To recover from this situation, perform a manual restart or disable the ALS in this configuration. This
issue will not be resolved.

When downloading Release 4.7 nodes with Release 4.6 installed, The 15454-32MUX-O and
15454-32DMX-O report an AWG Temperature fail low alarm that subsequently clears. This also occurs
when downgrading from Release 4.7 to Release 4.6, where the AWG Temperature alarm fail is high. This
issue cannot be resolved.

AS-MT is not enabled in Port 3 when a loopback is applied. To see this issue, on the TXPP card, make
the following 3 changes before clicking Apply:
Step 1 Change Port 2 to OOS-MT from IS.
Step 2 Change Port 3 to OOS-MT from IS.
Step 3 Change Port 2 to facility or terminal loopback.
Now, when you click Apply, CTC issues the error message: “Error applying changes to row2 peer trunk
port must not be IS.” Port 3 is still IS and the loopback changes are not applied. You must place Port 3
in the OOS-MT state, apply the changes, and then change the loopback to recover.
This error occurs only when all three of the above changes are attempted at the same time.
To avoid this issue, first change both the trunk ports to OOS-MT, click Apply, and then place port 2 in
loopback and click Apply again. This issue will not be resolved.
