We have a very strange situation that we cannot explain. We have a couple of 3845 with 8xE1's connected to each. We have been informed from the carrier that they are getting fast busy and no network.
The strange part behind it is, that they are only getting busy on certain channels for the E1's. As an example -
1/1 - Channels 2, 12 and 20 is busy
1/0/0 - Channels 3, 14 and 22 busy
2/1 - Channels 5 and 19 busy....
The other channels are fine and the line/signal is up....
Would anyone have a clue or be able to help us out with something to look at???
