Line tester qualifies transmission capabilities

9 May 2001 Test & Measurement

The TR 1096 modem line tester (up to and including 33,6 Kbps) tests, qualifies and certifies the modem transmission capabilities of POTS facilities. Its unique testing capabilities include loop current, connect rate, actual throughput and BERT. The unit provides a clear readout of transmission speeds before and after conditioning. These readings can then be used to identify a course of action to improve modem line performance.

The TR 1096 consists of a central office (CO) plug-in card and a portable field unit. The CO unit plugs into the MFT bay, where it is powered by the CO battery. Once the CO unit has been installed and assigned a telephone number, it then functions as a dial-up circuit. The field unit is powered by using an AC adapter or rechargeable battery pack. It contains the user interface, which controls all tests and functions. The field unit dials up the CO unit, initiates a carrier connection, and begins the testing sequence.

Main features are: actual throughput; BERT; originating and receiving call test; three attenuation levels: 0, -3 and -6 dB; auto dialler (up to 20 digits); disables call waiting function; stores test results; print/PC upload capabilities; field unit-to-field unit capabilities; optional single-ended testing (no callback from CO unit).

The unit measures 109 x 57 x 206 mm and weighs 980 g.
