Description
The FRE-765 can operate in an outside plant environment. It can operate in a temperature
range of -40°F to +150°F (-40°C to +65°C) and a humidity range of 5% to 95% (non-
condensing).
The FRE-765 has external mounting flanges with a clearance hole for a 3/8-inch bolt for
pole or wall mounting. The customer must provide the appropriate mounting hardware.
When mounting to a pole using the Pole Mounting Kit (PN 150-1397-00), ensure that the
pole mounting bracket and FRE-765 are fully installed before installing cabling.
The FRE-765 gets power from the HDSL lines connected to the COT shelf in the
Central Office (CO). When a doubler is installed between the PG-Flex COT Shelf and RT
enclosure, two additional power pairs are required from the COT shelf and RT enclosure.
Two HDSL pairs are terminated in the FRE-765.
Provides three 25-pair Amphenol connectors (male) for subscriber line terminations.
Provides AMP Quiet Front insulation displacement connections for subscriber terminations.
The metallic bypass pair for subscriber line testing is terminated in the FRE-765. Do not
connect the bypass pairs between PG-Flex systems or to other DLC systems.
When using a doubler, add two AMP Quiet Front terminals to the FRE-765 to terminate
the auxiliary power pairs from the COT. Order the Quiet Front kit (PN 150-1399-25) which
contains two Quiet Front terminations, four jumpers, and a tool for inserting the jumpers
into the insulation displacement barrels.
Knockouts are located on the bottom of the FRE-765 and accept ¾-, 1-, 1½-, and 2-inch
fittings. Install grommet (provided with FRE-765), conduit, or cable strain relief fittings
prior to wiring the FRE-765.
Install 5-pin protectors (short housing) for each working subscriber circuit in the FRE-765
List 5A. These may be carbon, gas tube, or solid state protectors, depending on local
practice.
