Network Interface Loopbacks

Network interface loopbacks affect the entire T1 data stream. There are two types of network loopbacks: line loopback and payload loopback.

Line loopback loops all of the received data back toward the network. The transmitted data is the identical line code that was received, includ- ing any bipolar violations or framing errors.

Payload loopback is similar to line loopback, except that the framing is extracted from the received data and then regenerated for the transmit- ted data.
