I have a T1 plugged directly into a dialogic card configured for ami/d4 and telco states their seeing b8zs signals. They've taken the ckt down and tested clean to csu. The telco indicates that the equipment is configured for b8zs/esf but it isn't. I've reconfigured the equipment again for ami/d4. What could be causing this? (the csu was disconnected from ckt to exclude this as a possibility)
Thanks in advance.
