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 “Scheduling window” on page 89).
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.
