Make sure your E1 is setup correctly, framing, signaling, protocol, and clocking. Or check with Nortel if a recall exists on your DTI mod, and most important make sure BCM is running latest patches. If you have a E1 tester do a none-intrusive testing on the span, could be a channel bank issue. Arrange a meet with your local Telco CO to fix - Good Luck!

nice description sounds like framing errors to me, you need to get a trend tester on the circuit..
