    150-412-181-01 March 31, 1998 Revision 01 VERVIEW ® ® The PairGain HiGain Remote Unit Model HRU-412 List 8A is the remote end of a repeaterless T1 transmission system. An HRU-412 List 8A connects to a HiGain Line Unit (HLU-231, HLU-232, HLU-319, or HLU-388), creating a HiGain system which provides 1.544 Mbps transmission on two unconditioned copper pairs over the full Carrier Serving Area (CSA) range.
  • Page 8 Revision 01 March 31, 1998 150-412-181-01 • Lightning and power cross protection on HDSL and DS1 interfaces • 784kbps full-duplex 2B1Q HDSL transmission on two pairs • DS0 blocking support The HRU-412 List 8A supports PairGain’s 1 x 1 Protection Switching System.

  • Page 9: Applications

    150-412-181-01 March 31, 1998 Revision 01 Applications A HiGain system, consisting of a HiGain line unit and a HiGain remote unit, provides a quick and cost-effective way of delivering T1 High Capacity Digital Service (HCDS) to customers over copper pairs. The HiGain system can be deployed on two unconditioned, non-loaded copper pairs without repeaters, and without the need for bridged tap removal or binder group separation.

  • Page 19 150-412-181-01 March 31, 1998 Revision 01 If local power is lost to an HRU-412 List 8A, the last span loses sync. When the HLU or HDU attempts to reestablish sync, it detects that the HRU-412 List 8A is not locally powered and applies line power to it. The HRU-412 List 8A then powers up and operates normally if the HRU-412 List 8A is within range to support line powering.
