking simultaneously on a new gin polestandard (PN 4860, Structural Standards forSteel Gin Poles Used for the Installation of

Antenna Towers and Antenna SupportingStructures). Gin poles are used in towererection and this standard will allow towererectors and designers to merge thesetechnologies to ensure efficiency and safety.

Revision G will be the most sweeping changein the 222 standard since Revision D wasimplemented 20 years ago. The committee’sintent is to create an internationallyrecognized and acceptable standard that canbe implemented beyond the North Americanmarket. The committee believes the standardwill eclipse the state of the art in any other

standard in the world. The standard isincorporated by reference in the InternationalBuilding Code, which means that by defaultit becomes the most widely recognized towerstandard of most countries, states andmunicipalities for their building codes,although there is often a lag of two to threeyears for the local level to catch up.

Committee TR-30 develops standards related tothe functional, electrical and mechanicalcharacteristics of interfaces between DataCircuit-Terminating Equipment (DCE) andData Terminal Equipment (DTE), thetelephone and Voice over Internet Protocol(VoIP) networks and other DCE and FacsimileSystems.

2002 Activities

Once again in 2002 TR-30 focused agood deal of its attention ondeveloping contributions to input to

International Telecommunication Union —Telecommunication Standardization Sector(ITU-T) Study Group (SG) 16 “MultimediaServices, Systems and Terminals.” Particularemphasis was on contributions to thedevelopment of new ITU-TRecommendations for Modem over IP(V.150.0 and V.150.1). TR-30 has had along-standing close relationship with thevarious rapporteurs in ITU-T SG 16 andcontinued this in 2002, with the work onV.MoIP (V. Modem over IP) progressingseamlessly between meetings of TR-30.1 andthe Question 11 rapporteur in SG 16.Extending this relationship, starting in 2003TR-30.5 has invited the experts of Question14 “Facsimile Terminals (Group 3 and Group4)” in SG 16 to work together in progressingV.34 fax capability in Recommendation T.38,

Procedures for Real-Time Group 3 FacsimileCommunication over IP Networks.

Subcommittee TR-30.1, Modems, focusedon its close working arrangement with ITU-TSG 16 and the work already completed onSG 16 Question 11 “Evaluation” to progresswork on the new ITU-T Recommendationsfor MoIP (V.150.0 and V.150.1). Numerouscontributions to this effort were developedand approved by TR-30.1/TR-30 to theITU-T process. This work is continuing withthe development of enhancements to theV.150 family of Recommendations. Inaddition, TR-30.1 continues to be the majorcontributor to refining ITU-TRecommendations V.44, Data CompressionProcedures, V.59, Managed Objects forDiagnostic Information of Public SwitchedTelephone Network Connected V-Series ModemDCEs and the V.9x series (related to digitalmodems).

Growing from its experience with thedevelopment of ITU-T RecommendationV.150.1 (V.MoIP), TR-30.1 is addressing therecently identified issues on Text Telephony(Telecommunications Device for the Deaf[TDD] and teletypewriter [TTY]) over VoIPnetworks. This technology uses the acronymToIP (Text over IP). The committee will beproviding input to this work in ITU-T SG16 and has agreed to develop an interim TIAstandard to address the transport of AFrequency Shift Keyed Modem for Use on thePublic Switched Telephone Network (TIA/EIA-825) over IP, which will address this issue fornetworks in the United States. The difficultiesthat have been experienced with TDDs overIP concern IP networks with various Qualityof Service issues. Packet loss in IP networksand voice compression algorithms have beenseen to limit proper operation of TDDs. Thework in TR-30.1 will be to develop a

standard that will provide reliable transport ofTDDs over various IP networks.

This past year, TR-30.1 approved a newstandard, TIA/EIA-939, Procedures forAutomatic Interworking Between T.30, V.18,V.8bis, V.8, and V.32/Annex A AutomodeModems and V.32bis, V.32, V.22bis, V.22,V.21, V.23, 212-Type and 103-Type Modems,and revised the existing standard TIA/EIA825, A Frequency Shift Keyed Modem for Useon the Public Switched Network.

Subcommittee TR-30.2, DTE-DCEInterfaces and Protocols, withdrew thefollowing standard, since many of itsprovisions were incorporated into ITURecommendations.

• TIA/EIA-615, Data TransmissionSystems and Equipment — SerialAsynchronous Automatic Dialing andControl — Extended Command Syntax

In addition, the following standard wasreaffirmed during 2002:

• TIA/EIA-232 F, Interface BetweenData Terminal Equipment and DataCircuit-Terminating EquipmentEmploying Serial Binary DataInterchange.

Subcommittee TR-30.3, DataCommunications Equipment Evaluation andNetwork Interfaces, continued to focus onnetwork models and equipment evaluationfor data communications equipment in 2002.

TIA-876, Network Access Transmission Modelfor Evaluating xDSL Modem Performance, wasreleased for publication. Service providers,venders and users can use this statisticallyaccurate portrait of the North Americanaccess network and the Network ModelCoverage (NMC) methodology to comparethe performance of different models ormanufacturers of Digital Subscriber Line(DSL) systems (DSLAMs [Digital SubscriberLine Access Multiplexer] and modems) ordifferent technologies. Formal liaison hasbeen established with the Digital SubscriberLine Forum (DSLF), ITU-T SG 15 “Opticaland Other Transport Networks” Question 4“Transceivers for Customer Access and In-premises Phone Line Networking Systems onMetallic Pairs,” and EuropeanTelecommunications Standards Institute(ETSI) TM6 “Transmission andMultiplexing” to develop internationalversions of the standard.

TR-30.3 continued its revision of TSB-38,Test Procedures for Evaluating ModemPerformance. This project involves a majorrevision of the existing document to align itwith today’s technologies and to expand it toinclude MoIP.

Work was started on PN-3-0062 (TIA/EIA-921), Network Model for Evaluating ModemOver Internet Protocol (MoIP) TransmissionPerformance. This project defines the network

In 2002, Subcommittee TR-30.5, FacsimileTerminal Equipment and Systems, focusedon the ITU-T Recommendation T.38,Procedures for real-time Group 3 facsimilecommunication over IP networks. The primaryfocus has been to add V.34 fax capability toT.38. Other aspects for enhancing T.38 arebeing considered (e.g., use of improvedpacket network transport layer protocols,secure facsimile, interoperability withV.MoIP). A number of contributions to ITU-T SG 16 in support of this effort wereapproved through the TR-30.5/TR-30process.

During 2002 TR-30.5 reaffirmed thefollowing standard:

• TIA/EIA-605, Facsimile DCE-DTEPacket Protocol Standard

In addition, TR-30.5 withdrew the followingstandards:

• TIA/EIA-465-A, Group 3 FacsimileApparatus for Document Transmission

• TIA/EIA-466-A, Procedures forDocument Facsimile Transmission

• EIA-497, Facsimile Glossary

• TIA-538, Facsimile Coding Schemesand Coding Control Functions forGroup 4 Facsimile Equipment

Wireless consumer communications devices, such as cordless telephones and Citizens Band (CB)radios, were the core products within Committee TR-32’s purview. The Committee’s work in the pastincluded maintaining standards, recommending new projects and reviewing work programs for newstandards.

2002 Activities

No issues required the work of Committee TR-32 during 2002. Due to decliningparticipation in the work of TR-32, the TIA Technical Committee voted in 2002 toretire TR-32 at the end of 2002 and transfer its cordless telephone-related activities to

TR-41, since cordless telephone manufacturers are active in that committee. In fact, thecoexistence of cordless telephones in the same spectrum as Wireless Local Area Networks(WLANs) was a cordless issue that was teed up for continuing work.

However, the CB equipment standards TR-32 had generated did not fit within TR-41. Thus,after consultation with the remaining CB manufacturers of TIA, a decision was made to havethose few standards withdrawn.

TR-32 had a proud tradition of serving the personal radio equipment market, and some of thatwork will go on in TR-41, but as part of the right-sizing of TIA’s standards program, TR-32retired at the end of 2002.

Committee TR-34 is responsible for standardsand studies related to satellite communicationssystems, including both the space and earthsegments. The committee focuses on standards forspace-borne and terrestrial hardware; interfacesbetween satellite and terrestrial systems; and theefficient use of spectrum and orbital resources,including sharing between satellite andterrestrial services. Active projects range fromstudies on how best to accomplish interservicespectrum sharing to developing standards forachieving interoperability between satellitesystems, as well as among satellite and terrestrialsystems, networks and services.

In addition to developing industrystandards specifically for satellitecommunications equipment, Committee

TR-34 has been working with otherStandards Development Organizations(SDOs) to ensure that the standards itproduces are acceptable for satellite services.In particular, Subcommittee TR-34.1,Communications and Interoperability, has

been working closely with the ATM(Asynchronous Transfer Mode) Forum andthe Internet Engineering Task Force (IETF)to ensure the standards developed by thesebodies take the special requirements ofsatellite communications into consideration.

2002 ActivitiesAs in the previous several years, CommitteeTR-34’s 2002 activities were concentrated intwo major areas: developing standards forsatellite communications systems, with amajor focus on the Internet, ATM andGlobal System for Mobile Communications(GSM) and their seamless operation oversatellite; and developing interference criteriaand interservice frequency-sharingmethodologies. This work is accomplished intwo subcommittees — TR-34.1,Communications and Interoperability, andTR-34.2, Spectrum and Orbit Utilization.

Subcommittee TR-34.1 accomplishes its tasksthrough five Ad Hoc Working Groups, all ofwhich address issues related to theinteroperability of the satellite and terrestrialcomponents of communications systems,centered primarily on existing and futurestandards development, including Internet,ATM and GSM and their seamless operations

over satellitetransmissionspaths andcommon airinterfaces.Currently, theTR-34.1 AdHoc WorkingGroups are

configured as follows:

• Internet Protocols over Satellite

• Common Air Interface for ProcessingSatellites

• IP Multicast over Satellite

• Common Air Interface for SatelliteSystems for Residential Market

• TCP Protocol for the IPSECEnvironment

The output of TR-34.1 generally consists ofTIA Telecommunications Systems Bulletins(TSBs), Interim Standards (ISs) andAmerican National Standards (ANSs).Working groups collaborate, when delegated,with appropriate national or internationalstandards bodies.

Subcommittee TR-34.1 alsocontinued its relationship withthe ATM Forum and was activein the Wireless ATM (WATM)Group of the ATM Forum,working to ensure that ATMstandards consider satelliterequirements. Recently, theWorking Group (WG) onCommon Air Interface: ATMVia Satellite achieved a majormilestone, completing its workon ATM over point-to-pointsatellite links and publishingIS-787, Common ATM Satellite

Interface (CASI) Interoperability Specification,detailing frame format, acquisition andsynchronization procedures, and dynamic andadaptive coding.

The Working Group on Internet Protocolsover Satellite continued its liaison with theIETF Transmission Control Protocol-Satellite(TCP-Sat) WG, with the goal of ensuringthat Internet protocols will not preclude theuse of satellites for Internet access. The TCP-Sat WG’s remaining work has been rolledinto the Performance Implications of LinkCharacteristics (PILC) WG, which hasdeveloped a draft IETF submission on therisks and impacts of TCP spoofing. OtherTR-34.1 Working Groups’ closelycoordinated work with ETSI and the ITUTelecommunication Standardization Sector(ITU-T) extended throughout 2002, a trendthat will be a continuing facet of TR-34.1standards development efforts in subsequentyears.

Subcommittee TR-34.2 and its TIA oversightbodies, the Spectrum and Orbit UtilizationSection (SOUS) and the SatelliteCommunications Division (SCD), haveparticipated in expressing their views to the

Federal Communications Commission (FCC)regarding:

• Revision of Part 15 of the Commission’sRules Regarding Ultra-WidebandTransmissions Systems (ET Docket 98-153) Adopted: February 14, 2002;Released: April 22, 2002.

During 2002, TR-34.2 members andinterested parties in the SCD had extensivediscussions concerning the potential forinterference from Ultra-Wideband (UWB)devices into satellite earth station receiversoperating in the 3.7-4.2 GHz Fixed-SatelliteService (FSS) bands. TR-34 discussions wereignited by the National Telecommunicationsand Information Administration’s (NTIA)report (NTIA Special Publication 01-43,Assessment of Compatibility betweenUltrawideband Devices and Selected FederalSystems, January 2001), which alluded to thepossibility of UWB interference affecting FSSearth stations in the 4 GHz range; the NTIAanalyses used generally accepted sharingcriteria and analysis methodologies that areequally applicable to commercial satellitesystems.

On July 26, 2001, the SCD, with input fromTR-34.2, transmitted a letter to the Secretaryof the FCC urging the commission toconsider the FSS interference issue whendeveloping possible rules and operationalrequirements for the deployment of UWBdevices and to adopt a specific technicalregulatory framework to govern UWB devicesthat protect FSS systems from harmfulinterference.

Following the issuance of the letter regardingUWB, it was decided in the SCD and theSOUS that there were no other requirementsfor TR-34.2 to develop technical standardsand/or studies addressing specific spectrumissues at this time; therefore TR-34.2 wouldstand down from holding quarterly meetingsfor the rest of 2002, until SOUS calls for TR-34.2 to re-activate in order to address a new,specific technical spectrum/standards issue.

Committee TR-41 addresses voluntary standardsfor telecommunications terminal equipment andsystems, specifically those used for voice service,integrated voice and data service, and InternetProtocol (IP) applications. The work involvesdeveloping performance and interface criteriafor equipment, systems and private networks, aswell as the information necessary to ensure theirproper interworking with each other, withpublic networks, with IP telephonyinfrastructures and with carrier-providedprivate-line services. It also includes providinginput on product safety issues, identifyingenvironmental considerations for user premisesequipment and addressing the administrativeaspects of product approval processes. Inaddition, TR-41 develops criteria for preventingharm to the telephone network. These criteriabecome mandatory when adopted by theAdministrative Council for TerminalAttachments (ACTA), www.part68.org.

2002 Activities

Committee TR-41 is dynamic andresurgent in nature, with someprojects concluding and new ones

springing up in their place. It completed theyear with six active subcommittees and 10working groups. One subcommittee wrappedup its work and went into inactive status

during the year. Three working groups weredissolved after completing their tasks, whilefive new working groups were formed. Thesubcommittee leadership remained stable inthe chair position, with one person re-elected.However, there was some turnover in the vicechair positions, with two individualsresigning because of job changes and twoothers elected. The year ended with one vicechair position unfilled. TR-41 meets with itssubcommittees and working groups for aweek four times per year.

TR-41 has continued its leadership role insupporting ACTA by submitting revisedtechnical criteria for the prevention of harmto the network and by providing input onadministrative matters. It has also continuedits leadership in developing Voice overInternet Protocol (VoIP) standards. A reporton this work was very well received at theSignaling for VoIP Summit hosted by theAlliance for Telecommunications IndustrySolutions (ATIS)- and American NationalStandards Institute (ANSI)-accreditedStandards Committee T1, Telecommunica-tions, in August 2002. Another area in whichTR-41 subcommittees have been active isemergency preparedness and support forEmergency 911 (E911) by both multilineterminal systems and VoIP enterprise

networks.

TR-41 enjoys a close liaison withTechnical Subcommittee T1E1,Interfaces, Power & Protection ofNetworks, co-locating three of its fourmeetings in 2002. TR-41 alsomaintains liaison with IndustryCanada’s Terminal Attachment ProgramAdvisory Committee (TAPAC), theEuropean TelecommunicationsStandards Institute’s SpeechTransmission Quality (ETSI STQ)Technical Committee, the InternetEngineering Task Force (IETF) and the

In addition, it provides inputto other international Standards DevelopmentOrganizations (SDOs) such as UnderwritersLaboratories (UL), the Canadian StandardsAssociation (CSA), and Technical Subcom-mittee T1A1, Performance, Reliability, andSignal Processing.

Subcommittee TR-41.1, Multiline TerminalSystems, completed work on the revision ofits Private Branch Exchange (PBX) standardand published the document as TIA-464-C,Requirements for PBX Switching Equipment. Italso succeeded in getting its adoption ofIEC/ISO 11573, Information technology —Telecommunications and information exchangebetween systems — Synchronization methodsand technical requirements for privateIntegrated Services Networks, published asTIA-594-A, Synchronization Methods andTechnical Requirements for Private IntegratedServices Networks. The subcommitteereviewed a number of older documents,deciding to reaffirm three and rescind four.TR-41.1 balloted TIA-689-A, PBX and KTSSupport of Enhanced 911 Emergency ServiceCalling, and expects to publish the reviseddocument early in 2003. François Pinier fromAlcatel was elected to fill the vacant vice chairposition at the November meeting.

Subcommittee TR-41.3, Analog and DigitalWireline Terminals, agreed to takeresponsibility for issues dealing with theRadio Frequency (RF) performance ofcordless telephones that formerly belonged toEngineering Committee TR-32, PersonalRadio Equipment, and the work was assignedto TR-41.3.9. This change was made at thesuggestion of the User Premises EquipmentDivision (UPED), which sponsors both TR-41 and TR-32, since TR-32 has becomeinactive, and cordless telephonemanufacturers participate in the work of TR-41. As a result of this change, TR-41.3

became an advocate for the creation of TIA’snew policy on unlicensed spectrum use.

Although documents are balloted andapproved at the subcommittee level, TR-41.3uses working groups to do their actualdrafting. TR-41.3.1 submitted TIA-777-A,Caller Identity and Visual Message WaitingIndicator Equipment PerformanceRequirements, for industry ballot. It isexpected that TIA-777-A will be publishedearly in 2003 following a default ballot toresolve comments received. The reviseddocument will replace both TIA-716 andTIA-777, which contain Type 1 and Type 2caller identification requirements, respectively.

TR-41.3.3 produced TIA-920, TransmissionRequirements for Wideband Digital WirelineTelephones. TIA-920 complements thenarrowband standard, TIA/EIA-810-A,previously produced by the working group,and completes its assignments. As a result,TR-41.3.3 was dissolved following theNovember meeting.

The former TR-41.3.5 Working Groupdealing with the revision of TIA/EIA-470-B,Telecommunications – Telephone TerminalEquipment – Performance and CompatibilityRequirements for Telephone Sets with LoopSignaling, was split into five new workinggroups (TR-41.3.5, 41.3.6, 41.3.7, 41.3.8,

41.3.9), each aligned with a specific part ofthe revision of this document for analogwireline telephones. The new TR-41.3.5submitted TIA-470.110-C, Handset AcousticPerformance Requirements, for industry ballot.TR-41.3.7 submitted TIA-470.220-C,Alerting Response and Acoustic PerformanceRequirements, for industry ballot. TR-41.3.9submitted TIA-470.310-C, Cordless TelephoneRange Measurement Procedures, for a secondindustry ballot after substantial revisions weremade to resolve comments received on thefirst ballot. TR-41.3.6 is nearing completionof its draft of TIA-470.210-C, Resistance andImpedance Performance Requirements. TR-41.3.8 was established but has not begunactive work on the Network SignalingPerformance Requirements document thatwill become TIA-470.230-C.

TR-41.3.9 was already addressing issuesunique to cordless telephones, and thus theresponsibility for RF performance issues wastransferred from TR-32 and added to theworkplan of TR-41.3.9. A liaison relationshiphas been established with the Institute ofElectrical and Electronics Engineers (IEEE)802.19, Coexistence Technical AdvisoryGroup, to discuss possible ways cordlesstelephones and wireless local area networks

can avoid interfering with each other whenoperating in the frequency bands they share.

Subcommittee TR-41.4, IP TelephonyInfrastructure, reaffirmed Bob Bell of Ciscoas chair and elected Richard Hatherill ofMitel as vice chair at its February meeting.Unfortunately, Hatherill was not able tofulfill his term because of a job change;therefore, Joanne McMillen of Avaya waselected as replacement vice chair at theNovember 2002 meeting. TR-41.4 publishedtwo documents: TIA-912, IP TelephonyEquipment Voice Gateway TransmissionRequirements, and TSB-146, IP TelephonySupport for Emergency Calling Service. Thefast-paced world of IP telephony being whatit is, work has already started on the revisionof both documents.

TR-41.4 also has a project dealing with thesecurity framework for IP telephony. Thesubcommittee made a liaison request to theIETF security sector to consider developing asecurity protocol suite suitable for deviceswith limited resources, such as VoIPtelephones. In the interim, Mitel hasdeveloped a protocol that may be suitable andhas offered to put it in the public domain.The TR-41.4.4 working group, VoIPTerminals, continued work on its revision andupgrade of TIA/EIA/IS-811, Performance andInteroperability Requirements for Voice-over-IP(VoIP) Telephone Terminals. Progress on thework has been somewhat hampered byturnover in participants due to industrychanges.

Subcommittee TR-41.7, Environmental andSafety Considerations, also uses workinggroups to create documents it then ballotsand approves at the subcommittee level. TR-41.7.1 identified an inconsistency betweenthe construction and testing methods forshowing compliance with the overvoltagecriteria in UL-60950, Safety of Information


Technology Equipment. The discrepancy wascommunicated to the UL Standards TechnicalPanel (STP) responsible for UL-60950 withan offer to provide help in resolving it;however, the STP chose not to make anychange in its standard.

The revision of the bonding and groundingstandard that had been made jointly by theformer TR-41.7.2 Working Group and theT1E1.7 Electrical Protection Working Groupwas submitted through the ANSI ballotprocess and published as J-STD-607-A,Commercial Building Grounding (Earthing)and Bonding Requirements forTelecommunications. TR-41.7.3 completed itsrevision and publication of TIA-631-A, RadioFrequency Immunity Requirements, and theworking group was subsequently dissolved.

TR-41.7 decided to undertake a revision ofTIA/EIA-571-A, EnvironmentalConsiderations, and created a new workinggroup, TR-41.7.4 for this purpose. DonMcKinnon of AST Technology Labsproduced a baseline document and agreed toserve as editor and interim chair. TR-41.7also formed an ad hoc group to look intosafety requirements for telecom circuit over-current protectors. A liaison letter has beensent to UL advising it of this activity andencouraging participation, with theexpectation that the outcome of the work willresult in a new UL standard for these devices.This ad hoc group is expected to become anofficial working group in 2003.

Subcommittee TR-41.9, TechnicalRegulatory Considerations, undertook arevision and upgrade to ANS status of thecriteria for prevention of harm to thenetwork. The initial version of these criteriawas published in July 2001 in TIA/EIA/IS-968, Telecommunications — TelephoneTerminal Equipment Technical Requirementsfor Connection of Terminal Equipment to the

Telephone Network, and was required by theFederal Communications Commission (FCC)to be identical to the former FCC Part 68rules. The revision included a relaxation ofthe signal power criteria for 56K modems,inclusion of the criteria for AsynchronousDigital Subscriber Line (ADSL) modems andstutter dial tone detection devices that wereinitially required to be published separately,and extension of the frequency range formetallic signal power criteria to 30 MHz. Thedocument was published as TIA-968-A,Technical Requirements for Connection ofTerminal Equipment to the Telephone Network,and submitted to ACTA for adoption. Arecommendation was also made that ACTAallow an 18-month transition period duringwhich products can be approved either to thenew document or to the TIA/EIA/IS-968 andTIA/EIA/IS-883 documents it replaces.

TR-41.9 has two working groups. TR-41.9.1functions as an extension of TR-41.9 for thepurpose of detailed review of contributionsproposing changes to the harms to thenetwork criteria. A new TR-41.9.2 WorkingGroup, chaired by Greg Slingerland of MitelNetworks, was formed to revise TSB31-B,Part 68 Rationale and MeasurementGuidelines. This effort quickly identifiedissues related to there no longer being a singlePart 68 rules document, or even a singleSDO developing harms to the networkcriteria. At the current time, there are criteriarequiring measurement procedures in Part 68itself, in TIA/EIA/IS-883 and TIA/EIA/IS-968, in TIA-968 A that replaces them, andthe T1E1 document T1.TRQ.6-2001,Technical Requirements for SHDSL, HDSL2,HDSL4 Digital Subscriber Line TerminalEquipment to Prevent Harm to the TelephoneNetwork.

TR-41.9 and T1E1 have agreed to developtwo joint standards. One (designated to be J-STD-068) will contain all the technical


criteria for preventing harms to the networkdeveloped by the two organizations. Theother will provide the correspondingmeasurement procedures for the technicalcriteria described in J-STD-068. Both will bepublished as multi-part documents, with theSDO that has the relevant expertise takingthe lead for its part in both documents.

Subcommittee TR-41.10, Private IntegratedServices Networks, did not meet in 2002. Itwas placed in inactive status at the TR-41meeting held in May 2002.

Subcommittee TR-41.11, AdministrativeRegulatory Considerations, completed andpublished TSB-129-A, U.S. NetworkConnections Regulatory Approval Guide. Thisdocument provides guidance to the regulatoryengineer in obtaining approval for connectingequipment to the telephone network usingeither the Supplier’s Declaration of Confor-mity (SDoC) or the TelecommuicationCertification Body (TCB) process. It replaced

the original TSB-129 document that dealtonly with SDoC and the former Part 68Application Guide that was of some use forthe TCB process.

TSB-129-A was submitted to ACTA with therequest that it be adopted in place of thegroup’s Guidelines and Procedures document.ACTA members agreed the document hadmuch to offer but chose not to adopt itbecause of anticipated difficulties in makingchanges to a procedures document not underits control. An agreement was reached toundertake a joint effort by an ACTA ad hoccommittee and TR-41.9.2 to identify itemsthat could be retained in a revision of TSB-129-A that ACTA could consider endorsing,while removing those items ACTA felt shouldbe more directly under its control. This workwas launched in fourth quarter 2002.

TR-41.11 has also undertaken an effort torevise TSB-168, Labeling Requirements. Thisdocument has been adopted by ACTA to

define thelabelingrequirements forequipmentapproved forconnection to thenetwork. Themain goal of therevision of TSB-168 is to reducethe number ofequipmentclassifications to amore manageablelevel and tofacilitate greaterconsistency intheir use. Therevised documentis expected forballot in firstquarter 2003.

Engineering Committee TR-42 developsvoluntary standards for telecommunicationsinfrastructure (cabling and its pathways andspaces), specifically those used for, but notlimited to, voice, video and data networking.The committee’s standards work coverstelecommunications cabling includingcomponent requirements, field-test andinstallation requirements, cabling distances,telecommunications outlet/connector

configurations, and recommended topologies forcommercial buildings, residential, data centers,industrial environments and between buildingsin a campus environment.

TR-42’s work addresses the design andconstruction of telecommunicationsinfrastructure for commercial

buildings, single-family and multi-dwellingresidential, data centers and industrialenvironments, including customer-ownedoutside plant. Telecommunicationsinfrastructure includes the pathways intowhich telecommunications media are placed,as well as the rooms and areas associated withbuildings and outside plant structures used toterminate cables and to install telecommuni-cations equipment. The standards work alsoapplies to mobile homes, marine construction

and other buildings to the extent practicable.TR-42 additionally formulates positions andproposals for harmonization with otherinternational standards bodies and maintainsan ongoing liaison with applicationdevelopers such as the Institute of Electricaland Electronics Engineers (IEEE), andbuilding cabling designers such as BICSI,which train and certify technicians for designand installation of voice and data.

2002 ActivitiesThe TR-42 Engineering Committee isorganized into nine subcommittees and threeworking groups, each responsible for aspecific area of premises telecommunicationsinfrastructure.

The committee held elections in February2002 for itself and all even-numberedsubcommittees.

Committee TR-42’s efforts covered a broadrange of activities during 2002, includingseveral additions to the TIA/EIA-568-B,Commercial Building TelecommunicationsCabling Standard, series of standards.TIA/EIA-568-B.1, Part 1: GeneralRequirements, which specifies overallrequirements for telecommunications cablingin commercial buildings; TIA/EIA-568-B.2,Balanced Twisted Pair Cabling Components,which specifies detailed requirements forcopper cabling; and TIA/EIA-568-B.3,Optical Fiber Cabling Components Standard,which specifies detailed requirements foroptical fiber cabling were addressed.

The TIA/EIA-568-B series of standardscontinues to recognize both twisted paircopper and optical fiber media and providesguidelines on cable selection and distancelimits. Optical fiber is used principally forbackbone cabling between buildings on acampus or between networking equipment on

different floors of abuilding, but hasbeen gainingrecognition for use inhorizontal cabling. Anew laser-optimizedfiber that supports10 Gb/s datatransmission rates for

distances up to 300 meters using serial datatransmission and cost-effective Vertical CavitySurface Emitting Lasers (VCSELs) has beenadded to the optical fiber-choice selections.

Twisted-pair copper is used primarily forhorizontal distribution between networkingequipment in a telecommunications closetand work area equipment, such as a personalcomputer or telephone. TIA/EIA-568.B.2-1,Addendum 1 — Transmission PerformanceSpecifications for 4-Pair 100 Ohm Category 6Cabling, which became a standard in June2002, extended the bandwidth of coppertwisted-pair to 250 MHz and is envisioned tobe a leader in media choice. This document,also known as the “Category 6” standard,specifies requirements for insertion loss, near-end crosstalk loss, equal level far-endcrosstalk, return loss, propagation delay anddelay skew requirements for 100 Ohm 4-pair

category 6 cabling, cables and connectinghardware. Significant work is also beingrealized with mid-span insertion of power fordata terminal equipment, which will allowdevices to be powered without the need to beplugged into an electrical outlet.

Two standards that have been well acceptedby the telecommunications industry andinternational standards were published thispast year. TIA/EIA-862, Building AutomationSystems Cabling Standard for CommercialBuildings, is companion to the TIA/EIA 568B series of standards, in that they fit within acomplementary infrastructure. Alsocomplementary to all of the TR-42 family ofstandards is TIA/EIA 606-A, AdministrationStandard for Commercial TelecommunicationsInfrastructure, which provides the user of thisdocument with guidelines and choices ofclasses of administration for maintainingtelecommunications infrastructure.

Three new addenda were published toTIA/EIA 570-A, Residential Telecommuni-cations Cabling Standard, by SubcommitteeTR-42.2, Residential TelecommunicationsInfrastructure. This technical work has takenon growing importance as more people takeadvantage of the benefits that can be obtainedin the home, including entertainment in the

home, networking andtelecommuting to the work office.Home networking includesinterconnection of computers,peripheral devices, entertainmentsystems, security systems andcontrol systems. The addendaprovide the missing pieces tocomplete a total home networkingsolution and are now beingincorporated into the next editionof the standard.

Testing Length, Loss and Polarity of OpticalFiber Cabling Systems.

TR-42 will continue to grow in scope anddiversity with a global perspective. At thesubcommittee and working group level, thereis an ongoing technical exchange anddialogue with international experts in thefield of cable, connector and systemperformance and testing, such as JointTechnical Committee (JTC) 1/Subcommittee25, Interconnection of InformationTechnology Equipment, Working Group 3,Customer Premises Cabling. The intent is toensure that the TIA cabling standards are atechnically compatible subset and fullyharmonized with international standards.

In addition, to ensure globalization andinteroperability with other standardsdevelopers and industry groups, TR-42 hasestablished liaisons with the Society of CableTelecommunications Engineers (SCTE),Continental Automated Buildings Association

(CABA) and the Open DeviceNet™ VendorAssociation (ODVA).

Several new standards are under developmentincluding:

• a cabling standard for industrialbuildings, and

• a standard for network distributionnodes (data centers).

The gigabit era has introduced many newchallenges. The communications world is in aperiod of change, and the latest documenta-tion from TR-42, its subcommittees andworking groups is evolving to meet theincreased bandwidth demands of futureapplications. For the end user, it is importantto keep abreast of these changes in technologyto ensure correct decisions on cablinginfrastructure issues.


Committee TR-45 develops performance,compatibility, interoperability and servicestandards for mobile and personal commu-nications systems. These standards pertain to,but are not restricted to, service information,wireless terminal equipment, wireless basestation equipment, wireless switching officeequipment, ancillary apparatus, auxiliaryapplications, internetwork and intersystemoperations and interfaces.

2002 Activities

TR-45 is composed of sixsubcommittees and a number of adhoc groups that focus on particular

aspects of mobile and personal communica-tions systems specifications and standards.

In addition to and in support of standardsdevelopment during 2002, TR-45 wasrepresented at or made significantcontributions to a large number of initiativesand Joint Expert Meetings (JEMs) pivotal tothe telecommunications industry. Amongthese initiatives were meetings held to discusshomeland security, visions beyond ThirdGeneration (3G), core network harmoniza-tion, Mobile Equipment Identification(MEID), Wireless Local Area Network

(WLAN) interworking and security andmore. Three of the top TR-45 activitiesduring 2002 were related to globalpartnerships, 3G technologies and MEID.The anticipated exhaust of 32-bit ESNManufacturer Codes continued to beaddressed by the TR-45 subcommittees’ andad hoc groups’ ongoing work to developstandards for MEID.

Subcommittees TR-45.3 and TR-45.5 bothcontinued to meet all requirements forsubmission to the InternationalTelecommunication Union —Radiocommunication Sector (ITU-R)Working Party (WP) 8F updates to M.1457,Detailed Specifications of the Radio Interfaces ofIMT-2000, regarding the respective IMT-2000 3G technologies, UWC-136 andcdma2000®. In the spirit of globalpartnership, TR-45 continued to work closelywith the Third Generation PartnershipProject 2 (3GPP2), as appropriate, in supportof developing specifications for the end-to-end cdma2000® network.

Moreover, Committee TR-45 and itssubcommittees were instrumental in thepublication of many standards and

TelecommunicationsSystems Bulletins(TSBs) in 2002.Noteworthy are thepublications andactivities of thesubcommittees andad hoc groups asdescribed below.

cdma2000® Packet Data Services. With TR-45.6 meetings co-located with 3GPP2 TSG-P(Technical Specifications Group on PacketData), work continues on the next revision ofthe cdma2000® Wireless IP NetworkStandard, as well as on Lawfully AuthorizedElectronic Surveillance for Packet ModeCommunications.

The TR-45 Ad Hoc Authentication Group(AHAG) continued to review and providefeedback on security- and authentication-related issues. Among the items were ITU-TRecommendations, TR-45 emergencyservices-related work, TR-45 ESN/MEIDproposals, and 3GPP2 TSG-S proposededitorial changes to Enhanced CryptographicAlgorithm (ECA) Rev B. Based on theAHAG’s recommendation, TR-45 plans toballot the next revision of the ECA as a TIAstandard based on the 3GPP2 specificationsthat incorporate AHAG changes. To fosterglobal synergy, the AHAG periodically metjointly with the 3GPP S3 security group, aswell as the 3GPP2 WG4 security group, in2002.

Relative to global number administration ingeneral, and the anticipated exhaust of 32-bitESN Manufacturer Codes specifically, theTR-45 Universal Identity Module/EquipmentSerial Number Ad Hoc Group (UIM/ESNAHG) continued to review various standardsand industry concerns related to ESNs andUIMs. The UIM/ESN AHG providedrecommendations to TR-45 on topics such asUIM ID manufacturer codes, UIMadministration, ESN reclamation, ESN re-use, ESN administration, global numberadministration and MEID guidelines. Goinginto 2003, the UIM/ESN AHG will continueto represent TR-45 relative to global numberadministration, particularly at meetings to beheld between the 3GPP2 and GSM/3GPPcommunity.

The Ad Hoc Group on Lawfully AuthorizedElectronic Surveillance (AHG on LAES)made significant progress on the ANS J-STD-025-A, Lawfully Authorized ElectronicSurveillance. In mid-2002, as a result of therelease of the FCC Order on Remand (FCC02-108, CC Docket 97-213), ANS J-STD-025-A (PN-4464) was taken out ofsuspension and work was completed by theAHG on LAES to prepare for ballot. J-STD-025-A provides the enhancements necessaryto support FCC 99-230l, CC Docket No.97-213, Third Report and Order, and FCC

02-108, CC DocketNo. 97-213, Order onRemand, regardingthe four vacatedpunch list items. AnANS ballot was issuedthat coincided with aCommittee T1 ballot,with plans tocomplete the ballotresolutions in early2003 and recommendfor publication in


March 2003. Regarding ANS J-STD-025-B(PN-4465-RV1), the Stage 1 baseline text wasmade available in late 2002. The AHG onLAES continues development of this latestversion of the LAES standard.

During 2002, a decision was made that theTR-45 Network Reference Model Ad-HocGroup (NAG) would be rendered dormantuntil such time as contributions aresubmitted and there is support to updateTIA/EIA-TSB-100-A, the TR-45 WirelessNetwork Reference Model.

TR-45 looks forward to a productive year forthe publication of telecommunicationsstandards in 2003. The committee willcontinue to address standards for lawfullyauthorized electronic surveillance for packetdata surveillance capabilities, emergencyservices, wireless priority service, numberpooling and number portability, MEID,

enhanced IMT-2000 3G technologies,cdma2000® and potentially new securityservices to support homeland security. Basedon direction from the Technical Committee,cooperative efforts have also begun with3GPP2 to address cdma2000® WLANinteroperability standardization with theInstitute of Electrical and ElectronicsEngineers (IEEE).

cdma2000® has been registered in the United States Patent

and Trademark Office by TIA.

The committee generates documentsthat cover systems engineering for theservice descriptions, network archi-

tectures, and functional and physical aspectsof personal communications for U.S. tele-communications networks. These are appli-cable to both wireless and wireline access andto the networking between systems. Thecommittee also develops positions andtechnical contributions on related subjectsunder consideration in other domestic andinternational standards forums, including theInternational Telecommunication Union —Telecommunication Standardization Sector(ITU-T) and Radiocommunication Sector(ITU-R) Study Groups.

TR-46 additionally maintains a close liaisonwith other TIA engineering committees,particularly Committee TR-41, User PremisesTelephone Equipment Requirements, andCommittee TR-45, Mobile and PersonalCommunications Systems, as well as withexternal standards organizations, includingthe Alliance for Telecommunications IndustrySolutions (ATIS) Committee T1, T1P1-Wireless/Mobile Services and Systems, theInstitute of Electrical and ElectronicsEngineers (IEEE) and the European

Telecommunications Standards Institute(ETSI).

2002 ActivitiesTR-46 continued to contribute to TIAstandards activities on both the national andinternational levels, with direct participationin international standards activities,continued enhancement and development ofthe PCS interference project, and the closerelationship with T1P1 and TR-45 in theenhancement and development of networkinteroperability technology.

At the beginning of 2002, the chair requestedthe participants of TR-46.2, NetworkInterfaces, and TR-46.3, NetworkInteroperability, to evaluate their workprograms moving forward. In July, TR-46.2reported that it had completed the work thathad been assigned and requested that its workprogram be closed and the subcommittee bedisbanded. The TR-46 plenary agreed withthe TR-46.2 recommendation and officiallyapproved its disbandment.

TR-46.3 had been awaiting input from TR-45.2 on cdma2000® to update to J-STD-038Revision B, Network Interworking betweenDCS 1900/GSM and ANSI-41 since thebeginning of 2002. The update on

cdma2000® was received, balloted andapproved as part of the J-STD-038 RevisionB. At the November 2002 meeting of TR-46,it was agreed that TR-46.3 had completed itswork program, and the subcommittee wasdisbanded.

With the successful completion of theirrespective work programs by thesubcommittees of TR-46, it was agreed bythe membership of TR-46 that theEngineering Committee itself should bedisbanded. This recommendation todisband TR-46 by year end 2002 was madeto the TIA Technical Committee andaccepted in September 2002.

The closure of TR-46 marks a milestone inTIA standardization. TR-46 was formed inMay 1993 to develop the necessary standardsto enable the deployment of PCS at the 1900

MHz band. TR-46 was responsible for thedevelopment of the necessary protocols forboth ANSI-41- and GSM based-networksand the services to be supported by bothnetwork types. TR-46 also worked closely

with T1P1 in the development of the PCSradio interfaces in the Joint TechnicalCommittee on Wireless Access. TR-46continued working with T1P1 and TR-45 onstandards and technical reports to assist thewireless industry in the evolution of wirelesstechnologies and the sunsetting of certainJoint Standards developed in 1995 and theincorporation of other Joint Standards intocurrent documents developed by both TR-45and T1P1.

The FO-4 Committee on Fiber Optics isresponsible for the development andmaintenance of fiber optic component andsystem technology standards. These standards areintended to be employed by users and suppliersof fiber optic communications technology topromote compatible and interoperable systemsused to support a wide variety of voice, data,video and telemetry applications for trade andcommerce. To this end, FO-4 works closely withother national and international standardsdevelopment organizations in promotingharmonization and ease of use for worldwidefiber optic technology deployment. FO-4 focusesprimarily on fiber optics standards for:

• Testing methodologies for passive andactive components, subsystems andsystems

• Metrology and calibration

• Interface standards

• Component and system specifications

• Performance and reliability

• System design guides

• Terminology and symbology

The newly created FO-4 Committee isthe result of a restructuring andconsolidation of former

Committee FO-6, Fiber OpticComponents, and Committee FO-2,Optical Communications Systems. Forthe past two years, joint meetings ofCommittees FO-2 and FO-6 have beenheld, and ongoing discussions for over ayear on how to improve and streamlinethe committee’s schedule and workprocesses led to the reorganization. Atthe June 2002 meeting, the JointEngineering Committee unanimouslyapproved merging the two engineering

committees, consolidating somesubcommittees and further consolidatingsome of its working groups. This merger ofthe two committees was approved at theirJune 2002 meeting. New scopes wereprepared for each subcommittee and workinggroup, and the formation of FO-4 wasapproved by the TIA Technical Committee inSeptember 2002.

Committee FO-4 has nine subcommitteesand 11 working groups, which develop fiberoptic component and system standards tomeet the needs of users, suppliers and otherstandards organizations throughout NorthAmerica and the world. The committee meetsformally twice a year and maintains morethan 200 published American NationalStandards related to the testing and specifi-cation of fiber optic components and systems.

2002 OverviewAt the two meetings held in 2002, inaddition to the regular participants from allsubcommittees and working groups, attendeesalso participated from the InternationalElectrotechnical Commission (IEC) TechnicalAdvisory Groups (TAGs) to IEC TechnicalCommittee (TC) 86, Fibre Optics. Also, theAlliance for Telecommunications IndustrySolutions (ATIS) T1X1, Digital Hierarchy

and Synchronization, co-located one of itsmeetings with the FO committees, whichallowed a network operator’s perspective tobe brought into the standards developmentactivity for fiber optics equipment.

The committee took an active interest in theongoing activities of both domestic andinternational standards organizations andcontinued to establish formal liaisons withorganizations having mutual interests. InNorth America, these included ATIS

Committee T1, the Institute of Electrical andElectronics Engineers (IEEE), the InsulatedCable Engineers Association (ICEA), theNational Electronics Manufacturing Initiative(NEMI) and the Institute of Interconnectingand Packaging Electronic Circuits (IPC).

Internationally, the committee developedseveral technical contributions in support ofStudy Group 15 “Optical and OtherTransport Networks” in the InternationalTelecommunication Union — Telecommuni-cation Standardization Sector (ITU-T). Thecommittee also participated in the relevantTAGs of the IEC and the Joint TechnicalCommittee 1 (JTC1) including:

• IEC TC 86 and its subcommittees

• Subcommittee 86A, Fibre and Cables

• Subcommittee 86B, Fibre OpticInterconnecting Devices

• Subcommittee 86C, Fibre OpticSystems and Active Devices

• ISO/IEC JTC1/SC25,Interconnection of InformationTechnology Equipment

Chair elections for each of the even-numbersubcommittees were held in January 2002 inline with the requirements of the revised TIAEngineering Manual, and chair elections forodd-number subcommittees were planned forJanuary 2003.
