Nortel Integrated Conference Bridge Service Implementation Guide
The ICB card selects the port for dialing out. The port is available if the
number of ports reserved for the conference is greater than the number
of conferees that have joined the conference. When all reserved ports
are taken, the port can be available, if there are un-reserved ports on
the ICB card and the port expansion feature is enabled for that
conference. If all reserved ports are taken and there are no
unscheduled ports available, the system cannot complete the call.
Note: When the chairperson dials out to another ICB conference,
two ports are seized, the dial-out port of the local ICB and the dial-in
port of the remote ICB. This connection can be terminated only if the
chairperson drops the dial-out port of the local ICB. However,
normally the dial-out call is a telephone, so the system only seizes
one port.
Dial-out Authorization
The Dial-out Authorization feature enables the chairperson to connect
external parties to the conference when the desired destination number
is restricted.
This feature uses the Meridian Authorization feature. As such, the
chairperson must be aware of outdialing restrictions and know the
authorization access code (Flexible Feature Code – FFC or Special
Prefix – SPRE on the CS 1000; Auth Access # on the CS 2100/Meridian
SL-100).
The chairperson must enter the whole string of authorization numbers
as the example in Figure 72 on page 138 shows. There are no
confirmation tones or dial tone in the middle of dialing.
