Model 501 Test System

The Model 501 Telephone Test System is a complete testing solution for measuring the electrical and acoustical properties of a telephone in Production Line and Quality Assurance environments. Rugged in design to meet the needs of high volume telephone production, the Model 501 is flexible and accurate for the ever-increasing demands of specification testing. Simple and easy to use interface to increase productivity, and fully programmable to allow every telephone to be tested in seconds!

Test System Features

• Up to 48 different Test Programs containing limits and testing sequences can be stored in non-volatile RAM
• Easily integrated into an automation environment to control solenoids and remote programmable controller allow complete testing of a telephone without human intervention.

Country Kit Applications
• The Model 501 test system can use the complete catalogue of Microtronix Country Kit applications which provide standards compliant testing for all major telephone markets worldwide. Each Country Kit provides hardware and software to allow the test system to test to a country specifications. See our list of Country Kit Applications.
• Microtronix can provide create testing packages for additional countries not listed above or create test software to your specification.

TESTS
The following are typical tests performed by the Model 501 Telephone Test System. Other tests are available which are customized to their countries requirements. Contact Microtronix or your Local representative for details.
Acoustic Transmisson Tests:
Frequency Response measurements for Transmit, Receive and Sidetone. Absolute, Best Fit or relative limits are provided depending on the country specification. Loudness ratings selectable for ITU-T, OLR, OREM-A or OREM-B. Tracking Bandpass filters are used to reduce the effects of factory noise on the results.
Transmit and Receive distortion are also provided at pre-determined frequencies.

Return Loss:
Compares phone to selectable reference impedance in the Modules Unit. Echo return loss computed per ITU-T G.122
DTMF Dial Test:
Measures voltage, frequency, duration, twist, total power of the high and low group tones simultaneously. Memory locations and re-dial can also be tested for the correct sequence of digits as specified in the test program. DTMF tone bursts as low as 40mS can be detected and measured by the test system. Acoustical verification of transmitter muting during dialling and comfort or confirmation tone can be performed. DTMF distortion on Button 1, 5, 9 and O are also available (option).
Pulse Dial Test:
Measures pulse speed, make/break ratio, make/break resistance interdigital duration. These are important measurements to be performed especially when the phones are being used on a legacy network.
Ringer Tests:
Allows either mechanical and electronic ers to be tested for ringing capability at different voltages, frequencies and ring cycles. Amplitude, frequency and ring cycle is programmable by the users. Ringer capacitance and leakage resistance test are also implemented.
Caller ID Test for Type 1, Type 2 and Type 2.5:
Bellcore, CLIP SIN242 and ETSI Caller ID tests are provided with the test system. Name, Number, Acknowledgement Tone and Caller ID with Disposition provides the knowledge the products under test are disying the correct information. DTMF Caller ID capabilities can also be implemented in the test system.
