Connector pin assignments 143
The OPS analog line card brings the eight analog telephone lines to the IPE
backplane through a 160-pin connector shroud. The backplane is cabled
to the input/output (I/O) panel on the rear of the module, which is then
connected to the Main Distribution Frame (MDF) by 25-pair cables.

OPS analog line card - typical cross connection example
Telephone lines from station equipment cross connect to the OPS analog
line card at the MDF using a wiring plan similar to that used for trunk
cards. A typical connection example is shown in
Figure 23 "OPS analog
line card - typical cross connection example" (page 143) , and a list of the
connections to the analog line card is shown in Table 70 "OPS analog line
card - backplane pinouts" (page 142) . See Communication Server 1000M
