About ODU & Coupler, Continued

About theCoupler

The coupler (with two ODUs mounted on it) is used when you want to ensure

hot standby (asymmetrical coupler suggested) or frequency diversity(symmetrical coupler suggested) operation modes and you have only oneantenna.

INTRACOM TELECOM can provide you with specially designed antennas(called integrated antennas with diameter up to 1,8 m or 6 ft) onto which youcan directly mount the coupler without the need of a waveguide. In case youhave a non-integrated antenna, you should get the appropriate mounting kitin order to mount the coupler onto the mast and connect the coupler to theantenna through a waveguide.

The coupler is provided in two versions depending on the attenuation at itsports:

Symmetrical coupler

Asymmetrical coupler

The symmetrical coupler inserts typically equal ODU Antenna attenuationat both ports (ODU#1, ODU#2). The RF attenuation differs with the operating

frequency.

The asymmetrical coupler inserts differentODU Antenna attenuation at the

two ports (Main ODU, Secondary ODU). The RF attenuation differs with theoperating frequency.

Safety Precautions

WORKING ON THE BUILDINGS ROOF

During stormy weather, do not perform any mechanical assembling orantenna beaming works on the buildings roof.

The metal structure of towers / masts is prone to lightning.

PLUGGING / UNPLUGGING THE IF COAXIAL CABLE

Never plug in or unplug the IF coaxial cable of the outdoor transceiverboxes when the respective indoor equipment is powered on andoperating.

There is risk of equipment failure and/or electrical shock, as the IF cablecarries the outdoor transceivers DC operating voltage (48 V).

PROPER GROUNDING

Never power up the indoor equipment not yet connected to a propergrounding system.

There is risk of equipment failure and/or electrical shock.

Ensure that the indoor grounding system measures a path resistance lessthan 4 .

Ensure that an appropriate grounding terminal exists at the proximity of theoutdoor equipment installation position.

ESD PROTECTION

Always use proper antistatic protection (i.e. grounding bracelet,antistatic bags, etc.) when handling the system cards.

Parts bearing the ESD sign (see left) have ESD sensitive exposedcomponents.

Site Prerequisites, Continued

Network port

distributors

Regarding the network ports (inclusive of STM-1, Ethernet, E1) provided by

the indoor equipment, suitable optical (or electrical) network port distributorsshould be available.

The exact location of the network port distributors, as well as the networkports to reserve, should be known prior to installing the indoor equipment.

Also, all the reserved ports on the network port distributors should bequalified and tested before realizing the network connections with the indoorequipment.

Indoorpremises

conditions

The operating conditions (temperature, humidity) at the indoor premisesshould meet the specifications given by the manufacturer of the indoor

equipment.

Indoorgroundingsystem

All racks within the installation premises should be connected to a low-resistance grounding system. The metal body of the rack, into which thesubracks are to be mounted, should be connected to this grounding system.

The enclosure of each subrack must be electrically connected to the racksmetal body (via a short grounding cable) to provide protection againstharmful discharge conditions.

Outdoorgroundingsystem

A dedicated, low-resistance grounding system (typically < 3 ) is required.

A grounding point (designated GND) should be located close to the mountingposition of the radio boxes.

The box of each radio transceiver will be connected to this grounding point,via the supplied grounding cable. This will provide protection against harmfullightning conditions.

Cable conduits Appropriate cable conduits should exist for the routing of installed cables,inclusive of the coaxial IF cable(s) connecting the indoor equipment with the

outdoor transceiver boxes on the buildings roof.



23/77



19


IF cables The IF cables, connecting the indoor equipment with the outdoor equipment,

should be of coaxial 50-ohm type.The maximum length of the IF cables depends on their quality and theattenuation that they impose to the carried IF signal.

Typical lengths can reach 150 m, using a low-cost coaxial cable of 10,5 dB /100 m maximum attenuation at 350 MHz, or 300 m, using a low-loss coaxialcable of 5 dB / 100 m maximum attenuation at 350 MHz.

Under no circumstance should the total attenuation (imposed bythe IF cable itself) exceed 16 dB at 350 MHz.

Outdoorinstallationrequirements

The outdoor equipment, inclusive of the radio transceiver(s) andantenna(s), should be mounted on a mast or on a tower. The tower or themast, should be grounded and bear a lightning-rod.

The pole, onto which the system will be mounted:

- Should have 2,5 to 4 outer diameter

- Should be perfectly perpendicular to allow correct alignment of theantenna.

Each antenna should point toward the antenna of the remote station,according to the planned co-ordinates. No obstacles should exist between

the antennas beaming lobes.



24/77



20


Power supply

requirements

Power consumption and input DC voltage range are as specified by the

manufacturer of the indoor equipment.

Rackrequirements

Rack requirements are as specified by the manufacturer of the indoorequipment.

Lightning

protectionThe network port distributors (optical distributors excluded) and the powersupply distributors should be equipped with the appropriate gas arresters, toprovide protection against lightning conditions.

Such conditions may induce voltage peaks on the cables, and thus disturbthe operation of the indoor equipment. For this purpose, all electricaldistributors should be connected to the local grounding system to allow theinstalled gas arresters to operate.

Preparation ofthe installationpremises

Access to the installation premises must be facilitated during the installationperiod.

Entrances must be large enough to enable the easy transportation of the newequipment.

The floor must be level, smooth and able to bear the load of the equipment.

The roof must be engineered to bear the weight of the service personnel andthe outdoor equipment.

Safety The indoor equipment premises should be of restricted access.

Only trained, authorized personnel should have access to the installedequipment.

Appropriate labeling should exist at points with high risk of contact withhazardous voltage.

A list with emergency phone numbers (e.g. medical assistance numbers)

should be hung at easy-to-view positions.Also, recommended are for safety purposes, a fire detection system and fireextinguishers (installed at easy-to-access points) inside the installationpremises.
