Command Description Options
Ln Line Loopback (LLB): This option tests the network line from the far-end
node. With Line Loopbacks, incoming signals are looped around and sent
back toward the network. The service provider or far-end node administrator
can then determine if the network line is good.
1) DEACTIVATE
2) ACTIVATE
Pn Payload Loopback (PLB): This option tests the QPRI from the far-end node. In
this case, the data goes through the network line and the QPRI framer before
it is looped back toward the network.
1) DEACTIVATE
2) ACTIVATE
Rn Local Loopback (RLB): This option tests all of the QPRI. Also known as a
Repeater Loopback, the data sent from the data equipment passes through
the QPRI up to the network interface and back to the equipment without
passing through the network line.
1) DEACTIVATE
2) ACTIVATE
