Nortel Integrated Conference Bridge Service Implementation Guide
Single DN access is mutually exclusive from the direct meeting access 
method in a ICB card or card pair. Configure the card for one access 
method; the system does not support combinations on the card or card 
pair.
Callers to all meetings access the ICB by dialing one common fixed 
number. The ICB prompts the caller for the meeting or chairperson DN 
to enter the required meeting. In this mode of operation, configure the 
single-access DN in the Meridian system and ICB only. Access DN 
pairs are pre-coded in the card.
Expand the conference
Conference expansion allows the system to increase the number of 
conferees if there are remaining ICB ports that are both unassigned 
and unused. Allow or deny conference expansion for each conference 
using the browser user interface (BUI) (see the “Add ports as needed 
field” in the 
).
When reserving the ICB ports for each simultaneous conference, the 
system does not tag ports for a specific conference. The ICB counts the 
number of reserved ports and compares these against the total number 
of ports provided by the ICB card. The ICB then makes sure that the 
reserved ports do not exceed the total number of ports provided by the 
ICB card.
If additional (non-scheduled) callers try to join a conference, but there 
are no floating ports, or the system locks out additional conferees, the 
ICB card issues an overflow tone. The system then disconnects the 
call.
If the system releases un-scheduled (floating) ports from a conference, 
they are immediately available to be used by other conferences that 
have the expansion feature enabled.
End the conference
When scheduling a conference, indicate the number of ports, start time, 
and duration of that conference. The conference ends based on the 
start time and conference duration. Ten minutes before the end of a 
conference, the ICB card issues an announcement warning the 
conferees that the conference terminates in 10 minutes. Two minutes 
before the end of a conference, the ICB card issues a second 
announcement warning the conferees that the conference terminates in 
two minutes.
