The Telinc WAN 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 supplied 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.

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.
