Abstract:
1. An integrated switch simultaneously processing voice signals and IP data, comprising: a plurality of line cards to convert voice signals of a plurality of subscribers to digital voice signals, outputs, add silent identifiers identifying silent periods of the voice signals of the subscribers to IP data of the subscribers, dispose the IP data comprising the silent identifiers in the silent periods of the digital voice signals of the subscribers, and output the digital voice signals and the IP data in the same channel; an internal switch which simultaneously switches the digital voice signals and the IP data comprising the silent identifiers in a time-division multiplexing scheme; and a plurality of input/output trunks which delete the silent identifiers from the IP data comprising the silent identifiers among output data of the internal switch and transmit the IP data to an external IP data trunk and the digital voice signals among output of the internal switch to an external voice phone trunk so that the silent identifiers can be used to identify packets containing the IP data transmitted in silent periods.
