2-5Multi-Frequency Module (MFM)The MFM installs in any position on any processor card and in the daughterboard position ofthe TEPRI card. The main purpose of the MFM is to provide DSPs for DTMF and tonedetection.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 tothe 1024 channels required for a multiple cabinet system. It is also required in single cabinetsystems running ‘L’ version software.The ESM daughterboard installs in position LOC1 of the MCP2 card and comprises:y 1024 x 1024 time switchR2/CID Module (RCM2)The RCM2 installs in any position of any processor card. The main purpose of the RCM2daughterboard is to provide Caller ID decoders for use with SLI ports to send FSK signallingto analogue phones. A secondary use of the RCM2 is to provide R2MFC senders andreceivers to the system, although these are not widely used. The system can support up tothree 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, ory in position LOC2 on the SCP2, or position LOC2 on the LCP2, in a multiple cabinetsystem.It provides external music on hold/audio inputs (radios, digital announcers, etc.), externalpaging audio output, loud bell, common bell and assignable dry contact closures. The systemcan support up to three of these daughterboards, one on the MCP2 or SCP2 and one oneach LCP2. The MISC comprises:y Two external music/audio inputsy One external paging audio outputy One loud bell relay contact closure
