A
PPLICATIONS
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
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
•
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
