A. PRODUCT OVERVIEW
1. Description and Features
1.1 The PairGain® PG-Flex™ FCS-718 List 4 19-inch Central Office Terminal (COT) Shelf
(Figure 1) supports:

one Alarm Unit or PGTC Interface Unit that is common to both systems

two PG-Flex subscriber carrier systems where each system comprises one Line Unit and from
one to six Channel Units (for a shelf maximum of two Line Units and 12 Channel Units)
Additionally, the shelf provides termination points for alarms, power, metallic bypass pairs, auxiliary
power pairs when using a doubler, and subscriber circuits (located on the backplane at the rear of the
shelf). The List 4 COT Shelf provides cable adapters with 25-pair Amphenol connector terminations
for the subscriber circuits.

Use the List 4 FCS-718 COT 19-inch Shelf only with a List 4x (or higher) FRE-765
Remote Terminal Enclosure.
1.2 Features of the PG-Flex FCS-718 COT Shelf are:

universal mounting brackets for installing in a 19- or 23-inch equipment bay

wire-wrap connections for HDSL, alarm, metallic bypass pairs, and auxiliary power pairs (when
using a doubler)

screw terminal connections for frame ground and dual Central Office (CO) battery

DB-25 connector for Network Management Analysis (NMA) communications

25-pair Amphenol cable adapters for connection to CO switch subscriber lines

B. FUNCTIONAL DESCRIPTION
3. Operational Capabilities
3.1 Each system (one Line Unit and from one to four Channel Units) shown in Figure 1 can support up to
24 or 32 subscriber channels. Each Channel Unit can provide four (4) or eight (8) channels,
depending on the service offered. Services offered are:

Plain Old Telephone Service (POTS)

Integrated Services Digital Network (ISDN)
A label on the FCS-718 shelf indicates numbering for the Line and Channel
Units. When the Line Units are a List 1 or 2, black numbers indicate sequential
Channel Unit numbering 1 through 12. When the Line Units are List 3 or higher,
blue numbers indicate Channel Unit numbering 1 through 6 for each system.
3.2 Tables 1 and 2 show how to utilize channels, dependent on the Channel Unit (4 or 8 channels) and
the type of subscriber service (i.e., POTS, ISDN) selected.
