TAS 100 Series

Telephone Network Emulators

TAS 100 is the World’s Most Popular Family of Modem & Fax Test Instruments

For years, TAS 100 Series Telephone Network Emulators have been the choice of leading data communications equipment manufacturers and evaluators worldwide. TAS 100 now gives you all of the tools necessary to test the latest and most complex modem and fax modulation schemes. TAS 100 assures high product quality and eliminates costly and embarrassing field failures by providing a comprehensive set of testing capabilities. The investment in a TAS 100 Series Telephone Network Emulator can return many times its cost by eliminating product repairs and lost sales due to poor product quality.

The latest member of the TAS 100 Series family, the TAS 192 thoroughly tests all types of modems. TAS 192 meets and exceeds the requirements of the latest EIA/TIA industry testing standards, including TSB 37A. Enhanced frequency response characteristics provide a more accurate test bench for V.34 and V.34+ modems. TAS 192 also emulates conditions typically associated with local network connections, including short transmission delay and low trunk loss. Modem performance in one of today’s most common applications, Internet access over local telephone lines, can now be accurately evaluated. TAS 192 also contains a wide range of other impairments to fully exercise modem performance in a variety of real-world conditions.

TAS 100 Provides a Thorough, Accurate Test for any Device that Communicates over Voice-Bandwidth Telephone Networks

All TAS 100 Series models emulate a complete, end-to-end telephone connection and can be configured to represent 2-wire dial, 2-wire private, and 4-wire private lines. The units can also be configured as 4-wire at one station and 2-wire at the other station to facilitate testing cellular modems and remote access servers. In addition, the TAS 192 can be configured with a new line mode to allow two units to be cascaded together to simulate the effects of digital loop carrier (DLC) systems and private branch exchange (PBX) environments on modem performance. TAS 100 also includes programmable control of network configuration, central office (exchange) configuration, analog transmission impairments, digital facility impairments such as PCM and robbed bit signalling, and delay and echo levels.

TAS 100 provides the mix of critical features required for thorough evaluation in a compact, easy-to-use package. Designers can drama-tically reduce development testing time and costs. Manufacturers can detect and stop defective products before they reach the field. Product evaluators can select between data communications products based on real-life performance, not just the specification sheet.

In short, TAS 100 helps you to insure the quality of your modem, fax, or other data communications products.

Every TAS 100 Series Telephone Network Emulator lets you quickly and easily evaluate communications equipment performance with respect to:

■

Central office conditions such as loop current, ring voltage, call progress tones, etc.

■

Transmission impairments such as attenuation, gain distortion, group delay distortion, PCM distortion, robbed-bit signalling, and much more

TAS 100 Series

Telephone Network Emulators

Pre-defined network conditions for many countries can be recalled at the touch of a button!

TAS 100 Puts the World’s Telephone Networks at Your Fingertips

Pre-defined network conditions for many countries can be recalled at the touch of a button! TAS 100

also includes pre-defined transmission impairments conditions according to published Electronic Industries Association (EIA) specifications. Non-volatile storage is provided for user-defined test conditions.

TAS 100 Complies With U.S. and International Standards for Modem and Fax Testing

The TAS 100 Series meets or exceeds impairment generation specifications put forth by EIA/TIA, ITU (CCITT), Nippon Telephone and Telegraph (NTT), AT&T, Bell System, RITT (China), and U.S. Department of Defense. Built-in ROM files include setups for standard test conditions to assure compliance with existing and emerging test standards.

No Other Solution Packs So Much Testing Power Into A Single, Compact Enclosure

TAS 100 Series Telephone Network Emulators give you complete, bi-directional impairments emulation (models 182 and 192) and fully automatic, dual central office emulation, all in one compact package. Unidirectional impairments models (151) are upgradable to full impairments without adding additional boxes.

TAS 100 Is Easy To Set Up and Easy To Use

All TAS 100 operations are accessible via easy to use front panel menus. TAS 100 also provides a straightforward, logical set of remote commands to facilitate remote control via RS-232 or GPIB. If you’re designing your own automatic test software, you’ll find that programming the TAS 100 is a breeze.

TAS 100 Employs Advanced Digital Signal Processing Technology Throughout for Unsurpassed Accuracy, Repeatability, and Reliability

The TAS 100 Series provides precise, all-digital emulation of transmission impairments and call progress tones for precisely repeatable test results. Digital processing yields extremely low background noise, so you get accurate test results even at the lowest signal levels. Digital processing also yields high reliability, because the overall component count is kept to a minimum.

All-digital impairments mean rock-solid compatibility among TAS 100 family members. TAS 100 impairments are compatible with IEEE 743-1984 specifications to facilitate easy verification of emulator performance using standard measuring equipment.

Built-In Diagnostic Routines Insure the Integrity of Your Test Results

Built-in diagnostics check the performance of all TAS 100 subsystems. TAS 100 executes a complete set of self-diagnostics auto-matically upon power-up, and upon user command.
