150-506-100-03 Overview
HRE-506 List 1 and List 2 March 28, 2000 1
OVERVIEW
The ADC®HiGain®HRE-506 List 1 (gel-filled) and List 2 (air-filled) are outdoor, stainless steel, weatherproof
enclosures designed to house up to six HiGain remote or doubler units. The HRE-506 is part of a HiGain system.
FEATURES
The following features are included on the HRE-506 weatherproof enclosures:
•Six doubler card slots for these units:
–HDU-437 and HDU-407 (DDS Mechanics), HDU-439 (Dual 239 T1 Mechanics), HDU-409, EDU-409
(Single 239 T1 Mechanics) Full T1 doublers, or EDU-842 (DDS Mechanics/ETSI)
–HDU-217 (DDS Mechanics) or HDU-219 (Dual 239 T1 Mechanics) Fractional T1 doublers
–T1 repeaters
•30-foot (9.144 M) gel- or air-filled 28-pair cable stub
•Flat surface, rack, or pole mount
•Primary surge protection
•Seamless stainless steel cover
•Single stub access
•Tilt-forward mounting
•Unique card guides automatically adapt every slot to three mechanics
APPLICATIONS
The primary application of the HRE-506 remote enclosure is to house HiGain remote or doubler units in an
HDSL/T1 transmission system. The HRE-506 is an outdoor enclosure with six single-width mechanical slots. It
has a single gel-filled stub (HRE-506 List 1) or air-filled stub (HRE-506 List 2).
The air-filled unit can be pressurized locally or from the main feeder cable through an air core stub. This air core
stub protects the air-filled unit from flooding the water when it is mounted in underground manholes.
The gel-filled unit is intended for above ground 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 through its Air
Stem/Air Inlet T valve, as shown in Figure 1 on page 2.
Both units have primary gas-tube surge protection on all cable pairs.
The HRE-506 can house the following doubler and repeater units. All doublers and repeaters share the same
generic slot pair assignments as shown in Table 1 on page 18.
•HDU-439, HDU-437, HDU-409 or HDU-407 Full T1 unit (1.544 Mbps)
•HDU-219 or HDU-217 Fractional T1 unit (0.772 Mbps)
•EDU-842 ETSI unit (2.048 Mbps) and EDU-409 E1 unit (2.048 Mbps)
•ISDN repeater
•DDS repeater
•239 T1 repeater

PRESSURIZED APPLICATIONS
For pressurized applications on the HRE-506, the Schrader air stem valve is used. A pressure gauge attaches to
the valve for the purpose of measuring the internal pressure of the enclosure. This valve is also used to relieve the
internal pressure prior to opening and removing the dome cover. This can be done by depressing the center pin on
the valve. Figure 1 below shows the air stem valve location.
Figure 1. HRE-506 List 2 Remote Air-Filled Enclosure
Depressurizing must be performed every time the cover is removed from the enclosure. Failure
to do so may cause personal injury or damage to the equipment.

An optional breather vent assembly is enclosed in the air-filled HRE-506 List 2 shipping kit. The kit is a small
plastic bag attached to a red and brown colored spare pairs shrink tube. The breather vent replaces the
pressure-relief valve, if the air-filled unit is not pressurized. The assembly allows the enclosure to breathe and
keeps the internal atmosphere free of harmful contaminants. Figure 2 on page 3 shows the five metal valves.
Figure 2. Metal Valves
Unlike the gel-filled unit, the pressure cutoff valve in the air-filled unit cannot be used to
cut off an external air source that is applied to the Schrader air stem valve. The air-filled
unit pressure cutoff valve can only control the air source that is applied to the enclosure
through the air core stub.

FUNCTIONAL DESCRIPTION
The following section discusses the function of each component on the HRE-506. The HRE-506 consists of an
aluminum card cage with a holding capacity for up to six remote or doubler units, a stainless steel composite
baseplate, and a stainless steel cover that maintains weather-tight integrity.
Gel-Filled Unit
The gel-filled HRE-506 List 1 unit is equipped with three metal valves installed in the base section, as shown in
Figure 3on page 5. The gel-filled screened 28-pair, 24 American Wire Gauge (AWG) cable stub on the gel-filled
unit is equivalent to an ALP FTS-PIC filled-core telephone cable. The unit has foam skin insulation with a
single-filed jacket. This insulation allows the cable stub on the gel-filled unit to be used in buried, aerial, and duct
applications.
Standard color codes are used for pair identification with color compounds chosen for electrical balance and
permanency. The outer jacket provides a flexible protective covering that withstands exposure to sunlight,
atmospheric temperatures, ground chemicals, andstresses expected in standard installations.The outside diameter
of the cable is 0.64 inches (16.25 mm).
The gel-filled unit is similar to the air-filled unit, except that the gel-filled unit has a breather vent valve instead
of a pressure relief valve. The breather vent valve allows the circulation of outside air through the gel-filled
enclosure when it is not pressurized. Circulating outside air through the gel-filled enclosure prevents the buildup
of excessive moisture and other damaging contaminants within the enclosure.
A combined Schrader air stem and external air input T-valve is also included with the gel-filled units. The
Schrader air stem valve can be used to connect to an external air source or release the internal pressure whenever
the dome is removed. Opposite the Schrader valve, the external air input valve accepts tubing for connection to
an external air source. The pressure cutoff valve allows the external source of air to be cutoff, when the dome is
opened.
An optional pressure relief valve is included in the shipping kit for the gel-filled unit. The kit comes in a small
plastic bag that is attached to the shrink tab on one of the spare pairs. Use the pressure relief valve in place of the
breather vent assembly when the gel-filled unit is to be locally pressurized. For installation details, see “HRE-506
List 1 Vented to Pressurized Conversion Procedure” on page 29.
The cable complies with the requirements of the American Standards Institute (ANSI)
and the Insulated Cable Engineers Association (ICEA) S-84-608-1994 and REA PE-89,
respectively.

Air-Filled Stub Unit
The air-filled, screened, 28-pair, 24 AWG cable stub on the HRE-506 List 2 unit (Figure 1 onpage 2) is equivalent
to an ALP FTS-PIC air-core telephone cable.The unit comes with three metal valves: an air-pressure cutoff valve,
a Schrader air stem valve, and a pressure relief valve. The air cutoff valve is used to shut off the inlet air supply
that is pumped from the main feeder cable through the 30-foot (9.144 M) stub into the HRE-506 enclosure.
The air-filled stub unit is intended for buried, aerial, and duct applications. Standard colors are used for pair
identification. An inner-core jacket protects the core and provides improved mechanical and electrical
characteristics. The outer jacket provides protective covering that withstands, atmospheric temperatures, ground
chemicals, and stresses expected in standard installations. The outside diameter of the cable is 0.64 inches (16.25
mm).
The HRE-506 cable sealing, O-ring, and V-Band seal have been safely tested to 36 pounds per square inch (PSI).
Most cables become ruptured or damaged at this pressure level. However, the HRE-506 cable sealing is designed
to handle this amount of pressure.
The cable complies with the requirements of ANSI/ICEA S-85-625-1996 and REA PE-22.
Avoid using pressures above 36 PSI. Such pressures could force the V-Band away from
the flange and, in effect, impel the dome away from the housing. This could cause
damage or injury.

The common pressure supplied through the cable is approximately 9 PSI. This is sufficient to prevent water from
entering the cable or housing. ADC recommends pressurizing the enclosure to a maximum of 12 PSI.
Air-filled Stub Pressurization
This unit has an air pressure cutoff valve, air stem Schradervalve, andpressure relief valve.The air pressure cutoff
valve is used to shut off the inlet air supply that is pumped from the main feeder cable through the 30-foot (9.144
M) stub into the HRE-506 enclosure.
•To shut off the inlet air supply, turn the air-cutoff valve clockwise 1 full turn.
•To turn on the inlet air supply, turn the air-cutoff valve counterclockwise 1 full turn.
To avoid pressure buildup, the pressure relief valve is set to release air at a maximum
pressure of 15 PSI. Due to manufacturing tolerances of the springs, this maximum
pressure has a tolerance of ± 3 PSI. This pressure and tolerance is well within the safety
concerns that may apply to the housing, personnel, or cable.
The pressure relief valve is not intended for controlling the air pressure that is being
applied to the housing cable.
