Task 3 — Assign Link via ethernet Data Module to the LAN  
This task administers an ethernet data module for the connection between the C-LAN 
board’s ethernet port (port 17) and the LAN. The data module associates a link 
number and extension number with the C-LAN ethernet port location. This 
association is used by the DEFINITY processor to set up and maintain signaling...

Task 4 — Create a signaling group  
This task creates a signaling group that will be associated with H.323 trunks that 
connect this switch to a far-end switch. One or more unique signaling groups must be 
established for each far-end node that this switch is connected to via H.323 trunks.
Note:The following steps address only those fields that are specifically related 
to...

Far-end Node Name: This is the node name for the far-end C-LAN IP 
Interface used for trunks assigned to this signaling 
group. The node name must be administered on the 
Node Names form on this switch.

Task 5 — Create a trunk group  
This task creates a new trunk group for H.323 trunks. Each H.323 trunk must be a 
member of an ISDN trunk group and must be associated with an H.323 signaling 
group.
Note:The following steps address only those fields that are specifically related 
to H.323 trunks. The other fields are administered as for previous releases 
and are described...

Note:Each signaling group can support up to 31 trunks. If you need more than 
31 trunks between the same two switches, add a second signaling group 
with different listen ports, and add a second trunk group. See Signaling 
group assignments  (page 50) for more information about the relationship 
between...

Troubleshooting IP Solutions 
This section provides solutions to some commonly encountered problems with H.323 trunks and IP Softphones.
H.323 Trunk Problem Solving
Signaling group 
assignmentsMultiple H.323 trunk groups can be assigned to a single signaling group, as with 
standard trunk groups that use circuit-switched paths. However, when multiple H.323 
trunk groups...
