Figure 4
Single DN access method (one ICB card)
The DNs on the left in Figure 4 can be Phantom DNs or CDNs, instead
of ACD DNs. The DNs must be DID numbers.
In a dual-card system, each card requires its own single-access DN. In
a dual-card set, conferences that span the two cards do not support the
single DN access method. However, in a dual-card set, simple
conferences that use only one card support the single DN access
method.
Figure 5 on page 32 shows the DN configuration in a Meridian system
for the single DN access method when the system uses two ICB cards.
Single DN access requires one DN, instead of the separate 10 DNs
required with direct meeting access.
The figure shows a configuration that supports the following:
• Simple conference contained in the primary ICB – participants dial
the single-access DN at the top of the figure.
• Simple conferences contained on the secondary ICB – participants
dial the single-access DN at the bottom of the figure.
• Meetings spanning both cards – participants dial the “Dual meeting
main DN” in the middle of the figure and the chairperson dials the
“Dual meeting chairperson DN”. The figure shows that dual-card
meetings do not use the single-access DNs.
