No active loopback.

LOCAL LOOPBACK

Activates both a local loopback (back toward the DTE) and a port

 

loopback (toward the network).

REMOTE LOOPBACK

V.54 loopback code to be sent to the far end, and if the device at the far

 

end supports V.54, the device activates a loopback on detection of the

 

V.54 code.
