MSDL card disabling

[lanrucj]

one of our msdl cards is disabling. here is the error i get. is there a specific type of message it is referring to that is causing the msdl card to go out of service, in turn disabling d-channels associated with it.

BUG5570

The MSDL/MISP sent a "message" to the SL-1 indicating that it received a message with a format error. There are either three or four fields

output with this message:

1. The MSDL card number or the MISP loop number,
2. The type of formatting error (value of 0: unknown or unexpected message, value of 1: invalid message length),
3. The message id of the "bad" message, and
4. If the formatting error type was message length, the length of the actual message.

During a maintenance window you might disable all applications that use that card and then disable the MSDL card. Re-enable it with a force download and then monitor. If it continues to fail, replace the card.

we did do the download and i believe we recently replaced the card.

what if the cause is the incoming message? is there something other than the download and replacing the card we can try.

thanks

Hmm. I did a lookup on Knowledge Base for BUG5570 and it came back with nothing. What all do you have working off that card? Only d-channels? I wonder if one of the d-channels on the card is causing it? Did this problem occur suddenly after working properly for a long period of time? What if you took a 2nd card and installed it into the system and split the existing d-channels between both cards? If the problem stays with the original card, frog the d-channels and see if the problem moves to the 2nd card. If it does, then you can narrow down which d-channel is the culprit.
