Abstract (en)
[origin: WO8912368A1] A portable call generator for generating repetitive telephone traffic test signals for testing the performance of a telephone exchange interconnect circuit connecting a first test line number to at least one second test line number. The test apparatus comprises an ''A'' line interface (5) and a ''B'' line interface (8) for coupling first and second test numbers to a programmable processor (1) in which a plurality of test parameters can be selectively stored in an associated memory (2). The A line interface is activated by signals from the processor to seize the first test number, establish a connexion between the first and second test numbers, and perform selected tests on the interconnect circuit.
