PRODUCT OVERVIEW
Description and Features
The PairGain ® PG-Flex © FRE-765 List 4x Remote Terminal (RT) Enclosures (see Figure 1 through Figure 7 )
provide convenient mounting of one RT Line Unit and up to three Channel Units, supporting up to 24 channels.
The enclosures provide termination points for subscriber circuits, power, and metallic bypass pair. Terminations,
with internal gas tube protectors, are provided on the backplane for High bit-rate Digital Subscriber Line (HDSL)
and Bypass connections. Terminations may be added for auxiliary power pairs when PG-Flex is used with a
PG-Flex doubler. The enclosure can be pole or wall mounted and is environmentally sealed for outside plant
installations. Listed below are the FRE-765 enclosures described in this practice:
