150-204-111-01, Revision 01 Overview
HRE-204 List 1A and List 2A April 7, 2000 1
OVERVIEW
This document describes the PairGain®HiGain®Remote Enclosure HRE-204 List 1A and List 2A that houses
HiGain Line Units (HLUs) and remote units (HRUs). The HRE-204 List 1A has RJ48C DS1 connectors, and the
HRE-204 List 2A has RJ48X connectors.
FEATURES
The HRE-204 List 1A and List 2A provide the following features:
•four 200-mechanics or two 400-mechanics slots
•RJ48C (List 1A) or RJ48X (List 2A) modular jack for DS1 customer interface connections
•printed-circuit backplane with terminal block and RJ48 connectors
•tamper-proof locking screw for security
•48 V input power for HLU applications
•separate input terminals for slot isolation
•wall or desktop mounting
•optional wall-hinge mount
•pre-painted, cold-rolled, #16 gauge steel construction
APPLICATIONS
HiGain provides a quick and cost-effective way of delivering T1 High Capacity Digital Service (HCDS) to
customers over metallic cable pairs. The HRE-204 houses units for a HiGain repeaterless T1 transmission system.
The HRE-204 List 1A and List 2A uses standard 200-mechanics and 400-mechanics slots
and can accommodate any plug with 200-mechanics or 400-mechanics, including the
HiGain HRU-402 (HDSL) and H2TU-R-402 (HDSL2) remote units, and the HLU-432 (HDSL)
line unit.
Since the HRE-204 supports chassis ground to pin 27, it is not compatible with PairGain
legacy HDSL HRU-412 remotes that only use pin 1 for chassis ground.
The HRE-204 provides a chassis ground connection to pin 27 only in every slot.
