Module Description
Overview of This Chapter
The 4-Port Voice 2-Wire Office module (20N32) provides support for the
office (central office or PABX switch) end of a two-wire analog telephone
line. This allows a voice loop from a voice switch to be connected directly to a
Multiservice Media Gateway system over an ATM network to a distant tele-
phone or other analog device. The coding translation supported by this mod-
ule is µ-law to µ-law only.
The module has three types of light-emitting diode (LED) indicators:
ACTIVE, FAIL, and LOS (loss of signal). On the faceplate, each port has a LOS
LED which turns on when the port goes off-hook. It also flashes in synchro-
nization with an incoming ringing signal to the port.
