Complete the telephone installation process
Issue 9.1 June 2006 383
Complete the telephone installation process
Consult the planning documentation to obtain the necessary information to complete the
installation. Part of the final process involves:
● Installing the coupled bonding conductor on page 383
● Installing over-voltage and sneak-current circuit protection on page 384
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
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).
To 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:
Note: Position the non-exposed telephone cables at least 12 inches (30.5 cm) away
from exposed telephone cables whenever possible.
