loopback local

Loops the incoming receive signal back out to the transmitter. You can specify whether to use the line or payload.

local line

local payload

Loops the incoming signal back in the interface module using the payload loopback mode of the framer. The framer reclocks and reframes the incoming data before sending it back out to the network. When in payload loopback mode, an all 1s data pattern is received by the local HDLC receiver and the clock source is automatically set to line (overriding the clock source command). When the payload loopback is ended, the clock source returns to the last setting selected by the clock source command.

loopback remote iboc
