Modem Pool Line Card (asynchronous outbound only)

Standard 5.00
The QPC311 DLC supports SL-1 sets, ADM and ASIM in the following
operating combinations:
•
two independent telephone and two stand-alone ADMs
•
two co-located telephone/ADM pairs
•
one co-located telephone/ADM pair plus one independent SL-1 set and
one stand-alone ADM
•
two ASIM plus two SL-1 sets
The QPC432 4PDLC supports four ASIM or four ports of MCDS-AC.
The QPC430 AILC supports four AIM or equivalent units. It combines the
basic functions of four ADM and provides the drivers and receivers to meet
standard EIA RS-422 electrical interface specifications.
Each customer-supplied asynchronous outbound pooled modem requires
interface, on the analog side, with one port of an MPLC. This provides the
modem VFDN. One MPLC supports up to four modem pool VFDN. (The
MPLC cannot be used for 500 or 2500 type set terminations.) The 500-set line
card is used for inbound modem pools and for synchronous modem pools.
Note: The MPLC and the VFDN are not used with the AMP feature.
