Nortel Integrated Conference Bridge Service Implementation Guide
For the secondary 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 secondary 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 
secondary card.
TUI DN – This is the DN that users dial to set up single-card 
conferences on the secondary card. Do not configure this DN, if the 
the TUI is not going to be used.
Transfer DN – This is the DN that transfers dual-card conference 
participants from the primary card to the secondary card when the 
primary card reaches capacity. The primary card fills up first in a 
dual-card conference. Configure this DN for dual-card setup.
Link DN – This is the DN the creates a speech path between the 
primary card and the secondary card for dual-card conferences. 
Configure this DN for dual-card setup.
Therefore, for the secondary card, configure up to 22 DNs in LD 23 that 
Night Call Forward (NCFW) to the ACD DN of the secondary card.
The main DN must also be configured for the dual-card conference. The 
main DN is the DN that conferees dial to enter the dual-card 
conference. When the conferees dial the main DN, the main DN 
forwards them to the ACD queue of the primary card. When the primary 
card becomes full, the transfer DN transfers further conferees to the 
secondary card. Use Table 8 to configure the main DN for dual-card 
conferences
.
