Parameters
up up-seconds: Specifies the time (in seconds) within which the PVC comes up if no AIS/RDI alarm cells
are received. The value range for the up-seconds argument is 3 to 60 seconds.
down down-seconds: Specifies the time (in seconds) within which the PVC goes down if it receives
successive AIS/RDI alarm cells. The value range for the down-seconds argument is 1 to 60 seconds.
Usage guidelines
The system uses a timer to detect AIS/RDI alarm cells received in the last one second:
• A PVC goes down if it receives successive AIS/RDI alarm cells in the time period specified by the
down-seconds argument.
• A PVC comes up if no AIS/RDI alarm cells are received in the time period specified by the
up-seconds argument.
Examples
# Configure the AIS/RDI alarm detection parameters for PVC 1/32, setting up-seconds to 5 and
down-seconds to 5.
