Installing the Coupled Bonding Conductor

The Coupled Bonding Conductor (CBC) provides mutual inductance coupling between the CBC and the
telephone cables that are exposed to lightning. The conductor can be a 10 AWG (4 mm
the exposed cables, a metal cable shield around the exposed cables, or six spare pairs from the exposed
cable. In a high-rise building, connect the CBC to an approved building ground on each floor.
Before you begin, be sure the phone lines have cross-connected to the appropriate media module.
Install the CBC
Begin
Connect one end of the conductor to a telephone cable building entrance protector ground that is
1.
connected to an approved ground.
Route the rest of the conductor next to the exposed telephone cables being protected until they
2.
reach the cross-connect nearest to the telephone system.
Terminate the other end to the single-point ground block provided for the telephone system.
3.
End
Note: Position the non-exposed telephone cables at least 12 inches (30.5 cm) away
from exposed telephone cables whenever possible.

Installing Circuit Protection

Over-voltage and sneak fuse protection measures are necessary for the safe operation of the C-Hawk Media
Gateway system.

Over-Voltage and Sneak-Current Protection

Out-of-building installations of telephones or other standard (tip/ring) devices/terminals that connect
to the Avaya G700 Media Gateway Media Modules require over-voltage and sneak current protection
at both building entry points. Sneak current protectors must have a maximum of 350 mA and a
minimum voltage rating of 600V. The following devices have been evaluated or tested and approved
to protect the Media Modules from over-voltages and sneak current protection:
• Avaya MM712 DCP: either 146E IROB (In-Range Out-of-Building) or 4C3S-75 solid state
protectors for surge and sneak current.
• Avaya MM712 DCP: the 4C3S-75 solid state protector for surge and sneak current.
• Avaya MM710 T1/E1: overvoltage and sneak protection for the Avaya MM710 T1/E1 Media
Module is provided on the Media Module itself.
