Station Message Detailed Recording
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 manual
contains only information for connection to the PDMs from the system 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 cable through the cross-connect field to a
Digital Line circuit pack. The PDMs can also be mounted and connected individually
through the cross-connect field.
