Keep-Alive Feature

T-Server may not always receive timely notification when the CTI link stops functioning. In order for T-Server to detect link failure and initialize alarm and recovery procedures, T-Server usually needs to actively check the link's integrity. This is referred to as Keep-Alive or KPL functionality.

Keep-alive functionality involves sending a KPL request which elicits either a positive or negative response from the CTI link. The responses are counted in four cumulative counters. If the relevant counter reaches the maximum configured limit, T-Server either:

• Decrements the relevant warning/failure KPL tolerance counter
• Attempts to reconnect to the link
• Sends a warning message to Message Server
