• Added: PVCR Link Management for point-to-point applications using T1/E1
card interfaces has been improved, and physical alarms are now propagated from
one side of the network to the other. The current status can be displayed with the
new Display Link State (DLS) command.
To reflect the digital card interface alarm conditions end to end, the host monitors
the status of the PVCR link, and the Signaling Engine monitors the status of the
physical port on the card. An alarm is logged when either status changes, based
on the current value of the LINK parameter Link management alarm type, which
can be set to RAI/ YELLOW or AIS.
Host-side link management will work only if both sides of the connection are
installed with NetPerformer V10.4.1 R01.
PVCR link management alarms that are now sent end to end include:
- RAI: Remote Alarm Indication for E1, Yellow Alarm for T1
- AIS: Alarm Indication Signal
- LOF: Loss of Frame
- LOS: Loss of Signal
- TS16AIS: Timeslot-16 Alarm Indication Signal, for E1-CAS only
- LOMF: Loss of Multiframe, for E1-CAS only
The Display Link Status (DLS) Command
To execute the Display Link Status command, enter DLS at the NetPerformer
console command line. Use the left and right arrow keys to change from one slot
to another. Press K to access a list of other navigation keys.
The DLS display provides quick access to information about the two primary
objects of interest for link management:
- [ LOCAL INTERFACE ]: The local interface that is being monitored. Information
includes:
� The monitored interface (link) number, e.g: 0100
� The current state of the interface, including both physical
conditions like DISABLED and Link Management alarms such as
NO ALARM, TX AIS, RX RAI
For example, you can easily see that the interface has received an RAI alarm,
transmitted an AIS alarm, or is simply disabled.
