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.
