Multi-Frequency Module (MFM)
The MFM installs in any position on any processor card and in the daughterboard position of
the TEPRI card. The main purpose of the MFM is to provide DSPs for DTMF and tone
detection.
The receivers are also used for AC15 trunks and DISA.
y
12 DSPs for DTMF and tone detection.
Expanded Switch Module (ESM)
The ESM is used to expand the time switch matrix from 512 channels in a single cabinet to
the 1024 channels required for a multiple cabinet system. It is also required in single cabinet
systems running ‘L’ version software.
The ESM daughterboard installs in position
LOC1
of the MCP2 card and comprises:
y
1024 x 1024 time switch
R2/CID Module (RCM2)
The RCM2 installs in any position of any processor card. The main purpose of the RCM2
daughterboard is to provide Caller ID decoders for use with SLI ports to send FSK signalling
to analogue phones. A secondary use of the RCM2 is to provide R2MFC senders and
receivers to the system, although these are not widely used. The system can support up to
three of these cards for a total of 42 CID receivers.
The RCM2 comprises:
y
14 CID receivers (for use with Caller ID on SLI ports)
Miscellaneous Function Module (MISC)
The MISC daughterboard installs:
y
in position
LOC3
on the MCP2 card in a single cabinet system, or
y
in position
LOC2
on the SCP2, or position
LOC2
on the LCP2, in a multiple cabinet
system.
It provides external music on hold/audio inputs (radios, digital announcers, etc.), external
paging audio output, loud bell, common bell and assignable dry contact closures. The system
can support up to three of these daughterboards, one on the MCP2 or SCP2 and one on
each LCP2. The MISC comprises:
y
Two external music/audio inputs
y
One external paging audio output
y
One loud bell relay contact closure
