Figure 21: Keep-Alive signals not acknowledged by Gateway
Table 53, Administrable H.323 Link Bounce Recovery parameters,
on page 145 lists the administrable
parameters that interact within the H.323 Link Bounce Recovery feature. See
for how to
implement these parameters.

Table 53: Administrable H.323 Link Bounce Recovery parameters
Parameter
(device)
Definition
Idle Traffic Interval
(Endpoint)
The maximum traffic idle time after which a TCP Keep-Alive
(KA) signal is sent from the endpoint.
Keep Alive Interval
(Endpoint)
The time interval between TCP Keep-Alive re-transmissions.
When no ACK is received for all retry attempts, the local TCP
stack ends the TCP session and the associated socket is closed.
Keep-Alive Count
(Endpoint)
The number of times the Keep-Alive message is transmitted if no
ACK is received from the peer.
H.323 Link Loss Delay Timer
(Gateway)
This timer specifies how long the Communications Manager
server (Gateway) preserves registration and any stable calls that
may exist on the endpoint after it has lost the call signaling
channel to the endpoint. If the endpoint does not re-establish
connection within this period, Communication Manager tears
down the registration and calls (if any) of the endpoint.
NOTE:
This timer does not apply to Soft-endpoint
telecommuter calls.
