Install 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

Terminate the other end to the single-point ground block provided for the telephone system.
NOTE:
Position the non-exposed telephone cables at least 12 inches (30.5 cm) away from exposed
telephone cables whenever possible.

Install Circuit Protection
Over-voltage and sneak fuse protection measures are necessary for the safe operation of the G700 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:
