Specifying Alternate Tlinks for the TSAPI Windows client

Last Updated : Aug 28, 2026 |
Prolog information
The Alternate Tlinks feature enables the TSAPI client library to select an alternate Tlink if the preferred Tlink is unavailable when trying to establish a session. To enable the usage of this feature, specify the alternate Tlinks in the TSAPI Configuration file. For more information, see TSAPI Links (Tlinks).
Important:
When multiple AE Services Servers are used as alternates, the CT User user ID, and password used by the application must be configured identically on each AE Services Server.
Use this procedure to set up a list of alternate Tlinks in the tslib.ini file. You are typically adding statements that specify a list of alternate Tlinks for the TSAPI Service.
  1. Click on Start All ProgramsAvaya AE ServicesTSAPI ClientEdit TSLIB.INI to open the tslib.ini file.

    ADDITIONAL INFORMATION:
    This line is required if you want your TSAPI Windows clients to use the Alternate Tlinks feature.
  3. After the [Alternate Tlinks] line, add a list of alternate Tlink entries.
