Acoustic Telecom Tester 213A

Our complete Acoustic Telecom Test System consists of the following instruments:

• Telecom Tester 213 with artificial line and acoustic module
• Artificial Head 214
• PC Test Software 115
• Test Feed Coils 215 (for test with artificial line)

and, optionally,

PC Test Software 115

For uncomplicated and fast programming and test with the 213.

Telephones can be tested for ringing, dial pulse/DTMF, and acoustic in 30 seconds.
All tests are carried out step by step by using only single key strokes.

For development and quality assurance of handsets, the frequency response of receiver, transmitter, and sidetone can be plotted on the screen.

Artificial Transmission Line 119

Simulate telecommunication cables.
Two different cables in the same box.

Used for testing of telephones, telephone exchanges and data transmission equipment.
It consists of RC networks.
Lengths selected by pushbutton switches 0.5km to 15.5km. Also can be remotely controlled from a PC.

Standard lines are available and special lines made to order.

Telephone Number Display 209

Identifies a caller's telephone number before the first ring by decoding DTMF information from the telephone exchange.
Prevents telephone abuse.
Memory stores the last 100 calls together with the date and time of the call.
Can also be used as a simple call logger for outgoing calls.
RS 232 output for printer or PC.

Dial Pulse & DTMF Tester 210

Tests dial pulses and DTMF.
Stores up to 80 digits and displays faults.

Measures dial speed, duty cycle, make and break times, inter-digit pause, flashing times, DTMF frequencies,
tone on and off times, and levels in mV or dBm.
8 different pass/fail test limits.

Optional:
- Centronics output for a PC or printer
- Fault output for LED or relay

Telecom Tester 213

Multi-function tester measuring dial pulse, DTMF, earth recall and Loudness Rating, EIA 470 and OREM A/B/CH standard. Generates feed supply and ringing, DTMF, 12/16kHz meter pulses and test tones.

Built-in artificial line 0 to 8km.
IEEE 488 bus interface.
RS 232 output

Artificial Head 214

The Artificial Head is intended for high speed production testing of the electro acoustic transmission characteristics of telephone handsets.

In conjunction with the Telecom Tester 213 the frequency response of the handset transmitter, receiver and sidetone can be measured in accordance with Loudness Rating, EIA 470, and OREM A.

The Artificial Head is very robust and meets the requirements for a fast and accurate production testing of telephone handsets.
It is also very useful for development and quality assurance.

The microphone with amplifier in the ear can be used for calibrating the artificial mouth when placed in the calibration jig or SFERT baffle.

Test Feed Coils 215

The two feed coils are intended for use in laboratories as a feeding circuit when testing telephones and other telecommunication equipment.

Feeding coils are especially applicable for type approval tests as they allow DC current and have a high impedance against AC.

The bench unit contains 2x5Henry (or 2x10Henry) coils constructed to maintain full inductance although a DC current of up to 200mA (125mA) is flowing through each coil.

The unit contains a polarity reversal switch and an inductive spike suppression circuit.

Necessary for test with artificial line in the 213.

Feed Voltage Adapter 218

See also: Dial Pulse & DTMF Tester 210

The 218 is powered via the mains and a telephone can be connected to its constant current output via a suitable plug.

Two different output impedances can be selected for testing dial pulse and DTMF systems. When a ringing signal or dial tone is required, a push button is pressed and one of the two signals will be generated on the line.

The 218 has a 15V DC output to feed the Dial Pulse and DTMF Tester 210, when they are used in a measuring set-up.

Telephone Number Analyzer 219

Used for documentation of the traffic.
Monitors 2 telephone lines detecting outgoing and incoming calls.

Call logging for dialled number, time of the call, length of the conversation. Caller ID in DTMF can be detected as well.

Optionally, meter pulses can be detected and cost of the call calculated.

Also optionally, time of the first telephone ring and number of rings can be printed out via the RS 232 output.

12/16kHz Payphone Tester 306

Tests payphones and telephone meter equipment.

The receiver measures frequency, level and length and number of received pulses and the last 5 measurements are stored.

Generates a pulse every second.

The level, frequency and length of tone can be set by the cursor buttons.

Test Telephone 540

A lineman's telephone for field use.
It is small and light, but solid and stands dust, humidity and to be dropped.
It has a large clip on the back and can be carried e.g. in a belt or pocket.

Replaces a normal telephone and measures the DC level on the line.

It detects meter pulses to a payphone or private meter as well as ISDN or PCM traffic.
Communicates over a leased pair of wires using the internal battery
