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
connections for multimedia call handling.
The C-LAN ethernet port is indirectly associated with the C-LAN IP address via the
slot location (which is part of the port location) on the IP Interfaces screen and the
node name, which is on both the IP Interfaces and Node Names screens.

Troubleshooting IP Solutions 2 H.323 Trunks Administration for Network Connectivity CID: 77730 555-233-504 — Issue 1 — April 2000 50 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 have different attributes, it is usually better to assign each H.323 trunk group to a separate signaling group. An H.323 signaling group directs all incoming calls to a single trunk group, regardless of how many trunk groups are assigned to that signaling group. This is specified in the field “Trunk Group for Channel Selection” on the H.323 signaling group screen. In the example shown in Figure 2, two trunk groups are assigned to the same signaling group on each of two switches, A and B. Trunk groups A1 and B1 are set up to route calls over a private network. Trunk groups A2 and B2 are set up to route calls over the public network. The signaling group on switch B terminates all incoming calls on trunk group B1 as specified by the “Trunk Group for Channel Selection” field. Calls from switch A to switch B using trunk group A1 and the private NW are terminated on trunk group B1, as desired. However, calls from switch A to switch B using trunk group A2 and the public NW are also terminated on trunk group B1, not trunk group B2, which would be the desired outcome.
