Product Overview
ADC Telecommunications HRE-204 L3A - a 4-slot remote enclosure built for the HiGain Wideband 3190 (WBS-3190) T1 distribution system. Houses up to four modular HiGain Remote Units (HRUs) or HiGain Line Units (HLUs) using 200-mechanics or 400-mechanics card formats. The integrated backplane carries DB15 connectors and RJ48C terminal blocks for T1 interface wiring. Cream powder-coated steel chassis with perforated top vent panel, three keyhole wall-mount slots on the rear panel, and side security latch points for secure remote terminal installation. Requires -48V DC at 0.5A for local powering of installed remote units.
Key Features

- Power input: -48V DC, 0.5A (local powering of HRUs/HLUs)
- Three keyhole wall-mount slots on rear panel; side security latch points
- Perforated top vent panel for passive thermal management
- UL listed E191387; QC and HI-POT OK stickers confirmed on chassis
- CLEI code T1M3G00; part number HRE-204 L3A stamped on chassis and confirmed on carton
- Compatible with ADC HiGain WBS-3190 T1 distribution system
Applications
- Network technician installing a remote T1 termination point at customer premises - mounts the enclosure, seats HRU or HLU cards into the four slots, and connects copper pairs via RJ48C to establish T1 voice and data service without deploying a full central office rack
- Field engineer restoring T1 backhaul at a remote branch location where the original HRE-204 enclosure failed - slots existing HiGain cards directly into the replacement chassis and returns the circuit to service same day
- Service provider maintenance technician extending an existing WBS-3190 distribution system to an additional remote site - uses the four-slot capacity to support multiple T1 spans from a single wall-mounted enclosure
- Telecom infrastructure manager sourcing a clean unused enclosure to hold as depot spare inventory for legacy copper-pair T1 and HDSL backhaul circuits still in active service
Frequently Asked Questions
Which HiGain remote or line units are compatible with the HRE-204 L3A?
The HRE-204 L3A accepts ADC HiGain 200-mechanics and 400-mechanics remote units (HRUs, H2TU-Rs, H4TU-Rs) and HiGain Line Units (HLUs). It is not compatible with PairGain legacy HDSL HRU-412 remotes - those use pin 1 for chassis ground, while the HRE-204 provides chassis ground on pin 27 only. Verify your existing units' pin assignments before ordering.
What power supply does the HRE-204 L3A require?
The enclosure requires -48V DC at 0.5A for local powering of installed remote or line units. A -48V DC power supply is not included.
What connector types are on this unit?
The rear panel carries four DB15 connectors and four RJ48C ports labeled CPE 1-4, confirmed by chassis label (catalog description: 4 SLOT REM ENCL,RJ48C,DB15) and photo evidence. The L3A variant uses RJ48C - if your network requires RJ48X for DSX-1 interface, the L3B or L3C variants apply instead.
How does the L3A differ from other HRE-204 list numbers?
The HRE-204 family includes multiple variants. The L3A uses RJ48C connectors. The L3B uses RJ48X connectors for DSX-1 interface; the L3C uses RJ48C. List 1A uses RJ48C DS1 connectors; List 2A uses RJ48X. Confirm your required connector type and grounding scheme before selecting a variant.
Are cards, power supply, or documentation included?
No cards, power supply, or documentation are included. The enclosure ships as photographed - chassis only, in original manufacturer's packaging.
T1 infrastructure runs quietly in the background until something breaks - and when it does, the search for an exact-match enclosure that has never been field-deployed becomes very focused, very fast. This one has been waiting in its box.
