Network Interface Loopbacks

Network interface loopbacks affect the entire T1 data stream. See Figure 7-2. The two types of network loop- backs are:

Line

Loops all of the received data back toward the network. The transmitted data is the identical line code that was received, including any bipolar violations or framing errors.

Payload

Similar to line loopback, except that the framing is extracted from the received data and then regenerated for the transmitted data.
