  • Page 16: Loopback Operation

    Loopback Operation OOPBACK When equipped with the EDU-409 List 1, a HiGain system can execute a number of loopback commands. The loopbacks can be initiated from the ELU craft port or from the ELU front-panel buttons. For more information about doubler loopback commands, refer to the appropriate ELU practices All NDU loopbacks are towards the network.
  • Page 17: Functional Description

    The doubler unit power supply uses the HDSL simplified line voltage to produce +5 Vdc and +3 Vdc required by the EDU-409 List 1 electronics. The power feed is passed on to the HDSL output pair, to power a second doubler or a remote unit.

    AULTS ROUND AULT The EDU-409 List 1 has ground fault detection (GFD) circuits. When used with HiGain line units, ground faults occurring at any point along any span are immediately detected. Ground fault conditions shut the HiGain circuit down. The line unit periodically tries to apply power to the first span to determine whether the fault condition is still present.
