RESUMO

This work presents new technologies for TDM emulation over packet networks, as an alternative to VoIP applications, saving network investments. After that, it proposes TDM pseudo-wires as an option to reduce digital video transmission costs, introducing a new kind of IPTV application. The work proposes new algorithms to improve solutions to TDM over IP main challenges: packet-sequence processing and clock-recovery at receiver. These algorithms are described and implemented using simulation at MatLab and Simulink, and tested using a simple Java-based application to deploy TDM over IP on a real network at LabCom/UnB. Moreover, it also presents experimental results from a commercial solution for TDMoIP technology, developed by RAD Data Communications, Inc. and used to deploy trunk E1 circuits for a Trópico-RA voice switch, in several conditions, analyzing pseudo-wire behavior and link quality as viewed by that switch. Finally, this work provides a comparison between that and proposed solution.
