摘要： A method for soft switch call control and a soft switch device therefore are provided. The soft switch device acquires an initial address message (IAM) at a calling side, analyzes information of the calling party and the called party based on the acquired initial address message (IAM), and informs the media gateways to create a context and to add TDM semi-permanent physical terminations of time slots corresponding to the calling party and the called party into the context when the calling party and the called party are controlled by the same media gateway. Thus, it can implement a local loop of TDM voice, reduce IP loop of RTP streams and efficiently reduces network resources such as steps for digital signal processing, echo elimination and etc.

摘要： A Residential Ethernet switching apparatus for performing time slot switching includes an input unit for receiving frames as input, and a parser for parsing the received frames into asynchronous Ethernet frames (AsyncE frames) and Residential Ethernet frames (ResE frames). An AsyncE switching processor performs a switching operation for an AsyncE frame parsed by the parser. A ResE switching processor performs, according to positions of time slots included in a ResE frame parsed, a virtual MAC (VMAC) processing for the ResE frame The ResE switching processor also performs a switching operation based on a result of the VMAC processing. A multiplexer multiplexes the AsyncE frame switched by the AsyncE switching processor, and the ResE frame switched by the ResE switching processor, for output.
