ABSTRACT:
This apparatus for testing an asymmetric digital subscriber line includes, arranged in a case, a low-frequency signal generator which generator is adapted to be connected to an input terminal block of an access multiplexer of a telephone exchange and which generator is adapted to inject into the latter a signal simulating the presence of a telephone line, an amplifier linked to a speaker and intended to be connected to an output terminal block of the said multiplexer and intended to retrieve and amplify the signal transmitted by the generator to an audible level, and a modem intended to be connected to the said output terminal block to test a modem of the access multiplexer by checking synchronization between these modems.
