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.
