6.4.9 MCM (MULTI-NET CONSOLE MODULE)

The MCM (Multi-Net Console Module) screen is

shown in Table 6-17. This module interfaces to a

computer controlled VRCM-50 Series dispatch

console. The MCM has a digital data connection that

requires a separate full-duplex 9600 baud RS-232

interface called the IDIB (Intelligent Dispatch Inter-

face Bus). The separate data path is required to allow

computer controlled dispatch consoles to monitor and

display the status of other Groups. This status and

display update can take place while the console is busy

with voice communication on another Group. The

information exchanged between the MCM and the

console controls what the MCM receives and transmits

for voice communication.

The MCM connects the 4-Wire 600-ohm

balanced audio with the PCM (Pulse Code Modula-

tion) data paths and communicates to other modules

via the IDB (Intra-Terminal Data Bus). The MCM also

monitors the CSB (Channel Status Bus) to send update

changes to the console via the IDIB (Intelligent

Dispatch Interface Bus).

The MCM is similar to an IDM except it also has

the capability of summing Multiple Group Audio into

the Select Audio. It can also change the audio level of

each Group in the Select Audio. A Conventional Patch

Module (CPM) can only exist with an MCM. There

may be two CPMs per MCM and they must be

installed in the two address slots above the MCM.

Example: MCM card address 40, CPM1 address

would be 41 and CPM2 address would be 42. The

functions of the CPM are controlled by the MCM.
