SoR Automated Process – Further Information• New automated front end process through the Openreach Web Portal – see

http://www.openreach.co.uk/orpg/news/generalbriefings/downloads/Briefing%20GEN0019_08.pdf

• and the reception process is described here http://www.openreach.co.uk/orpg/products/newproducts/downloads/08_02_28_Automated_SoR_Issue _1.pdf

• Better control and accountability to the CP – it does not change the overall process.

• Greater opportunity and ease for all our CPs to submit SoRs.

• Allows CPs to track the status of their SoRs.

• The process allows the CPs to share the brief description of the SoR with the rest of the Industry if they wish to do so.– Within the template there is a tick box that allows you to share the outline “Brief

description” box of the SoR with other Customers (CPs) if so desired.– Recommended as this allows Openreach to gauge demand and benefit to Industry as

a whole

Openreach policing rules above apply here CP policing rules apply here

– Incorrect 802.1p markings will be treated by Openreach as 2 (and may result in random discard of traffic under congestion scenarios)

– CP Must shape traffic (per VLAN) otherwise there may be random traffic discard– There may be packet re-ordering if an application marks traffic with different .1p markings i.e.

some traffic as ‘3’ and some traffic as ‘2’ (The detailed design is still being worked through, if this is an issue it will be confirmed once the detailed design is complete)

Mark with 802.1p ‘3’

Mark with 802.1p ‘2’

Technical Trial Testing

Andrew Sheppard / Amir Rashid


Kesgrave Trial Preparation• 62 Customers connected and operational since Christmas

– no equipment faults

• Openreach is:– Conducting war games on network provision and repair processes– Conducting lab tests of ‘Peak Rate’ products– Developing Service and Infrastructure solution designs for ‘Peak Rate’

products– Developing plans to introduce the ‘Peak Rate’ products to the trial

• CP Interaction– Inter-working Model built and commissioned – Transportable model of OLT,

PON’s and ONT’s. Available for CPs to book for Lab based Service Testing. – Access for CP to an OSS test environment (proposed for 21st April – 2nd

May)– Workshops held / ongoing with CPs and SPs who have agreed to take part

in the trial to plan trial customer handover, and agreement on trial processes. Current plan is for CP trials to commence early May 08


Kesgrave Trial Preparation (cont’d)• Open disclosure to engaged CPs (BT Wholesale initially) of

Openreach’s pre-trial technical ‘war gaming’ testing and results.

• Openreach has shared with BT Wholesale the End Customer Trialist contact information for those end customers who have consented.

• Agreement between Openreach and CPs to work together to ensure all aspects of FTTP and e2e service are proven as early as possible.

• Fibre IRS – Trial plan still in review

Heat Dissipation of home wiring

cabinetAndrew Sheppard


Q: How is heat dissipated in the home wiring cabinetThermal management tests to estimate the max. temperature that equipment is likely to experience within the cabinet, and the cabinet temperature itself

Key issue – heat dissipation and layout of non-Openreach equipment is unknownCabinet was fitted with a Huawei ONT plus 50 W source to simulate the estimated heat dissipation of CP and Structured Wiring equipment.

Cabinet was tested in two scenarios –• Vented - Free standing, doors closed and heat Vents unobstructed• Un-vented - Doors closed, draped with an insulating material and heat vents blocked.

ResultsVented Max. temperatures – cabinet top 32ºC, ONT compartment 23ºC and ONT case 23ºC

Un-vented Max. temperatures – cabinet top 48ºC, ONT compartment 29ºC and ONT case 26ºC

ConclusionWith a 50W heat dissipation from non-Openreach equipment located in the cabinet, the ONT is operating well within its maximum operating temperature of 50ºC.

Cabinet temperature within health and safety specification limit – EN60950 Part 1

Voice Obligations

10th April 2008

Phil MarkloveVoice Strategy


Topics

• Voice Obligations & Responsibilities

• FTTP enables CPs to meet their responsibilities

• Some specific Obligation Impacts


Voice Obligations & ResponsibilitiesObligation Responsibility

Universal Service Obligations (USO) BT and KCom only

The 4 criteria that designates a service as being a Publicly Available Telephone Service (PATS) are;

Publicly availableProvides National CallsUses telephone numbersOffers 999 access

Applies to all Voice/VOIP Providers (CPs)

'General Conditions of Entitlement‘ apply to providers of PATS services and bring into force a certain set of the General Conditions.

Apply to all CPs who meet PATS criteria


FTTP enables CPs to meet their responsibilities

• Openreach product from R to S• VEP – Voice Enablement Product (135kbps)• DP – Data Product (various bandwidths offered)

FTTP enables CPs to meet their responsibilities• Openreach enables a Voice solution over GEA through the Voice

Enablement Product (VEP). CPs need to integrate VEP into their end- to-end voice solution through the provision of suitable call server, network and equipment in the home.

• VEP sizing based on 10ms G711 encoding standards and sized to meet PSTN quality latency, jitter, QOS requirements

• Lab testing has confirmed the VEP meets the latency, jitter and QOS requirements for USO voice.

• Lab testing has confirmed the DP can support upstream and downstream bandwidths and prioritisation (802.1p). Lab testing has proven derived Voice over the DP to 2 service providers.

• FTTP availability/reliability better than copper by approximately a factor of 10.


General Condition 3

“…all reasonably practicable steps to maintain, to the greatest extent possible;

(a) the proper and effective functioning of the public telephone network at fixed locations at all times,

(b) the availability of the network and service in the event of catastrophic failures or cases of force majeure,

• No metrics quoted but benchmark for comparison will be PSTN

• Voice Quality dependent on:– Bandwidth/Codec, i.e. 64kbps G.711– Jitter, Packet Loss, Delay end to end

.

Some specific Obligation impacts


General Condition 3 cont’d

Design areas for CPs– Prioritisation of voice traffic over data traffic End to End– Voice and data traffic mix and impact on network policies – Resilience to registration storms– Overload Control

• Service assurance, availability– Service monitoring and SLA reporting– Service availability, resiliency and failover measures,

restoration times– Proactive and reactive fault detection and resolution

(c) and uninterrupted access to Emergency Organisations

• Battery Backup of the ONT is an Openreach responsibility

• Battery Backup of the ATA/Home Phone is currently assumed to be a CP responsibility – 4 Hours Backup (but Openreach is examining options in this area).



Some specific Obligation impactsGeneral Condition 4

(4.2) where technically feasible make caller location information available to the emergency services.”

• For FTTP the primary line number will be fixed to the ATA in the customer premises

• Marginal risk of customer detaching equipment from cabinet.

• T&C’s, physical protection, VOIP flag may need to be set by CP Call server – end user address is confirmed by operator


Some specific Obligation impactsGeneral Condition 5

“…requires providers to co-operate with government and the emergency services to make arrangements for the provision and rapid restoration of such services, as are practicable and may reasonably be required, in the event of disasters.”

• BT Design deliver Infrastructure to maintain service on 20C/21C in the event of a disaster scenario. Can range from providing mobile phones, pay phones to providing containers with switch processors etc and connecting to the access and northbound networks. BT Operate manage the network once provided.

• Openreach is in discussion with BT Design regarding the practicalities of a solution for restoration of FTTP components.

• CPs may wish to provide their own disaster recovery capability or engage a 3rd party.


General Condition 18

“…requires all providers to provide number portability as soon as practicable and on reasonable terms but only to subscribers of publicly available telephone services who request it.”

• General condition solely concerned with ‘number export’ to another CP

• Ofcom proposing new telephone number range for Ebbsfleet region and out for consultation (01987)

• Aiming to have a number portability solution available for launch



Some specific Obligation impactsUniversal Service Obligation Article 19

Carrier selection and carrier pre-selection

National regulatory authorities shall require undertakings notified as having significant market power for the provision of connection to and use of the public telephone network at a fixed location in accordance with Article 16(3) to enable their subscribers to access the services of any interconnected provider of publicly available telephone services:

(a) on a call-by-call basis by dialling a carrier selection code; and

CPs affected by the USO will be expected to provide Indirect Access.

(b) by means of pre-selection, with a facility to override any pre- selected choice on a call-by-call basis by dialling a carrier selection code.

For Ebbsfleet pre-selection is provided inherently by the GEA product.

Thank you
