fdl-ansi-llb-down: Sends ANSI-compliant LLB deactivation request code in the
FDL to removes loopback.
fdl-ansi-llb-up: Sends ANSI-compliant line loopback (LLB) activation request code
in the FDL to start remote loopback.
fdl-ansi-plb-down: Sends ANSI-compliant PLB deactivation request code in the
FDL to remove loopback.
fdl-ansi-plb-up: Sends ANSI-compliant payload loopback (PLB) activation request
code in the FDL to start remote loopback.
fdl-att-plb-down: Sends AT&T-complaint PLB deactivation request code in the
FDL to remove loopback.
fdl-att-plb-up: Sends AT&T-complaint PLB activation request code in the FDL to
start remote loopback.
inband-llb-down: Sends in-band LLB deactivation request code compliant with
the ANSI or AT&T implementation to remove loopback.
inband-llb-up: Sends in-band line loopback (LLB) activation request code
compliant with the ANSI or AT&T implementation to start remote loopback.
Use the
ft1 sendloopcode
By default, no remote loopback control code is sent.
You may configure loopback on the far-end T1-F interface by sending loopback
request code.
In LLB mode, all 193 bits (one synchronization bit and 192 effective bandwidth
bits) in a T1 PCM frame are looped back. In PLB mode, however, only 192 effective
bandwidth bits are looped back.
