Nortel Networks 555-4001-135 User Manual

When a dual-card conference is defined, two meetings are defined on 
two cards. First, the meeting is booked on the primary card allocating 
the maximum free ports. Second, the meeting is booked on the 
secondary card allocating the rest of free ports for the dual-card 
conference. The user defines a dual-card conference only on the 
primary card.

When a user dials into a dual-card conference, the call can terminate 
either on the primary or on the secondary card. Calls to the dual-card 
conference main ACD DN are forwarded according to the ACD time 
overflow night table. 

On both cards (primary and secondary), the user cannot use the 
dual-card conference pair DNs for a simple meeting. Therefore, nine 
DNs are available for simple meeting and bridges.

For a dual-card configuration, one card functions as the primary card 
and the other as the secondary card. Define for each card an ACD data 
block with an ACD DN in LD 23, as shown in 

For the primary card, configure the following DNs:

•

DN pairs (up to nine) – These pairs serve as chairperson and 
conferee DNs for single-card conferences (less than 32 ports) on 
the primary card.

Note:  If single-number access is being used, DN pairs are not 
required. Instead, define the single-number access DN in this 
step which callers use to access a simple conference on the 
primary card.

•

TUI DN – This is the DN that users dial to set up single-card 
conferences on the primary card. Do not configure this DN, if the 
TUI is not going to be used.

•

Chairperson DN – This is the DN that chairperson of a dual-card 
conference dials to enter a dual-card conference. This DN is 
required for dual-card setup.

Therefore, for the primary card, configure up to 20 DNs in LD 23 that 
Night Call Forward (NCFW) to the ACD DN of the primary card.
