Loopback Type Definition

Payload Loopback (PLB) A PLB loops the signal intended for the DTE back

toward the far-end at the data port. It tests the

T1 channels and the IMUX module up to the data

port.

Equipment Loopback (ELB) When used with an M1-3, the DTE signal is

looped back to the DTE. This test isolates the

equipment cable and DTE as possible trouble

locations.
