5.1 T1 loopbacks

The T1 interfaces support local and line (network) loopbacks:

• During a line (network) loopback, the signal is looped back to the network. The receive T1 signal is looped onto the transmit T1within the framer chip.

• During a local loopback, the signal is looped back to the user. The transmit T1 signal is looped onto the receive T1within the LIU.

The Z-Plex unit supports ESF loopback detection sent from remote equipment. These codes are ANSI T1.403 compatible with DS1 networks and allow the unit to detect a latching loopback to remote DS1 equipment. The Z-Plex detects payload loopback (PLB), network loopback (NLB), and line loopback (LLB). The Z-Plex also supports TR 54016 for loop up and loop down cases.

Figure 5-1 on page 5-2illustrates T1 loopbacks on the Z-Plex unit.
