Connector pin assignments
The analog message waiting line card brings the 16 phone lines to the IPE
backplane through a 160-pin connector shroud. The backplane is cabled
to the I/O panel on the rear of the module, which is then connected to the
MDF by 25-pair cables.
Telephone lines from station equipment cross connect to the analog
message waiting line card at the MDF using a wiring plan similar to
that used for trunk cards. A typical connection example is shown in
Figure 121 "Analog message waiting line card - typical cross connection
example" (page 475)
and Table 118 "CLASS modem card - environmental
specifications" (page 317) shows the I/O pin designations at the backplane
connector. This connector is arranged as an 80-row by 2-column array of
pins. Normally, these pin positions are cabled to 50-pin connectors at the
I/O panel in the rear of each module for connection with 25-pair cables to
the cross-connect terminal.
The information in Table 199 "Analog message waiting line card -
backplane pinouts" (page 474) is provided as a reference and diagnostic
aid at the backplane, since the cabling arrangement may vary at the I/O
panel. See Communication Server 1000M and Meridian 1 Large System
Installation and Configuration (NN43021-310) for cable pinout information
at the I/O panel.
