LTPH-TP-1024-02, Issue 2 Overview
HRU-402 List 4 January 3, 2001 1
OVERVIEW
The ADC®HiGain®Remote Unit, HRU-402, functions as the remote end of
a repeaterless T1 transmission system. When used with HiGain Line Units
(HLUs) and HiGain Doubler Units (HDUs), the HiGain system provides
1.544 Mbps data transfer on two unconditioned copper pairs over the full
Carrier Service Area (CSA) range.
In addition to HiGain Maintenance Terminal screens, the HRU-402 List 4
provides special performance monitoring and sectionalized analysis
information for fault isolation. This performance monitoring feature supports
real-time and on-demand reporting.
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 and the remote unit is housed in a remote enclosure at the
Customer Premises Equipment (CPE)site.OptionalHDUsprovidetheability
to double or even triple the distance range for customer applications located
outside the CSA.
