3.2.6 Optional Daughterboards
There are 5 types of optional daughtercards that can be installed
ONLY
on the
LP40
. Each
optional daughtercard must be installed in specific positions of the LP40
optional daughterboard is described below:
Multi-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.
This board has
been discontinued as of 05/2009. The CRM daughter board is a replacement for this part.
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 LP40.
RCM2:
The RCM2 is installed in LOC1 or LOC2 of the LP40 card. This 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.
Common Resource Module (CRM):
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 daughtercards. The CRM card is mounted on LOC1 or LOC2 in the
LP40. The location is indicated on the LP40 card. Two DSPs 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.
This board has
been discontinued as of 05/2009. The CRM daughter board is a replacement for this part.
Switch Conference Module (SCM):
This board has been discontinued as of 05/2009. The
CRM daughter board is a replacement for this part.
Each SCM provides an additional 12
conference circuits (5 parties each). Each SCM also provides 12 DTMFRs. 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 DTMFRs.
o
Each LP40 card (NOT MP40) provides 6 conference circuits. (5 parties ea.) BY
DEFAULT with NO daughtercards installed.
