ASAI Maintenance Capabilities
11-4 Issue 7 May 1998
Considerations
The Suspend Alarms capability overrides any administered alarms and halts
periodic ECS maintenance for the particular ASAI interface over which it is
received.
When alarms are suspended on a link, the ECS continues to service that ASAI
link as follows:
■ The ECS continues to send periodic Heartbeat requests on any link that
has suspended alarms, but does not raise alarms or attempt to re-initialize
the link if there is no response to a Heartbeat request.
■ The ECS continues to process ASAI associations that are in progress.
■ The ECS accepts and processes requests for new ASAI associations.
Transmitting a Suspend Alarms on an ASAI link does not affect any associations
in progress on the link. This allows any remaining associations to terminate
gracefully. New associations may be initiated when alarms are suspended. Note
that if the ASAI port/station is busied out after having suspended alarms, the
alarms will be resumed upon the release of ASAI port/status.
Resume Alarms
This capability enables the adjunct to resume the ECS alarms on an ASAI link.
Information Flow
The adjunct makes the suspend alarms request.
The ECS issues an ACK to notify the adjunct that it will raise alarms for the ASAI
link.
