The Hotwire 7974 Standalone Termination Unit supports line loopback as
specified in AT&T TR 54016, AT&T TR 62411, and ANSI T1.403. A Telco-initiated
line loopback loops the received signal on the DSX-1 interface back to the DSX-1
interface without modification. Framing, CRC, and FDL bits are returned
unaltered, and no BPVs or other line coding errors are removed.
