Default command level
2: System level
Parameters
watch-number: Specifies a call-watch group number in the range of 1 to 255.
hard: Specifies the call-watch mode as hard. In hard call-watch mode, the E1/T1 interface is set to
watch-out state as soon as all the monitored links are detected unavailable regardless of whether calls
are present on the interface. An interface in watch-out state does not respond to calls initiated by the
connected PBX.
soft: Specifies the call-watch mode as soft. In soft call-watch mode, the E1/T1 interface is set to the
watch-out state after all the monitored links are detected unavailable only if no calls are present on the
interface.
Usage guidelines
You can associate an E1/T1 interface with only one call-watch group, and vice versa.
You can associate an E1/T1 interface with a call-watch group that has not been created yet but the
configuration does not take effect.
Examples
# Associate interface E1 1/0 with monitor group 1 in soft mode.
<Sysname> system-view
[Sysname] controller e1 1/0
[Sysname-E1 1/0] call-watch group 1 soft
