HP 3162 Starting a Repeater Loopback

Monitoring and Testing

Starting a Repeater Loopback

The Repeater Loopback command (RLB) loops the signal being sent to the network back to the DTE Drop/Insert (DSX-1) and data ports. The signal is looped back as close to the network interface as possible (after it has passed through the framing circuitry of the DSU/CSU). Framing CRCs and BPVs are corrected.
