Local Loopback The USSI port activates both a local loopback (back to-
ward the DTE) and a port loopback when invoked.
Remote Loopback The remote loopback causes a V.54 loopback code to be
sent to the far end. If the device at the far end supports
V.54, the device activates a loopback on detection of the
V.54 code.
