physical framing errors on layer 2 on provider side.
Basically, in the SAT I can see errors in the board 1v4.

According to the alarm guide, the two error type regarding DS1 card means the followings:
1. 2305: Yellow alarms, which means the DS1 board notifies the remote card is in out-of-frame status, there can be some physical-framing error:
2. 3585: Misframe alarm, according to it, the CM received corrupted data frames. This can be due to some Layer 2-switching problems somewhere in the network (in the provider side as well)
I have checked the GW logs again, and found these error messages relatively often:

In the ECS logs:

These entries are about the DS1 board in the slot 1v4. That means, the DS1 MM710 card received yellow alarms, that the remote DS1 has errors, and the CM started to reinitialize the card.
