OVERVIEW
This user manual describes the HiGain®Remote Unit, Model HRU-402 List
1A. This remote unit functions as the remote end of a repeaterless T1
transmission system. An HRU-402 connects either to a HiGain Line Unit
(HLU) or a HiGain Doubler Unit (HDU), creating a HiGain system that
provides 1.544 Mbps transmission on two unconditioned copper pairs over
the full Carrier Service Area (CSA) range. The HRU-402 List 1A is line
powered only.
Figure 1 shows a basic HiGain configuration for a T1 High-bit-rate Digital
Subscriber Line (HDSL) circuit. The HLU is installed at the Central Office
(CO) shelf. The HRU-402 is housed in a remote enclosure at the Customer
Premises Equipment (CPE) site. Optional HDUs provide the ability to
increase the range between the HLU and HRU to four CSA spans. The total
CSA encompasses approximately 48 kft using 19 American Wire Gauge
(AWG) wire.
