PDMs are connected to TN754 digital line circuit packs and are
mounted individually or in a 71A data mounting. Each 71A data
mounting can contain eight PDMs. This guide contains only the
information required to connect the PDMs to the switch. PDM installation
and testing information is contained in AT&T System 75 User’s
Guide—Processor Data Module, 999-700-028.
The data mounting is connected by an A25D/B25A cable through the
cross-connect field to a TN754 digital line circuit pack. The PDMs can
also be mounted and connected individually through the cross-connect
field.
Installation
Connection to Data Mounting (Figure 5-21)
1. From the Data Module Form, determine port assignment of PDMs:
EXAMPLE:
Carrier Slot Circuit
Port Number
B
0 2
01
2. Connect an A25D (for 110-type hardware) or B25A for 66-type
hardware) cable to the DCP-LINE connector on the rear of the data
mounting.
3. Route the cable from the data mounting to the station side of the
cross-connect field.
4. For 110-type hardware, install a yellow (auxiliary) label on the
110-type terminal block. For 66-type hardware, write the lead
designations on the 66-type connecting block with a felt-tipped pen.
5. Connect patch cords/jumper wires at cross-connect field (Figure
5-21).
6. Administer per AT&T System 75 and System 75 XE—lmplementation
(555-200-651) and AT&T System 75 and System 75 XE—Administration
(555-200-500).
