Model 3500 Caller ID Telephone R&D / Production Tester

@

Product Overview:
The Rochelle Model 3500 Caller ID/Telephone Production Tester is a stand-alone instrument for full Central Office simulation of telephony and type 1 & 2 caller ID signals.

The Model 3500 has specific application for automated production testing of telephony devices with Caller ID, Call Waiting, and ADSI (Types 1, 2 and 3).

The Rochelle 3500 ships with user-friendly software that allows the user to set signal parameters such as level, frequency and duration for CAS, DTMF, and single-frequency tones. The product includes a built-in loop simulator, adjustable line current, and slow-speed modems for advanced telephony testing.

The Model 3500 has an RS-232 serial port for control from automated test programs written in languages such as C/C++, Visual Basic or LabVIEW.

The Rochelle 3500 is compatible with all major US and international Caller ID standards.


Model 3500 Options:
DOS Menu software with 8 Mbyte DiskOnChip memory upgrade:
This option provides user-friendly Caller ID menu software with choices for 12 different countries and seven different test options for each country selection. An additional 8 Mbyte plug-in memory chip is provided for the menu software.

DOS Menu software with 24 Mbyte DiskOnChip memory upgrade: This option provides user-friendly Caller ID menu software with choices for 12 different countries and seven different test options for each country selection. An additional 24 Mbyte plug-in memory chip is provided for the menu software and for storage of additional scripts.

DSP/104 Module: This option is a full-function DSP card that plugs into the 3500 PC/104 expansion bus with software that gives the 3500 advanced measurement capability, including full DTMF digit analysis of signals from a device under test.

Remote Control Software (Serial): This option allows the 3500 to be controlled remotely from a host computer over the serial port. Serial cable included.
GPIB/104 Module: This option is a full-function GBIP card that plugs into the 3500 PC/104 expansion bus with software that allows the 3500 to communicate over a GPIB connector with a host computer. GPIB cable included.

Model 3500-DEV Caller ID/Telephone Production Tester (Developer's Unit)
The 3500 developer's unit is ideal for use by developers who are designing custom tests on the 3500. The 3500-DEV combines all of the features of the 3500

Production Tester with the following options:

DOS Menu software with 24 Mbyte DiskOnChip memory upgrade

DSP/104 Module

Remote Control Software (Serial)

The cost of the 3500-DEV is less than the cost of the 3500 with the three options purchased separately.

(duration, frequency, amplitude, and twist )

Allows the user to vary Caller ID and telephony signal parameters for full R&D  and production testing of both Caller ID and advanced telephony functions.

Provides basic telephony simulation with support for most US and international Caller ID variations.

Selectable loop lengths Allows the user to insert an internal simulated line: either 3 km (9480 ft) or 6 km (19680 ft) of 24 AWG wire.
Simulation and tests for Bell 202 and ITU V.23 modems Allows testing of telemetry and Point of Service (POS) devices and peripherals.
Simulation and tests for V.26bis, V27ter, and V.29 fax modems Allows the user to send and receive faxes at programmable FAX signal levels.
Record and play audio files Allows the user to record and play m-LAW, A-LAW, PCM, ADPCM, and .wav files.
Programmable audio input and output attenuation (range from -24dB to +24dB) Allows the user to set the input and output signals level over a 48 dB dynamic range.
True RMS Measurements Allows accurate readings of audio levels and noise.
Simulation of Subscriber Pulse Metering (SPM) Allows simulation of 12 kHz and 16 kHz metering pulses used for European-type call charging in Europe
BT CLI wetting pulse measurement Verifies proper operation of CLI products used in the UK
Programmable noise generator Allows performance testing under noisy conditions.
Bit Error Rate Test (BERT) capability Allows data performance tests of low-speed modems.
Rochelle Script Language ™ (RSL) V version 3.0 or higher. Allows easy development of powerful test scripts for automated R&D and production testing without the use of complicated programming languages (C++, etc.). Scripts are compatible with the Model 3400 and Model 3410.
Ground (Earth) isolation Insures grounding problems do not compromise tests.
Warranty Limited one-year product warranty with full telephone and e-mail support, and software upgrades..
