Abstract: Starting with traditional telecom network, it's analyzed that telecom carriers, service suppliers, enterprises and end users are facing problems in the field of traditional voice communication and vigorously growing data communication, and a new technology as TDMoIP is educed. after a brief introduction of such relative technologies as IP、UDP、TDM、AAL1/2、MPLS and Ethernet, the working principles, signaling reliability, time synchronization and QoS's guarantee of TDMoIP are discussed in detail. in chapter four, a comparison is being made regarding TDMoIP,VoIPand VoDSL and their developing directions analyzed respectively.In the later part of the paper, some relative solutions are put forward as well as some qualitative analysis. Finally, TDMoIP technology and the  improvement and enhancement needed in its development are brought forward according to my own professional knowledge.

i wonder how to improve this vision

Abstract: Based on the traditional telecom situation, this article provides analysis of the problems confronted the telecom carriers, service suppliers, operators, and end-users in the fields of traditional voice communications and flourishing digital communications, thus elicits the emerging technology of TDMoIP. Following a brief introduction to relative technologies such as IP, UDP、TDM、AAL1/2、MPLS and Ethernet, is a detailed analysis of the principles of TDMoIP, signaling reliability, time synchronization and QoS's guarantee of TDMoIP. In section four, there is a brief comparison on TDMoIP, VoIP and VoDSL, and a analysis on their prospects respectively. Finally, in addition to some pertinent solutions and then some qualitative analysis provided, rooms for modifying and strengthening as to the TDMoIP technology and the course according to what I’ve learned.
