3.2.6 Optional Daughter Boards
There are 5 types of optional daughter cards that can be installed ONLY on the LP40.
Each optional daughtercard must be installed in specific positions of the LP40
Figure 3.9). Each optional daughterboard is described below:
• Muti-Frequency Module (MFM): The MFM is installed in LOC1 or LOC2 of the
LP40 card. This board provides an additional 12 DSP circuits for DTMF tone
detection.
• Miscellaneous (MIS): The MIS is installed ONLY in LOC3 of the LP40 (towards
front of the board). The MIS provides 2 external Music On Hold ports, an external
paging port, a loud bell port, a common bell port, and also provides 2 dry contact
relay ports that connect or disconnects the signal transmission or power supply
with external equipment. The output ports are located in the front panel of the
MP40.
• RCM2: The RCM2 is installed in LOC1 or LOC2 of the LP40 card.
performs the same function as the RCM, analog Caller ID (CID) decoding on
incoming calls. In addition the RCM2 provides CID or FSK signaling on analog
ports. Any CID compatible device connected to analog station ports can display
CID name and number information as received from the telephone company. This
board regenerates CID exactly as the central office sends it. This RCM2 board can
be used in place of the RCM. Use MMC 300 to set CID to SLT "ON" for each analog
port that will have CID. This board has a slide switch to switch between R2 and CID.
This switch should always be in the CID position. R2 signaling is not used in the
USA. The RCM2 board is used to provide 14 Caller ID DSP circuits for Caller ID
detection on loop start trunks.
• CRM (Common Resource Module): The CRM module is an optional module to
detect and generate DTMF signals and CID signals. The CRM performs the
functions of the RCM2, SCM, and the MFM daughter cards. The CRM card is
mounted on LOC1 or LOC2 in the LP40. The location is indicated on the LP40 card.
Two DSP's are available on the CRM card. Each DSP has 8 channels. Each DSP
can be assigned for DTMFR (DTMF Receiver) or CID using MMC 827. Each CRM
also provides 6 additional conference circuits.
• SCM (Switch Conference Module): Each SCM provides an additional 12
conference circuits (5 party each). Each SCM also provides 12 DTMFR's. The SCM
can be installed in LOC1 or LOC2 on the LP40.
o The same SCM from the OS500 can be used on the 7400.
o Each SCM provides an additional 12 DTMFR's
o Each LP40 card (NOT MP40) provides 6 conference circuits (5 parties ea.)
BY DEFAULT with NO daughter cards installed.
