I have a point to point T3 circuit from routerA to routerB. To the best of my knowledge, I understand that there are three different types of framing for the circuit (M13, Cbit, and Unframed). What are each framing type used for? What are the difference between the three? One of my T3 circuit used the Cbit framing type and it took thousands of input errors and carrier transistions per day. We tried everything under the sun to find a solution, but still could not figure out the problem. We contacted the provider and told them to change the circuit to unframed and the problem cleared! Very strange. Thanks in advance.
I have this problem too.
