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
■
Satellite delay and echo
TAS 100 is the easy way to test modems,
fax machines, telephone sets, and 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.
