Possible Problem
The port on the
reporting node is
in-service but a node
upstream on the circuit
does not have an OC-N
port in service.

Clear AIS-V on DS3XM-6 Unused VT Circuits

Note This procedure does not apply to Software R4.6 DWDM cards or ML-Series cards.
Step 1 Determine the affected port.
Record the node ID, slot number, port number, or VT number.
Step 2
Create a unidirectional VT circuit from the affected port back to itself, such as Source node/
Step 3
Slot 2/Port 2/VT 13 cross connected to Source node/Slot 2/Port 2/VT 13.
Uncheck the bidirectional check box in the circuit creation window.
Step 4
Give the unidirectional VT circuit an easily recognizable name, such as "delete me."
Step 5
Display the DS3XM-6 card in CTC card view. Click the Maintenance > DS1 tabs.
Step 6
Locate the VT that is reporting the alarm (for example, DS3 #2, DS1 #13).
Step 7
From the Loopback Type list, choose Facility (Line) and click Apply.
Step 8
Click Circuits.
Step 9
Find the one-way circuit you created in
Step 10
Step 11 Click Yes in the Delete Confirmation dialog box.
Step 12 Display the DS3XM-6 card in CTC card view. Click Maintenance > DS1.
Step 13 Locate the VT in Facility (line) Loopback.
Step 14 From the Loopback Type list, choose None and then click Apply.
Step 15 Click the Alarms tab and verify that the AIS-V alarms have cleared.
Step 16 Repeat this procedure for all the AIS-V alarms on the DS3XM-6 cards.

Solution
An AIS-V indicates that an upstream failure occurred at the virtual tributary
(VT) layer. AIS-V alarms also occur on DS3XM-6 VT circuits that are not
carrying traffic and on stranded bandwidth.
