Network Call Diversion - Nortel ICS Install Manual

Network Call Diversion

Norstar Network Call Diversion (NCD) is a network function
that allows forwarding and redirection of calls outside the
Norstar network when using an ETSI ISDN line. Functionality
is similar to that of External Call Forward (ECF).
NCD redirects calls using the same line on which they arrive.
Call forward is efficient since there is no need for additional
outside lines.
Forwarding calls externally from an extension requires the
user to enter either a Destination Code or Line Pool Access
Code, and the number to which calls will be forwarded.
Examples of NCD include:
• redirecting all calls from an extension to a mobile phone
• forwarding calls to an external destination (rather than to
voicemail), when an extension is busy or the user is
unavailable.
Feature description
NCD is available only over ETSI ISDN lines. It can be
invoked when calls are presented to Norstar/BST extensions
over ISDN lines. The user must program the selected
extension.
NCD is integrated with the following existing Norstar Call
Forward features:
• Call Forward Unconditional (CFU)—implemented on
Norstar Call Forward All Calls (CFAC) ≤›, and
Selective Line Redirection (SLR) ≤ ° ›, also
referred to as Line Redirection. This is programmable by
the user.
