The tendency of the technology that is aggregated voice and data circuit is VoP, especially VoIP. But if we try VoP, we have to throw away well structured and well known TDM resources. In this case CLEC and ILEC will encounter lots of troubles about standardization of progress of network evolution, heavy cost of network construction and so on. Therefore in this paper, I suggest designing VoDSL terminal and its operation environment (such as DSLAM) based on TDM. This designed VoDSL terminal can be installed with the DSLAM between PSTN and ISP without any additional facilities. This is more convenient low cost, operation and easier to construct than VoP.
