Caller ID Trunk Media Bay Module
There are two types of Caller ID trunk media bay modules (CTM):
1. CTM4:
The CTM4 connects a maximum of four analog calling line ID (CLID)
interfaces to the BCM system through four RJ-11 jacks on the front
faceplate of the MBM. These jacks are labelled Line 1,Auxiliary, Line
2, Line 3, and Line 4. The auxiliary jack connects to Line 1.
2. CTM8:
The CTM8 provides eight analog CLID interfaces to the BCM system
through eight RJ-11 jacks on the front faceplate of the BCM. Each jack
also supports disconnect supervision. There are two auxiliary jacks on
this MBM which connect to Line 1 and Line 5.
The auxiliary ports will interface to a V.92 or V.90 modem, fax machine
unit, or analog telephone. When the auxiliary device is active, the BCM
system disables the associated line. If the line is active, the auxiliary
port line is disabled.
When an analog telephone is connected to the auxiliary port, it can be
used as an emergency telephone because this line remains active
during a power outage.
