Connecting Telephones and Adjunct Systems
Complete the Telephone Installation Process
Installation and Upgrades for G700 and S8300 331
December 2003
Complete the Telephone Installation Process
Consult the planning documentation to obtain the necessary information to complete the installation. Part
of the final process will be to:
• Complete the electrical installation
• Enable adjunct systems
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
2
) wire tie wrapped
to 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 telephone lines are cross-connected to the appropriate media module(s).
Install the CBC
1 Connect one end of the conductor to a telephone cable building entrance protector ground that is
connected to an approved ground.
2 Route the rest of the conductor next to the exposed telephone cables being protected until they
reach the cross-connect nearest to the telephone system.
3 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:
• Avaya MM712 DCP: either 146E IROB (In-Range Out-of-Building) or 4C3S-75 solid state
protectors for surge and sneak current.
• Avaya MM710 T1/E1: over-voltage and sneak protection for the Avaya MM710 T1/E1 Media
Module is provided on the Media Module itself.
