CPC-96, CPC-288, and CPC-576 Version 1.0
Description
Multiple Ringing allows CO calls into the System to be directed to ring multiple extensions in the
System. This can be very useful when anyone in a group may answer a call. This can also be very
useful at night when only a selected number of people are available to handle calls.

Description
The System supports several types of CO Trunk Interfaces including the following:
•
Direct Inward Dialing (DID)
•
Integrated Services Digital Network (ISDN) - Basic Rate Interface (BRI)
•
ISDN - Primary Rate Interface (PRI)
•
Loop Start and Ground Start
Each trunk type supports various features such as Delayed Ringing, Night Ringing, etc.
CO Trunk Interface - DID
The DID feature allows an extension to have a dedicated direct number. The dedicated number allows
calls to be made directly to the extension, without the caller going through the attendant.
The DID number may have from 1 to 4 digits (typically 4).
Each DID Trunk Interface card (VB-44520) supports up to 8 DID trunks.
Hardware Requirements
