Attribute Description
LCP Keep Alive Interval This parameter determines the how long the Business Communications Manager waits
before determining that the WAN link is not functioning.
When there is no regular traffic on the WAN link, the Business Communications Manager
sends an echo packet out on the link. If there is no response within the LCP Keep Alive
Interval, the Business Communications Manager sends another echo packet. If there is no
response after 10 echo packets, the Business Communications Manager determines that
the link is down. If there is a response to any of the echo packets, the Business
Communications Manager determines that the WAN link is functioning.
Enter the LCP Keep Alive Interval, in seconds, that the Business Communications
Manager waits between sending echo packets.
The default value is 10 seconds.
LQR Interval Enter the interval, in 1/100 second, to perform link quality monitoring.
