Overload level

Signal levels exceeding +7 dBm applied to the tip and ring cause distortion in speech
transmission.

Connector pin assignments

The analog message waiting line card brings the 16 phone lines to the IPE backplane through
a 160-pin connector shroud. The backplane is cabled to the I/O panel on the rear of the module,
which is then connected to the MDF by 25-pair cables.
Telephone lines from station equipment cross connect to the analog message waiting line card
at the MDF using a wiring plan similar to that used for trunk cards. A typical connection example
is shown in
example on page 375 and
pinouts on page 374shows the I/O pin designations at the backplane connector. This
connector 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 cross-connect terminal.
The information in
page 374is provided as a reference and diagnostic aid at the backplane, because the cabling
arrangement may vary at the I/O panel. See Communication Server 1000M and Meridian 1
Large System Installation and Configuration (NN43021-310) for cable pinout information at the
I/O panel.
