A. PRODUCT OVERVIEW
1. Description and Features
1.1 The PairGainPG-FlexFRE-765 List 5xRemoteTerminal (RT) Enclosures (Figures 1 and 2)
provide convenient mounting of one Line Unit and up to four Channel Units, supporting up to 32
channels. The enclosures also provide termination points for subscriber circuits, auxiliary power
pairs, and metallic bypass pair. AMP Quiet Front™ terminations, with internal gas tube protectors,
are provided on the backplane for HDSL and Bypass connections. Optionally, you can add AMP
Quiet Front terminations 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.
Use the List 5
x
RT Enclosures only with the FCS-718 List 2 (or higher) or the
FCS-719 List 2 (or higher) COT Shelves.

1.2 Features of the FRE-765 RT Enclosure List 5x include:
•pole or wall mounting
•line power from Central Office Terminal (COT)
•AMP Quiet Front terminations for HDSL inputs, metallic bypass pair, and subscriber
connections (List 5A only)
•AMP Quiet Front terminations can be added for auxiliary power pairs when PG-Flex is used
with a doubler
•5-pin protector strips and AMP Quiet Front terminations for subscriber connections
(List 5A only)
•¾-, 1-, 1½-, 2-inch cable entrance conduct knockouts with rubber grommet
•hinged cover over electronics inside the RT Enclosure
See Table 1 to identify which features are available with each RT Enclosure List 5xmodel.

B. FUNCTIONAL DESCRIPTION
3. Operational Capabilities
3.1 The FRE-765 List 5xRT Enclosure requires the following plug-in units:
•one RT Line Unit which is line powered via the HDSL pairs that connect the RT to the PG-Flex
COT installed in a COT Shelf.
•one Channel Unit, minimum, with a maximum installation of four Channel Units, supporting up
to 32 channels.
Section 363-765-105 June 2, 1997 Revision 01
Page 4 PairGain Engineering - Plant Series PG-Flex FRE-765
3.2 Table 2 shows how circuit assignments are configured in the FRE-765 with the following
deployment rules:
•For channel units providing four (4) circuits, Ckt 1 through Ckt 4 are used for Tip and Ring
terminations.
•For channel units providing eight (8) circuits, Ckt 1 through Ckt 8 are used for Tip and Ring
terminations.
•For a 32-channel system, you can provision a maximum of 32 circuits.
Each PG-Flex channel unit provides four (4) or eight (8) circuits. Table 3 shows how the channels
are assigned, dependent on the type of service provided, such as:
•Plain Old Telephone Service (POTS)
•Integrated Services Digital Network (ISDN)
•Digital Data System (DDS).
