Application And Optimal Design Of Digit Voice Processor In The Next Generation Network

The Next Generation Network's development focus on the multiple service architecture from previously separated audio and digital service architecture. The rising of e-business, network multimedia and VoIP services are now pushing the Internet to a new development era. In this phrase, being the competition focus between equipment provider and service provider, the variety, content and quality of service will play a more important role.The Next Generation Network is not only the telecom network,and it is not the IP network and the prolongation of them,neither is the single nod technology and the network technology,it is the transform of the whole network architecture and a integrated solution.The birth and development of the next generateon network is not a revolution,it is a diversification step by step.that is,it is a smooth-transition base on the advantages of the current network.the design idea of the next generateon network system architecture uses the diversification mode to make it transit smoothly.VoIP acts as the role from PSTN telephone to IP phone in the next generateon network.In the last years,the cheap fee of VoIP had made it develop very quickly.At the same time,the most important part,digit voice processor also made a quick progresss,which can support more and more kind of codec and its performance more and more strong.The VoIP gateway that we R&D can support 4 E1 interfaces,it used Mindspeed M82610 as the kernel part,which can support a lot of codec types and multiple data operation,such fax,modem and so on.The whole solution uses double CPU,which has flexible operation.The test testified all kind of targets can meet the requirements,and it is compatible with other digit voice processor in the voice and data operation.This voice gateway had applied for the patent protection.I will introduce the feature list and the core component of Mindspeed digit voice processor,M82610 in this document firstly,and then I will show the internal theory of this digit voice processor.after that,I will introduce the system design of this gateway in detail and open out the detail information for the driver.base on this design,I will show some voice enhancement ways.At last,I put forward some improvement idea aim at the development situation of the next generateon network.
