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
