The invention relates to a foreign exchange station (FXS) interface technology of IP voice communication equipment. In the prior art, well quantification and processing can not be carried out on a received signal by current self-made auxiliary test equipment; and an accurate determination can not be provided for a signal quality on a line; however, the above-mentioned problems can be solved according to the invention; and therefore, an external auxiliary testing apparatus, and a testing system thereof and a method thereof are provided in the invention. A technical scheme is characterized in that: an external auxiliary testing apparatus is composed of a foreign telephone interface, a ringing signal detection module, an on-off hook circuit, a signal detection module and an information interaction module. Beneficial effects of the invention are as follows: because the external auxiliary testing apparatus has a data processing capability, determination on a signal quality can be enhanced; and detection on product hardware can be carried out comprehensively and accurately; therefore, the apparatus is suitable for application to a testing system and a method thereof of an FXS interface of IP voice communication equipment.
Description
technical field [0001] The invention relates to an interface technology of a Foreign eXchange Station (FXS for short) of an IP voice communication device, in particular to a testing system and method for an FXS interface of an IP voice communication device. Background technique [0002] As a voice interface, FXS realizes the connection function between the external exchange system and the user's telephone set. It is widely used in voice communication. At present, the low cost and the improvement of transmission bandwidth make VOIP (Voice Over Internet Protocol, IP voice) The business has a broad market prospect, and the market demand is constantly increasing. As a result, the inspection efficiency and cost of batch voice equipment in industrial production have become urgent problems for many manufacturers to solve. [0003] The inspection of VOIP equipment focuses on the inspection of its FXS voice interface. For the inspection of this interface, the current common test meth...
