Definition
While on-hook, this is the maximum time period that the IP
endpoint expends attempting to register with its current
Communication Manager server (Gateway). The need for this
timer arises in situations where the current Communication
Manager server may have a large number of C-LAN circuit
packs. This timer allows the customer to specify the maximum
time that an IP endpoint spends on trying to connect to the C-
LANs associated with the current Gateway before going to an
LSP as defined in the
While off-hook, the endpoint continues trying to re-establish
connection with the current server (Gateway) until the call ends.
on page 146 lists the sequence of events during recovery and
on page 148.
Description
Link failure detected (any of the following):
• Gateway detects a TCP socket failure
• TCP socket closure
• Catastrophic network error on the link
• Lack of a TCP Keep-Alive signal from the endpoint (Keep-Alive Count
exceeded). See Keep-Alive signals
signals not acknowledged by Gateway,
Alternate Gateway List.
