PPLICATIONS
HiGain provides a quick and cost-effective way of delivering T1 High Capacity Digital Service (HCDS) to
customers over metallic cable pairs. The HRE-204 houses units for a HiGain repeaterless T1 transmission system.
The HRE-204 List 1A and List 2A uses standard 200-mechanics and 400-mechanics slots
and can accommodate any plug with 200-mechanics or 400-mechanics, including the
HiGain HRU-402 (HDSL) and H2TU-R-402 (HDSL2) remote units, and the HLU-432 (HDSL)
line unit.
Since the HRE-204 supports chassis ground to pin 27, it is not compatible with PairGain
legacy HDSL HRU-412 remotes that only use pin 1 for chassis ground.
The HRE-204 provides a chassis ground connection to pin 27 only in every slot.
