    Testing LTPH-UM-1149-01 ENERIC OOPBACK OMMANDS The HDSL2 Generic Loopback (GNLB) commands allows the use of inband codes to loop up either NLOC (4-in-7) or NREM (3-in-7) towards the network. Additionally, these inband codes loop up CREM (6-in-7) or CLOC (5-in-7) towards the customer. Either loopup condition can be terminated (looped down) with the 3-in-5, SMJK loopdown code.

The H2TU-C can be configured from the maintenance terminal Monitor screen using the Config menu and Special Loopback Mode option. Once a loopback mode is activated, other loopback commands can be sent by a test set connected to the craft port of the H2TU-C or H2TU-R.

    UNCTIONAL PERATION ADC HDSL2 technology provides full-duplex services at standard DS1 rates over copper wires between an H2TU-C and an H2TU-R, which comprise one HDSL2 system. ADC systems use ADC Overlapped Pulse Amplitude Modulation (OPAM) transceiver systems to establish a full-duplex, 1.552 kbps data channel between an H2TU-C and a remotely located H2TU-R.
