150-712-200-02 Overview
HRE-712 List 1 and List 2 July 26, 2000 1
OVERVIEW
This document describes and provides installation instructions for the following HiGain®Remote Enclosures:
•HRE-712 List 1 (gel filled)
•HRE-712 List 2 (air filled)
FEATURES
•Aluminum card cage enclosure for up to 12 doublers. Each doubler slot’s pair assignments are shown in
Table 1 on page 15. See also “Card Cage” on page 19.
•Unique card guides that automatically adapt to accommodate the following form factors:
–Full T1 (1.544 Mbps) doublers: HDU-437 and HDU-407 (Digital Data Service [DDS] mechanics),
HDU-439 (dual 239 T1 mechanics) or HDU-409 (single T1 mechanics)
–Fractional T1 (772 Mbps) doublers: HDU-217 (DDS mechanics) or HDU-219 (dual 239 T1 mechanics)
–239 T1 repeaters
–Integrated Services Digital Network (ISDN) repeaters
•30-foot (9.1 m), gel-filled or air-filled, 52-pair cable stubs
•Front leading profile for underground HRE-712 List 2 and standard vertical mounting for HRE-712 List 1 for
aboveground applications.
•Primary surge protection
•Seamless, stainless steel cover that maintains weathertight integrity and provides efficient heat exchange to
expel the heat generated within the HRE-712.
•HRE-712 List 2 has a stainless steel composite baseplate for the HRE-712 List 2 for easy replacement when
used as a 4-slot HRE-454.
APPLICATIONS
The primary application of the HRE-712 is to house HiGain doubler units in an HDSL T1 transmission system. It
is designed to protect HiGain doubler units from potentially harmful conditions found in outdoor environments.
•The HRE-712 List 1, shown in Figure 1 on page 2, contains a gel-core stub and is intended for aboveground
applications that do not require pressurization through the cable stub.If youprefer to pressurize the enclosure,
it can be locally pressurized using an optional pressure-relief valve.
•The HRE-712 List 2, shown in Figure 2 on page 3, contains an air-core stub and 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 enclosure models are
similar in that they have primary gas-tube surge protection on all cable pairs. In addition, if you prefer not to
pressurize the enclosure, you can use the optional breather-vent to allow it to breathe.

HRE-712 List 1 Gel-Filled Stub
The gel-filled cable stub on the HRE-712 List 1, shown in Figure 1, is equivalent to an ALP FTS-PIC, filled-core
telephone cable. Table 2 on page 24 provides a description of the cable stub. The enclosure 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 HRE-712 List 1 enclosure is equipped with three metal valves installed in the base section, shown in Figure 1.
The breather-vent assembly allows the circulation of outside air through the HRE-712 List 1 enclosure when it is
not pressurized. The enclosure must breathe to prevent excess moisture and other damaging contaminants from
accumulating within the enclosure.
An optional external pressure-relief valve is included in the shipping kit for the HRE-712 List 1. Use the valve in
place of the breather-vent assembly when sealing the enclosure for underground applications, or when locally
pressurizing the HRE-712 List 1.
The combinedSchrader air-stem and External AirIntake T-valve, shown in Figure 1, has both aSchrader air valve
and an air intake port that accepts a tube for connection to an external air source. In addition, the Schrader valve
can relieve the internal pressure of the dome when using an external air source. The external source must be able
to be turned off upstream from the air intake port.
“HRE-712 List 1 Vented-to-Pressurized Conversion Procedure” on page 22 provides instructions on converting
the enclosure to a pressurized enclosure. The Pressure Cutoff valve allows the external source of air to be cut off
when the cover is to be removed.

The gel-filled cable complies with the requirements of ANSI/ICEA S-84-608-1994 and REA
PE-89.
