Telinc WAN Tester III data network analyser

The Telinc WAN Tester III is a bit error rate tester in a compact, handheld package. It can test a wide variety of communications facilities and equipment including T-1, fractional T-1, E-1, fractional E-1, T-3 and E-3 modems, multiplexers, CSU/DSUs, T-1 CSUs, DTUs, NTUs and TIUs. It is supplied with user-changeable nickel metal hydride batteries and a built-in charger.

In the T-1 and E-1 modes, the Tester displays bit errors, transmit and receive frequency, test seconds, bit error rate and G.821 performance measurements. A variety of test patterns can be inserted in all or selected DSOs/Timeslots, continuous or non-contiguous, making the Tester suitable for fractional T-1 or E-1 testing. Because it contains two T-1/E-1 framers, it can measure bit and frame slips as well as monitor and listen to both the TX and RX DSOs and Timeslots simultaneously. It can also perform Drop/Insert (D/I) testing a single DSO or Timeslot without interfering with the remaining ones.

The WAN Tester III can test T-3 and E-3 networks and CSUs. It performs G.821 measurements and displays bit errors, bit error rate, frequency and more. With the dual T-3/E-3 TX and RX framers and codecs, it can monitor both sides of the line so it can listen to voice on a DSO or Timeslot on a channelised T-3/E-3.

In the async and sync test mode, the Tester generates test data in a choice of patterns and formats. The user can choose from 28 async and 75 sync test speeds. In the async mode, it displays characters received, character errors and errored seconds. In the sync mode, it displays bit errors, bit error rate, TX frequency, RX frequency, CTS delay, G.821 measurements and more.

The WAN Tester III can generate and store reports useful for line turnovers, troubleshooting in the lab or diagnosing a communication line issue. The WAN Tester III can be controlled from the front panel or from a local or remote terminal. It includes a 320 x 240 colour LCD that shows selected mode, test and operating parameters. Parameters are selected by scrolling through values stored in the tester.
