150-458-100-05 Overview
HRE-458 List 1, List 1B, and List 2 February 23, 2000 1
OVERVIEW
This document describes the HiGain®Remote Therm-O-Nator HRE-458 gel-filled (List 1, List 1B) and air-filled
(List 2) enclosures and provides installation instructions for these enclosures.
FEATURES
The following features are included on the HRE-458 HiGain Remote Therm-O-Nator enclosure:
•Ten doubler card slots that support:
–HDU-437 and HDU-407 (DDS Mechanics), HDU-439 (Dual 239 T1 Mechanics), and HDU-409 (Single
T1 Mechanics) Full T1 doublers
–HDU-217 (DDS Mechanics) and HDU-219 (Dual 239 T1 Mechanics) Fractional T1 doublers
–HDU-239 T1 repeaters
•30-foot (9.144 m), gel-filled or air-filled, 52-pair cable stub
•Flat surface, rack, or pole mount
•Primary surge protection
•Seamless, stainless steel cover with Therm-O-Nator heat exchange unit
•Single stub access
•Tilt forward mounting
•Unique card guides that automatically adapt to accommodate any of the three mechanics form factors
currently supported
APPLICATIONS
The primary application of the HRE-458 is to house HiGain doubler units in a High-bit-rate Digital Subscriber
Line (HDSL) T1 transmission system. The remote enclosure is designed to protect HiGain doubler units from
potentially harmful conditions found in outdoor environments. The enclosure comes in either a single gel core stub
(List 1, List 1B) or air core stub (List 2) unit.
The HRE-458 gel core List 1, List 1B unit is intended for aboveground, pole-mounting applications that do not
require pressurization through the cable stub. However, if you prefer to pressurize the unit, it can be locally
pressurized by an optional exterior air cutoff valve (see Figure 2 on page 4). The HRE-458 air core List 2 unit is
intended for underground installations. It can be pressurized from the main feeder cable through its air core stub.
The pressurization prevents the enclosure from flooding when mounted in underground manholes. Both units are
similar in that they have primary gas tube surge protection on all cable pairs.
The HRE-458 can be used to house the following doubler and repeater units. All of these doublers and repeaters
share the same generic slot pin assignments as shown in Table 2 on page 15.
•HDU-439, HDU-437, HDU-409, or HDU-407 Full T1 (1.544 Mbps) unit
•HDU-219 or HDU-217 Fractional T1 (772 Mbps) unit
•ISDN repeater
•DDS repeater
•239 T1 repeater

FUNCTIONAL DESCRIPTION
The following section discusses the function of each component on the HRE-458. The enclosure consists of an
aluminum card cage with a holding capacity for up to ten doubler units, a stainless steel composite baseplate, and
a stainless steel cover that maintains weathertight integrity and provides efficient heat exchange to expel the heat
generated within the units.
Gel-filled Stub Unit
The gel-filled cable stub on the List 1, List 1B unit (Figure 1) is equivalent to an ALP FTS-PIC filled core
telephone cable (refer to Table 5 on page 27 for a complete description of the cable stub). The unit is intended for
aboveground applications. Standard color codes are used for pair identification with color compounds chosen for
electrical balance and permanency. An inner core jacket protects the core and provides improved mechanical and
electrical characteristics. The outer jacket consists of material that provides protective covering from sunlight,
atmospheric temperatures, ground chemicals, and stresses expected in standard installations.
The gel-filled List 1, List 1B unit is similar to the air-filled List 2 unit except that a breather vent valve on the List
1, List 1B replaces the internal pressure cutoff valve on List 2. The breather vent valve allows the circulation of
outside air through the List 1, List 1B enclosure when it is not pressurized. The enclosure must breathe to prevent
the buildup of excessive moisture and other damaging contaminants from occurring within the enclosure.
An optional pressure relief valve is included in the shipping kit for the List 1, List 1B unit. The kit comes in a
small plastic bag that is attached to the brown/white spare pair shrink tab. Use the pressure relief valve in place of
the breather vent valve to locally pressurize the List 1, List 1B unit. See page 24 for conversion details.

The cable complies with the requirements of the American National Standards Institute
(ANSI) and the Insulated Cable Engineers Association (ICEA) S-84-608-1994 and REA
PE-89, respectively.
