Abstract

A method and apparatus for testing a conference server. A plurality of test tone signals are generated. In one embodiment each test tone signal comprises the sum of at least two distinct frequency signals. Each test tone signal is employed to simulate a participant and the test tone signals are applied to a plurality of inputs of the conference server. At least some of the test tone signals are combined by the conference server to produce a corresponding plurality of test output signals. The test output signals are analyzed to identify whether the proper test tone signals are present within the respective test output signals. The generation of test tone signals and the analysis of the conference server outputs may be automated to facilitate rapid testing of conference server functionality. An indication of the test results are generated.

Claims15

Dependent claims

A method for testing a conference server for use in a telephone network, said conference server having a plurality full duplex channels, each channel including an input to the conference server and an output from the server, said method comprising the steps of:

in a first generating step, generating a plurality of unique test tone signals;
applying a different one of said plurality of test tone signals to each one of said plurality of conference server inputs;
selectively combining at least some of said test tone signals within said conference server to generate a plurality of test output signals corresponding in number to said conference server inputs and coupling said test output signals to selected ones of said conference server outputs;
analyzing said conference server outputs to identify which of said plurality of test tone signals are present within said conference server outputs;
and
providing an error indication in the event at least one of said test tone signals detected within said conference server outputs does not correspond to a corresponding expected test tone signal.
