Handheld testing for basic and primary rate ISDN

26 January 2005 Test & Measurement

Trend's Aurora Duet is a solution to problem issues associated with the operation of ISDN. Available as a basic rate or combined basic and primary rate test instrument, it is capable of providing a complete range of test functions. It can simulate on the basic rate 'S/T' or 'U' reference points allowing a full combination of TE, NT and LT modes. This also includes EOC loopback commands and on the primary rate interface in TE or NT mode, either directly at the exchange or at the customer's premises.

Hotkey access is provided to instantly view G.703 and G.704 error counts and messages when in monitor or simulation test modes. Physical layer 1 testing and monitoring using LEDs and screen give indication of remote alarm, CRC error, sync alarm, signal detect, AIS, activation, info status and a number of other key indicators.

The Aurora Duet may be controlled remotely via a PSTN modem or ISDN TA. This allows realtime testing to take place or tests to be set running with dial-up and download of results.
