Product Description

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.

E-1 and TE-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.
