Telco-Initiated Line Loopback

Hotwire 8747 and 8777 Termination Units support 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. DSL time slots mapped to the DSX-1 port are sent all ones.
