 The MT4000 Tester is a sophisticated bit error
rate tester in a compact, hand held package. It can test a wide variety
of communications facilities and equipment including T-1, fractional
T-1, E-1, fractional E-1, modems, multiplexers, CSU/DSUs, T-1 ESF
CSUs, DU, NTUs and TIUs. It is sup-plied complete with V.35, RS232,
RS422/RS530, X.21, DS1 (T-1, 1.544 Mbps) and G.703 (E-1, 2.048 Mbps)
interfaces. The Tester is supplied with a wall-mounted AC transformer.
A battery option is also available for complete portable operation.
With the option, a nickel metal hydride battery and a recharger are
built into the Tester.
o Speeds from 50bps – 8,192Mbps Interface
o E1 and T1, Fractional T1 and E1
o V35, V24, RS422/ RS530, X21 Interfaces
o Displays G821 measurements
o Front panel or VT100 console control
o Multiple test patterns
o 16 LED indicators plus 2 line LCD display
o Both Battery and/or mains power
T-1 and E-1 Testing
The user can choose from
four operating modes: T-1, E-1, asynchronous and synchronous. A
variety of test patterns can be inserted in all or selected time
slots/DS0s, continuous or non-contiguous, making the Tester ideal
for fractional T-1 and E-1 testing. In the T-1 and E-1 modes, the
WAN Tester counts and displays bit errors, transmit and receive
frequency, test seconds, bit error rate, and G.821 performance
measurements (errored seconds, severely errored seconds, degraded
minutes and available and unavailable times). In the T-1 mode it
also displays receive level.
Asynchronous and Synchronous
Testing
In addition to T-1 and E-1, the WAN Tester provides asynchronous and synchronous
test modes. It generates test data in a choice of patterns and formats. The user
can choose from a selection of twenty-eight asynchronous and seventy-five synchronous
test speeds. The Tester counts and displays bit errors, bit error rate, and total
test seconds. In the asynchronous mode, it also counts and displays characters
received, character errors and errored seconds. In the synchronous mode, it also
displays transmit frequency, receive frequency, clear to send delay and G.821
performance measurements.
Easy to use
The WAN Tester can be controlled from the front panel or from a local or remote
VT100 terminal. It includes a two-line LCD display and sixteen indicator lights
that show selected mode, test and operating parameters. Parameters are selected
by scrolling through values stored in the Tester. All operations can be performed
using only ten keys.
