Compliance with all mandatory requirements in this AS/CA Standard is to be verified. This may be done by direct measurement,modeling and analysis, operation or inspection. Methods for demonstrating compliance of CE with the requirements clauses specified in this Standard are described in Clauses 6.2 to 6.3.Verification of compliance with the referenced standards may be confirmed by test reports to later versions of the referenced standards provided that all clauses of the referenced standards are shown to be met.
Alternative methods of demonstrating compliance to those described may be used if the risk of passing non-compliant CE is not increased because of increased measurement uncertainty.
In some CE the power level presented to line is dependent on excitation either internal or external to the equipment. This excitation may be determined from the appropriate product specification or with some CE this will require the connection of the associated CE to provide the stimulus.
Compliance with Clause 5 should be checked by performing this excitation then measuring the line signal as described by the appropriate tests.
Methods for external stimulus and excitation of the CE include the following:
(a) If the CE includes a voice frequency recording and reproducing element in which the signal recording is achieved either by the user or from signals injected into the recording element from the network, the supplier should provide documentation for the user describing how the power levels of signals transmitted to the network are controlled.
(b) If the signal level control is achieved by means of limiters, this should be checked by injecting voice frequency signals,where indicated in the documentation, at any level necessary to test that the limiters are restricting the signals to the network to the specified required limits.
(c) If the CE generates a modulated VF signal in response to an external stimulus initiated by the user, the supplier should provide documentation for the user describing the operating conditions and any associated signal generating devices.AS CA S043.3 pdf free download.
