FX System Line Boards

Loop Start Line Board

Part Number: FXLST-16 (16-port Analog)

• These line boards support basic loop start lines from the local Telephone Company.

• Loop start lines are the most basic line application and, typically, the least expensive type of

line for a telephone system.

• Every loop start line board provides a tip and ring pair connected to line 1 as an emergency

power failure circuit.

• This power fail circuit is active during a commercial AC power failure if an external battery

assembly is not installed to provide battery back-up power to the system. Pair 25 (pin

numbers 50 and 25, clip terminals 49 and 50) on the line board connector jack provides the

power failure connection.

• Each line board makes one auxiliary equipment connection available for use. This

connection is at Pair 24 (pin numbers 49 and 24, clip terminals 47 and 48) and is associated

with line 2 of that line board.
