FCC Class A and Class B Statements

This section lists the Class A and Class B statements for the Kathrein CCU (Central Con-trol Unit). The information for users of Class A products is included in this section in the

event that EMC performance is degraded due to the addition of a Class A product.

This product has been tested and verified to meet Class B requirements as defined inCFR 47 part 15 for the United States an in EN55022 as well as CISPR 22 for Europe andother international marketplaces. This product has been tested in its customer orderableand shippable configuration, including certain port adapters and accessories representa-tive of typical customer applications and meets Class B requirements.If you add any additional accessories or other features to this product that are tested andmeet requirements that are less than Class B (i.e., Class A), then the product may as-sume the behavior and characteristics of a Class A device. Class A products producemore RF emissions than a Class B product and may cause allowable interference toother products.

FCC Compliance for Class A EquipmentModifying the equipment without Kathreins authorization may result in the equipment nolonger complying with FCC requirements for Class A or Class B digital devices. In thatevent, your right to use the equipment may be limited by FCC regulations, and you maybe required to correct any interference to radio or television communications at yourown expense.

For Class A equipment:

This equipment has been tested and found to comply with the limits for a Class A digitaldevice, pursuant to Part 15 of the FCC rules. These limits are designed to provide rea-sonable protection against harmful interference when the equipment is operated in acommercial environment. This equipment generates, uses, and can radiate radio fre-quency energy and, if not installed and used in accordance with the instructions manual,may cause harmful interference to radio communications. Operation of this equipment ina residential area is likely to cause harmful interference in which case the user will be re-quired to correct the interference at this own expense.

FCC Compliance for Class B Equipment

The Central Control Unit (CCU) generates and may radiate radio-frequency energy. If it isnot installed in accordance with Kathreins installation instructions, it may cause inter-ference with radio and television reception. I has been tested and found to comply withthe limits for a Class B digital device in accordance with the specifications in part 15 ofthe FCC rules. These specifications are designed to provide reasonable protectionagainst such interference in a residential installation. However, there is no guarantee thatinterference will not occur in a particular installation.

You can determine whether your equipment is causing interference by turning it off. Ifthe interference stops, the equipment you turned off was probably causing the interfer-ence. If the equipment causes interference to radio or television reception, try to correctthe interference by using one or more of the following measures:

- Turn the television or radio antenna until the interferences stops.

- Move the equipment to one side or the other of the television or radio.

- Move the equipment farther away from the television or radio.

- Plug the equipment into an outlet that is on a different circuit from the television orradio. (That is, make certain the equipment and the television or radio are on circuitscontrolled by different circuit breakers or fuses.)

Modifications to this product not authorized by KATHREIN-Werke KG could void the FCCapproval and negate your authority to operate the product.

1.4 RET System Control

The major component for controlling the RCU is the Central ControlUnit (CCU), which is located at the BTS.

In order to cover all required applications, the CCU can be accessedvia Ethernet or RS 232 interface. For example, access can thereby beachieved from WAN/LAN networks (TCP/IP) or directly on site bymeans of a personal computer (PC).

The following transport and application protocols are served by theCCU: TCP/IP, PPP, UDP, DHCP, HTTP/HTML, ICMP/Ping, FTP andSNMP.

The overall connection of the RCUs to one CCU can be effected viaseparate control cables (1).

It is also possible to connect RCUs and CCU via feeder cable by us-ing Smart Bias Tees (SBT). One SBT is mounted near the BTS for bi-asing the RCU and to convert the control Signal to a modulated carriersignal. A second SBT is mounted near the antenna to extract the DC

voltage and control signal from the feeder line (2).

An elegant way of controlling the RET system is to combine aKathrein TMA and a RCU. Both the control signal and DC power sup-ply are fed onto the RF cable via Smart Bias Tee.The TMA includes a Smart Bias Tee function and takes these signalsand voltage from the feeder cable and forwards them to the connectedRCUs (3).

It is very important to keep written records that match up the serialnumber for each Remote Control Unit (RCU) with the antenna loca-tion (sector, position, frequency band) that it will be attached to.Remember that dual or triple band antennas can have more thanone RCU attached. The written records will be used for program-ming the Central Control Unit (CCU) after the equipment is in-stalled.

RCUs should be attached to the antenna only after the antenna isrigged on the tower and the feedlines have been installed. This al-lows for proper torquing of the feedline connectors and preventsdamage to the RCU while the antenna is being hoisted up thetower.

The bottom end-cap of each antenna has a label showing locations

of the connectors (+/- 45 ports) and for dual and triple band an-tennas, the positions of the tilt adjuster mechanism for each band.

2.2 Control Cable Installation

Install the control cable according to the installation manual of the respective operator.

RET system Control Cables must be properly dressed on towerto provide strain relief for the connectors and prevent damagefrom ice loading or repeated flexing caused by windy conditions.

There is one Male connector and one Female connector on eachRET Control Cable. BE SURE TO INSTALL THE CABLES SOTHAT THE FEMALE CONNECTOR IS AT THE TOP OF THETOWER.

2.4 Installation/Operation of the RET-System

Before installing the RET System, carry out the following:

It is recommended to document the results separately as you willneed this information to configure the RET System.

- Determine the connected antenna types

- Match the serial numbers of the RCUs which will be con-nected to the respective antennas

- Determine the RCU arrangement in the different sectors

Connect the RCUs to the respective antenna (follow instructionsunder section Attachment of RCU).

Install, if required, other RET components such as Splitter, Con-trol Cable and/or LPD.

Put the CCU into the designated rack. Both, horizontal or verticalinstallation is possible.

The installation of the equipment is confined to Restricted AccessLocations (RAL).The CCU is only suitable for indoor use!

Increased Ambient Operating Temperature:

If the equipment is installed in a closed or multi-unit rack assem-bly, the operating temperature of the rack environment may behigher than the ambient room temperature. Therefore, install theequipment in an environment where the maximum ambient tem-perature limit (TMA) specified in the individual data sheets is pro-vided.Heat accumulation may otherwise occur and result in destructionof the device.

Reduced Air Flow:If the equipment is to be installed on a rack, make sure that the airflow required for safe operation of the equipment is not impeded.Never install the CCU in a cabinet, shelf or rack with inadequate

ventilation.Heat accumulation may otherwise occur and result in destructionof the device.

Mechanical Loading:Mounting the equipment on a rack should be carried out in such away that no hazardous situation due to uneven mechanical loadingoccurs.Extraordinary operating conditions, such as heavy icing or excep-tional dynamic stress (e.g. strain caused by oscillating supportstructures), may result in the supporting structure, antenna or RETcomponent breaking, or even cause it to fall to the ground.

Circuit Overloading:Mind the connection of the equipment to the supply circuit, andthe effect that overloading of the circuits might have on the over-current protection and the supply wiring.

NOTICE

Appropriate consideration of equipment nameplate and data sheetratings should be used when addressing this concern.

Proper Earthing:Proper earthing of rack-mounted equipment should be maintained.Particular attention should be paid to supply connections otherthan direct connections to the branch circuit (e.g. use of power

strips).

The RET applications must be grounded according to the relevantlocal regulations!

Connect the control cable(s) to the RCU interface at the CCUfront panel. (1)

For the DC connection, please only use the enclosed connector.

Check the polarity of the DC cable before you make the connec-tion.

Make the connection between power supply and the DC interfaceat the CCU. The CCU is automatically operating after the CCUhas been connected to the power supply.

If the CCU has an AC power plug, the CCU can also be poweredby AC power cable (3).The AC power supply has priority and switches off the DC powersupply automatically. The DC power supply can operate as abackup power supply.

The power supply system of the CCU must be fuse protected.

In case of AC powering, the nominal value of the breaking cur-rent must be less or equal to 20 Amps.

In case of DC powering, the nominal value of the breaking cur-rent must be less or equal to 10 Amps.

3.2 In General

The CCU delivers 13 V and 29 V power supply to the connected AISG devices.

You can connect up to 27 RCUs to the CCU. Each CCU output supports up to nine RCUs if they arepowered by 13V. If the RCUs are powered by 29V you can distribute them to the CCU outputs asrequired by the system configuration. Each RCU can be identified and controlled individually via itsserial number.

Due to power losses along the cables, there is an interrelationship between the number of the con-nected RCUs, TMAs and the maximum cable length.

Each of the three CCU outputs is suitable for the connection of one TMA and up to nine RCUs

3.3 Use of Control Cable

The maximum control cable length (Lmax) depends on the type of RET configuration (see the examples inthis chapter).

In star configuration with one control cable for each sector, the max. length of the control cable depends on

the number of RCUs per sector (N_RCU/sector). In daisy-chain configuration, the max. length depends onthe total number of RCUs (n_RCU).

The length values (29V) are listed in the tables below.
