Nortel Integrated Conference Bridge Service Implementation Guide
• An ICB card configured to the maximum capacity of 32 ports and 10
simultaneous conferences requires 87 ACD DNs and 32 TNs/LENs
as follows:
— one ACD DN assigned to the ICB card
— 32 TNs/LENs assigned to the 32 ports (1 PDN and 1 SDN for
each TN/LEN; these can be internal DNs – non-DID)
— 20 ACD DID DNs (10 DN pairs) for dialing into the potential
conferences
Note: For single-number access, replace this with 1 DN.
— 1 DN for TUI access
Full 62-port dual-card conferencing, using the direct meeting access
method, requires the following:
• Two ICB cards and six ACD groups as follows:
— 64 ACD agents (32 for each card), non-DID
— 64 secondary DNs for these agents, non-DID
— 36 DNs for simple conferences (9 pairs in each card)
Note: For single-number access, replace this with 2 DNs (1
for each card).
— 1 DN for dual-card conference access
— 1 DN for dual-card chairperson access
— 1 DN for the link DN, non-DID
— 1 DN for the transfer DN, non-DID
— 2 DNs for TUI access (1 for each card)
This provides a total of 170 DNs, 40 of which are DID.
• Assign an Ethernet port to each ICB card with an IP address, subnet
mask, and gateway during installation.
Note: On the CS 2100/Meridian SL-100, verify that there are
enough DS30A links back to the extended peripheral module (XPM)
to handle the traffic.
