method; the system does not support combinations on the card or card
pair.
Callers to all meetings access the MICB by dialing one common fixed
number. The MICB 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 system and MICB 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 MICB 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 MICB ports for each simultaneous conference, the
system does not tag ports for a specific conference. The MICB counts
the number of reserved ports and compares these against the total
number of ports provided by the MICB card. The MICB then makes sure
that the reserved ports do not exceed the total number of ports provided
by the MICB 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
MICB 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 MICB card issues an announcement warning the
conferees that the conference terminates in 10 minutes.
When the conference time expires, the MICB card issues the final
warning to the conferees. The MICB sends a release message to the
system for all associated MICB ports. These ports become available for
the next planned conference. If there is no other scheduled conference,
they become floating ports which the system does not reserve for any
conference. Floating ports are available to expand conferences in
progress.
