Troubleshooting Procedure

Solving Connectivity Problems

In general, link connectivity problems can be diagnosed fairly quickly. For clients'
ASAI requests to complete successfully, the ISDN BRI link to the DEFINITY
system must be up and the application must have TCP connectivity to the
CV/LAN server on the MAPD. Release 5.0 of the CV/LAN client software allows
the use of the
"asai_test" command over the LAN. To test connectivity to the DEFINITY system
through a MAPD with hostname or IP address XYZ over ASAI link "signal01,"
execute the following command:
The command "asai_test" will be located under /usr/adm/cvlan/bin directory to
avoid confusion with the /usr/bin/asai_test command that performs a
similar test to the switch using the CallVisor ASAI API.
If the asai_test command cannot establish TCP connectivity to the CV/LAN server
on the MAPD, the client running the command is probably not administered on the
MAPD. A CV/LAN application must be able to readily identify an error via the
asai_errval() client API call. If a client cannot connect to the CV/LAN server on the
MAPD, the application will retrieve the C_INVALID_CLIENT cause. This shows
that perhaps the client has not been administered on the MAPD and therefore
failed authentication by the CV/LAN server. Contact the MAPD system
administrator to add the client to the list of hosts that are allowed to access the
system.
If the ISDN BRI link to the switch is down, asai_test cannot send heartbeat to the
switch. The CV/LAN application on the MAPD offers a variety of utilities and
status screens to diagnose the problem. The recommended procedure is as
follows:
1. Log into the MAPD.
2. Access the Screen, "Main Menu (CV/LAN)" in Chapter 3,

errors on the link.
4. Select the Screen "CVLAN Port Status/Control" in Chapter 3,
the MAPD
DEFINITY system Port State. If the DEFINITY system Port State is other
than CONNECTED, there is no ISDN connectivity to the switch. Try
Busy/Release of the appropriate BRI port on the switch. Then press
UPDATE

and then the Screen "System Logs", and note pertinent
Configuration.'' Check both the CV/LAN service State and the
button on the CV/LAN Port Status/Control screen.
