Avaya 6211 Mode D'Emploi

When a digital voice terminal must be installed at a loop-length distance in excess of 5000 ft, a DCP
repeater must be installed in its wiring path. The DCP repeater is a circuit board that has been designed

for mounting on a 100-pair, 110A wiring block. It boosts and cleans up the signals to and from the
terminal, and extends a terminal’s loop length 5000 ft. A maximum of six repeaters can be linked
together. Repeaters are intended to serve small numbers of terminals.

Repeaters are not hermetically sealed, which prevents their use in manholes and on utility poles.  Install
the repeaters in a closet that has 110 VAC power. If a repeater is exposed to electrical hazards, install
primary protection before it.

Ensure that the circuit breaker to the 110 VAC power for the repeaters is labeled with a notice
cautioning personnel not to disrupt power to the repeaters. However, the repeaters do contain a reserve
battery that permits them to operate for about two hours after AC power has been shut off or disrupted.
When multiple repeaters are linked together, each one requires a 110 VAC power source and each
source must be labeled to prevent accidental disruption of power to any repeater. If the AC power to
any repeater in a chain is disrupted, the voice terrninal stops operating (once that repeater’s reserve
battery expends itself).

Exposed DCP repeaters require a data link protector (DLP). See chapter 3, Secondary Protectors,  for

DLP information.

The price element code (PEC) for the DCP repeater is 9601-017.
