DTE Loopback

DTE Loopback loops the DSX-1 or G.703 signal back to itself before the signal is sent to the Framer. Also, for DSX-1 models:

HIf the DSX-1 port is in a DS0 cross-connection, corresponding DSL time slots are sent all ones.

HIf the DSX-1 port is in Bypass mode or a DS1 cross-connection, all ones are sent to the corresponding DSL port and data received on the DSL link is ignored.
