Step 4: 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
2
(4 mm ) 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.

Installing the CBC

Before you begin, be sure the telephone lines are cross-connected to the appropriate media
module(s).
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 in (30.5 cm) away from
Note:
exposed telephone cables whenever possible.
Step 5: Installing the Avaya Partner Contact Closure
Adjunct
The Contact Closure feature is a controllable relay providing dry contacts for various
applications. To implement the contact closure feature, you connect an Avaya Partner Contact
Closure Adjunct box to the CCA port on the G350 chassis. The adjunct box provides two
contact closures that can be operated in either a "normally closed" or "normally open" state. The
contact closures can control auxiliary devices such as devices that automatically lock or unlock
doors or voice recording units. The CCA port can be configured so that the connected devices
can be controlled by an end device, such as a telephone. For example, a user can unlock a
door by keying a sequence into a telephone keypad.
