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.
