In DSX-80/160, PRI provides for connection to advanced digital lines and simplifies
installation.

Similar to T1, PRI gives the system the advantages of advanced digital calling as well as conserving PCB slots. For example, you can set up a system with 12 loop start lines and 11 DID lines and use only a single PCB slot. Additionally, the T1/PRI PCB has its own on-board processor and DSP so it minimally impacts other system resources.
Incoming Calling Party Number is available on Loop Start DTMF and DID Immediate Start DTMF PRI lines when the Caller ID Type is set to T1/PRI.
An extension’s Class of Service can optionally enable or disable Outgoing Calling Party Number Privacy. When an extension has Privacy enabled, the call recipient should see “Private Number” in their Caller ID display for calls over a PRI line from the extension. If disabled, the call recipient sees the Outgoing Calling Party Number programmed in the system.
