External Call Forwarding; Mcdn Trunk Features; Call By Call Service Selection For Pri - Nortel ICS Install Manual

External call forwarding

The system now allows you to forward calls to an external
number. This feature is activated using
telephone.

MCDN trunk features

Systems with MCDN Private Networking connections can
provide these trunk routing features:
• Trunk Route Optimization (TRO) finds the most direct
route through the network to send a call between nodes.
This function occurs during the initial alerting phase of a
call.
• ISDN Call Connection Limitation: The ICCL feature
piggybacks on the call initiation request and acts as a check
at transit PBX points to prevent misconfigured routes or
calls with errors from blocking channels.
• Trunk Anti-tromboning (TAT) is a call-reroute feature that
works to find better routes during a transfer of an active
call. This feature acts to prevent unnecessary tromboning
of trunks. This action occurs after the speech path has been
established.

Call by Call service selection for PRI

Call by Call service selection allows a user to access services
or private facilities over a PRI line without the use of dedicated
facilities. Various types of services such as FX, Tie, and
OUTWATS are available, depending on the Protocol that is
selected. Private network settings are used for tandem
networking and Advanced Private Networking.
Outgoing calls are routed through a dedicated PRI Pool and the
calls can be routed based on various schedules.
