Microtronix Systems Ltd. is now offering a Customer Premises Equipment (CPE) Load Simulator product designed to the requirements of ANSI/TIA-470-C.

What is CPE Load Simulator?

A CPE Load Simulator models the AC and DC characteristics of a telephone. It is used to simulate a second telephone on the line during testing.

When is the CPE Load Simulator Required?

The CPE simulator is a stand-alone product to be used by test engineers, type approval facilities and laboratories when testing to ANSI/TIA-470-C. The standard has limits for Send and Receive Distortion, and specifies a maximum permitted change in loudness ratings when the CPE simulator is connected to the line.

Advantages of the Microtronix CPE Load Simulator

The Microtronix CPE Load Simulator meets and exceeds the requirements of ANSI/TIA-470.110-C. The Simulator’s performance is stable and repeatable over it’s range of operating conditions.

What is needed to use the CPE Load Simulator?

The CPE Load Simulator can be connected across the Tip and Ring output of any telephone test equipment. Binding posts are provided for connections.
