Thanks. So from this I can see that the Link in the last 24 hours has been fully usable, which would not indicate any errors on the link itself.
I can see why the Maintainer suggested that this is a carrier issues, as it does indicate a far end alarm.
With the information you provided I would have to agree. There are no indications, that this is a fault with the hardware / software.
However, If you have access to the 3300 can you monitor the link light on the Framer, and tell us what happens. If the link light goes from green to yellow consistantly, then I would replace the cabling from the 3300 to the NTE and if not then that would be a good place to start anyway.
