PPLICATIONS

The primary application of the HRE-504 remote enclosure is to house HiGain doubler units in an HDSL/T1 
transmission system. The HRE-504 is an outdoor enclosure with four single-width mechanical slots. It has a single 
gel-filled stub (HRE-504 List 1 and List 1B) or air-filled stub (HRE-504 List 2).

The gel-filled 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 
pressure relief valve, as shown in 

Figure 1 on page 2

. 

The air-filled 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 have primary gas-tube surge protection on all cable pairs.

The HRE-504 can be used to house the following doubler and repeater units:

•

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

All doublers and repeaters share the same generic slot pair assignments as shown in 

Table 1 on page 16
