0x000F Link Down Timer

This timer is used when the link between the IP Signaling Series 3 Card and the CSP Matrix Series 3 Card goes down. If there is a secondary CSP Matrix Series 3 Card present in the node, the IP Signaling Series 3 card triggers this timer and does not release any active calls (calls in the answered state). The IP Signaling Series 3 card waits until the timer expires to re-establish the connection with the secondary matrix.

If the connection is re-established, all the active calls stay connected; however, no new calls (incoming or outgoing) can be made when the link between the CSP Matrix Series 3 Card and IP Signaling Series 3 card is temporarily down.

If the link is not re-established or if there is no secondary CSP Matrix Series 3 Card in the node, all of the active calls are released on the H.323 (IP) end.

Used in:
IP Signaling Series 3 Card Configure message
IP Signaling Series 3 Card Query message
