Download from the Succession switch fails

After you download switch configurations from the Succession switch, if no lines
appear in the Symposium TAPI SP database, or if you receive an error message
indicating that the download failed, perform the following tasks:
1
Verify that the text "LD 20" appears in the download.txt file.
2
Verify that an AST value is defined for each TN. The text conversion tool
requires an AST value to write a TN into the Symposium TAPI SP database.

Testing connectivity

Various methods of testing the E-LAN link on the Succession switch are described
in the Succession product documentation. Nortel Networks can request you to run
a troubleshooting session in the logger application to log the messages that are
exchanged during connectivity tests.

Testing the TCP/IP connection

Use the ping command to test the TCP/IP connection from Symposium TAPI SP
to the SCCS or to the Succession switch. To perform a ping on the connection:
1
Open a DOS window on the TAPI server.
2
Type ping [SCCS/Succession switch TCP/IP address]
3
If the ping is successful, a message is displayed saying the host was contacted.
4
If the ping is not successful, a message is displayed saying the host was not
contacted.
5 Close the ping window by pressing Esc.

Idle message when a remote party disconnects a call

When a remote party disconnects a call, Symposium TAPI SP sends a
disconnected call state message. To clear the call, Microsoft TAPI must also drop
the call, by invoking the lineDrop command. This command causes Symposium
TAPI SP to change the call state to idle.
