Page 9: Overview
Overview VERVIEW ® ® The PairGain HiGain Remote Unit Model HRU-412 List 6 is the remote end of a repeaterless T1 transmission system. An HRU-412 List 6 connects to a HiGain Line Unit (HLU), creating a HiGain system which provides 1.544 Mbps transmission on two unconditioned copper pairs over the full Carrier Service Area (CSA) range. -
Page 10: Applications
Applications 150-412-106-06, Revision 06 PPLICATIONS 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 wire pairs. The HiGain system can be deployed on two unconditioned, non-loaded copper wire pairs without repeaters, and without the need for bridged tap removal or binder group separation. -
Page 11: Functional Description
This section describes the functions of the HRU-412 List 6. PERATIONAL APABILITIES HiGain utilizes PairGain’s 2B1Q HDSL transceiver system to establish two full-duplex 784 kbps data channels between the HLU and a remotely mounted HRU-412 List 6. This provides a total transmission capacity of 1.568 Mbps between the two units. -
