Table 180 "Digital line card - backplane pinouts" (page 440) shows the
I/O pin designations at the backplane connector, which 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 MDF.
The information in Table 180 "Digital line card - backplane pinouts" (page
440) is provided as a reference and diagnostic aid at the backplane, since
the cabling arrangement can vary at the I/O panel. See Communication
Server 1000M and Meridian 1 Large System Installation and Configuration
(NN43021-310) for cable pinout information for the I/O panel.
