When several conferences occur simultaneously in the same ICB card,
the conferee dials the DN assigned to a specific conference. The ICB
card identifies the dialed DN and routes the conferee to the appropriate
conference represented by that specific DN. The system assigns all
ports on the ICB card to the appropriate conference through the ACD
DN assigned to that ICB card. The chairperson dials the chairperson
DN to a specific conference. This number is different from the DN dialed
by the conferees for the same conference.
The ICB performs DTMF detection on ICB ports identified as
chairperson ports. DTMF detects when conferees enter a conference
password. A conference can start without the chairperson. If all
allocated ports for a conference are taken up with conferees, the
chairperson cannot join the conference, unless a port is specifically
reserved for the chairperson. The chairperson can also join if the
system allows conference expansion and there are free, un-scheduled
(floating) ports available.
The first conferee joining the conference hears an announcement
indicating that no other conferee has joined the conference, followed by
60 seconds of music. The system repeats the announcement with 60
seconds of music, until another conferee joins the conference.
Join the conference using the single DN access method
The single DN access method to all meetings provides users with a
alternative method of accessing the ICB. This feature reduces the
amount of Direct Inward Dialing (DID) numbers that have to be
configured in the switch and provides the following benefits:
• Saves 20 DID numbers from the customer’s DID range.
• Saves 20 ACD or Phantom DNs in the Meridian system thereby
providing a cost savings.
• Simplifies installation as there is no DN pair configuration.
• Saves work if a change in the numbering plan is required in the
Meridian system.
The only trade-off is that callers have an additional step when
accessing a meeting (that is, after dialing the single-access DN, they
must enter the chairperson, or meeting, DN of their specific meeting).
Figure 4 on page 31 shows the DN configuration for single DN access
with one ICB card.
