Section 400-Programming
Notes
Restriction For CPC-B Version 3.1. This address is also present in CPC-B
Version 3.1; however, it only controls Multiple DID (DNIS cannot be used
with this version).
DID Hardware and Power Requirements. The DID trunk card is required;
each card provides 8 ports. The card requires dial-pulse dialing and an
external, -48V power supply. See Section 300-Installation for cabling
instructions.
DID/DNIS Digit Length Requirement. The DBS only supports 4-digit DID/
DNIS numbers.
Central Office Requirement. When the CO sends a DID/DNIS call to the
DBS, it first receives a wink from the DBS before sending the digits. Once
the wink is received, the CO should wait at least 200 ms before sending the
digits.
Trunk Requirement. Individual trunks must be enabled for DID or DNIS
(see FF1 8# 4# 6# Trunk# 2#).
Simultaneous Ringing. If Multiple DID/DNIS is enabled, all extensions
assigned the same DID/DNIS number will ring for the incoming DID/DNIS
call. If you later disable Multiple DID/DNIS, only the extension at the
lowest-numbered port will ring for the DID/DNIS call.
Call Forwarding Interaction. If Multiple DID/DNIS is enabled, and the
DID/DNIS extensions are programmed to call-forward to different
extensions, the simultaneous ringing will also apply to the call-forward
destination extensions. In other words, all call-forward paths will be
followed simultaneously for the same DID/DNIS call, until someone picks it
up. If you later disable Multiple DID/DNIS, only the call-forwarding path
assigned to the extension at the lowest-numbered port will be followed.
