Call Watch Mode - HP FlexNetwork MSR Series Configuration Manual

•
If local interfaces are monitored, the E1/T1 interface is set to watch-out state when all the
monitored local interfaces are down.
•
If IP connectivity to remote interfaces is monitored, the E1/T1 interface is set to watch-out state
when all the monitored remote IP addresses are unreachable.

Call watch mode

A call watch group can operate in hard or soft mode on an E1/T1 interface.
•
In soft mode, the E1/T1 interface will be set to watch-out state after all the monitored links are
detected unavailable only if no calls are present on the interface.
•
In hard mode, the E1/T1 interface is set to watch-out state immediately after all the monitored
links are detected unavailable regardless of whether calls are present on the interface.

Configuring call watch for an E1/T1 interface
Configuring call watch for an E1/T1 interface includes these tasks:
Configuring a call watch group
•
Associating the E1/T1 interface with the call watch group
•
Configuring a call watch group
Configuring a call watch group creates the call watch rules in the group. To monitor the IP
connectivity to remote interfaces, a call watch group must collaborate with the NQA and Track
modules. Thus, configure the remote IP addresses to be monitored with NQA, and configure the
Track function to work with NQA to send probe messages to the call watch group. In a call watch
group, the rule for monitoring a remote interface is the track object ID associated with the interface.
You can create up to 255 call watch groups on each voice device.
You can configure a call watch group to monitor up to 16 local interfaces or remote IP addresses.
For more information about configuring the NQA function, see HPE FlexNetwork MSR Router Series
Comware 5 Network Management and Monitoring Configuration Guide.

Series Comware 5 High Availability Configuration Guide.
