Using A Telephone To Program The System

Perform Class of Service configuration programming from station port 10 or station port 12. The
system will not accept programming commands from any other station port in the system. For
best programming results, use an LCD speakerphone and a DSS/BLF console at station port 11
or 13 to see which features are assigned to individual stations. While you can install any
non-LCD digital telephone and use it for programming, visual feedback of the programming
operations will not be available. You must always keep the handset of the LCD speakerphone
on-hook while you use this telephone to program the system.
NOTE: Be sure the system is not in the night transfer (of ringing) mode of operation
3.2.2

Supporting DigiTech Telephones (Revision I And Later)

There are several items that you need to consider when connecting revision I and later DigiTech
telephones to the DSU II digital telephone system:
• Always program station ports to provide ringing line preference to revision I and later
DigiTech telephones (and to all Impression and Impact telephones) that are connected there.
This action is necessary to activate the orange LED feature on these telephones. The orange
status light indicates a ringing line to distinguish it from lines that are in use or on hold.
