A. PRODUCT OVERVIEW
1. Description and Features
1.1 The PairGain® PG-Flex
 FCS-719, List 2, 23-inch Central Office Terminal (COT) Shelf (Figure 1)
supports:

one alarm unit or PGTC Interface unit common to all systems

up to four PG-Flex subscriber carrier systems where each system comprises one Line Unit and
one to three Channel Units (for a shelf maximum of four 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 2 COT shelf provides wire-wrap terminations for the subscriber circuits.
Figure 1. FCS-719 COT Shelf (Card-side, Front View)
Use the List 2 FCS-719 COT 23-inch Shelf only with List 4x (or higher) FRE-765
Remote Terminal Enclosures.
1.2 Features of the PG-Flex FCS-719 COT Shelf are:

universal mounting brackets for installation into a 23-inch equipment bay

wire-wrap connections for HDSL, alarms, metallic bypass pairs, and auxiliary power pairs (when
using a doubler)


B. FUNCTIONAL DESCRIPTION
3. Operational Capabilities
3.1 Each system (one Line Unit and one to three Channel Units) can support up to 24 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-719 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 3 for each of the
four systems.
3.2 Tables 1 and 2 show how to utilize channels, dependent on the Channel Unit (four or eight channels)
and the type of subscriber service (POTS or ISDN) selected.
