OVERVIEW
The PairGain®PG-Flex®FRE-860, FRE-865, FRE-867, and FRE-868 Remote Terminal (RT) Enclosures
(see Figure 1) conveniently mount RT line units (LU) and channel units (CU). The RT Enclosures provide
termination points for subscriber circuits, HDSL, auxiliary power, and metallic bypass pairs.
The units described by this document get power from the HDSL lines connected to the COT Shelf. For each
doubler installed between the COT Shelf and RT Enclosure, two additional power pairs are required from the COT
Shelf to the RT Enclosure.

INSTALLATION AND TURN-UP
The installation of an RT Enclosure involves the following procedures:
•mounting the RT Enclosure
•wiring the RT Enclosure
•turn-up and testing
•closing the housing
REQUIRED TOOLS AND TEST EQUIPMENT
•216 Tool (can wrench)
•flat-head screwdriver
•insulated-handled needlenose pliers
Be careful when working with telephone circuits. Dangerous voltages can be present. It is
unsafe to install telephone wiring during a lightning storm.
All wiring external to the product should follow the local wiring codes.
Always treat the HDSL pairs as if they were live with high voltage present. Use caution when
installing HDSL pairs that are already connected to a COLU, because dangerous voltages are
present on the HDSL pairs.
The COLU, unless previously disabled by means of Craft provisioning, periodically attempts to
power up the RT Enclosure by applying +/-130 Vdc to the HDSL pairs.

INSTALLING THE FRE-860 RT ENCLOSURE
The FRE-860 RT Enclosure has external mounting flanges with tapped holes for #10-machine screws for pedestal
mounting.
1Remove horizontal crossbars from the UP10900 pedestal prior to mounting the FRE-860.
2Attach the RT Enclosure to the pedestal frame, using the mounting flanges (see Figure 2). Use the mounting
hardware provided with the RT Enclosure. Follow local practices to ensure a secure mounting.
Figure 2. FRE-860 RT Enclosure and Termination Panel
3Termination points for Subscriber and HDSL wiring are on the back of the unit as shown in Figure 2 and
detailed in Table 2.
4Install 5-pin protector plugs for all connected pairs.

INSTALLING THE FRE-865 AND FRE-867 RT ENCLOSURES
The FRE-865 and FRE-867 RT Enclosures have external mounting tabs with clearance holes for 3/8-inch bolts
(see Figure 3).
1When mounting to a pole using the Pole Mounting Kit (150-2397-0x), ensure the kit and FRE-86x are fully
installed before connecting the cables. The customer must provide the appropriate mounting hardware.
Follow local practices to ensure a secure mounting. The FRE-867 has lifting tabs to facilitate the mounting
of the enclosure.

2Connect the HDSL cable stub as listed in Table 3. The FRE-865 contains only one system (designated as
System 1), the FRE-867 has two systems, System 1 and System 2.
