DIRECT-IN TERMINATION (DIT)-PRI
1. General Description
This feature automatically routes incoming network exchange calls from an ISDN network and Public/Private
Telecommunication network directly to a preselected station without Attendant assistance. The call can then be

the same manner as any normal trunk call.

at a predetermined station, bypassing the ATTENDANT CONSOLE [A-3].
