The HiGain Remote Enclosure HRE-206 List 1 and List 2 house up to six 200-mechanics HiGain remote units
(HRUs or H2TU-Rs), one protection switching controller card (PSC-606 List 1), and an optional power supply.
The remote enclosure is used as a 1+1 (redundant) or 1+N (revertive or non-revertive) protection enclosure when
the protection switching controller card is installed. The HRE-206 must meet the following system requirements
for the protection switching application to function: HXU-358 multiplexer (software version 1.04 or higher), an
HMU-319 List 7A or 7C (version 3.06 or higher), an HRU-402 or H2TU-R-402 (List 6) remote unit, and a
PSC-606 protection switching controller card.
The HRE-206 List 1 has RJ48C DS1 connectors, and the HRE-206 List 2 has RJ48X connectors. When the
PSC-606 card is not installed, the HRE functions as a standard 6-slot enclosure.
The remote enclosure supports the 1+1 protection function when an HRU-402 or H2TU-R-402
(List 6) is installed in slots 5 and 6. Slot 6 is the protection slot, and slot 5 provides protection
to slot 6 in the event of a failure.
The enclosure supports a 1+N protection function when an HRU-402 or H2TU-R-402 (List 6) is
installed in protection slot 6. Any or all of the remaining slots may be occupied by any remote
unit.
