Chapter 1: Overview
This manual describes the Telephone Line Simulator-4A which tests
telephones and other telecommunications devices.
The TLS-4A Telephone Line Simulator offers a convenient means for setting
up temporary “telephone lines” to demonstrate or test equipment where
actual central office lines are not easily available. The TLS-4A provides four
simulated lines, two “talk paths” or connections, and an audio interface port,
making it a versatile device for a variety of applications including:
•
Demonstrating or testing telecommunications devices such as
telephone sets, fax machines, and modems. Two simultaneous,
independent conversations can be set up over the four lines.
•
Playing prerecorded presentations over a line when the telephone
handset is lifted (for example, at trade show or museum displays)
•
As a teaching aid with the audio port configured to allow monitoring
and/or recording of a telephone conversation (for example, when
teaching children to use “9-1-1”)
• Testing telephone or key system installations
• Limited testing of loop start PBX installations
Static Protection
Use standard precautions in discharging electrostatic buildup before
operating this equipment or any other electrical equipment.
