Connector pin assignments
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.
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 22 "OPS analog
line card - typical cross connection example" (page 132), and a list of the
connections to the analog line card is shown in Table 56 "OPS analog
line card - backplane pinouts" (page 131). See Communication Server
1000M and Meridian 1 Large System Installation and Configuration
(NN43021-310) for more detailed I/O panel connector information and wire
assignments for each tip/ring pair.
