56K modem line tester

9 May 2001 Test & Measurement

Tempo's TR 56K modem line tester (up to and including 56 Kbps) is designed to test, qualify, and certify the modem transmission capabilities of POTS facilities. Its unique testing capabilities include loop current, connect rate, actual throughput and bit error rate testing (BERT). The 56K system consists of a central office rack-mounted unit and a portable field unit.

The CO unit plugs into a universal equipment bay, where it is powered by CO battery. Once the CO unit has been installed and assigned an ISDN BRI line, it functions as a dial-up circuit.

The TR 56K modem line tester offers a thorough and versatile system of testing. This allows telcos to improve the quality of their customer service. The manufacturer says that advantages to telcos are a reduction in repeat reports, improved installation reliability, and increased technician productivity.

Key features are: loop current; connect rate; actual throughput; BERT; automatically connects at highest rate; limited connection at selected rates; three attenuation levels: 0, -3 and -6 dB; stores test results; print/PC upload capabilities; dimensions: 109 x 57 x 206 mm; weight: 980 g; loop current 0 to 99 mA; 9600, 14 400, 19 200, 28 800, 33 600, 56 000.
