Coupled Bonding Conductor installations
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.

Installing the CBC
About this task
Before you begin, be sure the telephone lines are cross-connected to the appropriate media
module(s).
Procedure
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.
Result
Note:
Position the non-exposed telephone cables at least 12 in (30.5 cm) away from exposed
telephone cables whenever possible.

Avaya Partner Contact Closure Adjunct installations
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 Branch Gateway 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.
