Starting a Payload Loopback

The Payload Loopback command (PLB) loops the received signal on the network

interface back to the network. The signal is looped back as close to the DTE

Drop/Insert (DSX-1) port as possible (after it has passed through the framing

circuitry of the DSU/CSU). Framing CRCs and BPVs are corrected.
