The universal trunk card brings the eight analog trunks 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 trunks connect to the universal trunk card at the MDF using a
wiring plan similar to that used for line cards. A typical connection example
is shown in
Figure 199 "Universal trunk card - typical cross connect
, and a list of the connections to the universal trunk
card is shown in
Table 223 "Universal trunk card - backplane pinouts"
.
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.
