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.

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

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...

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...
