ATM over an asymmetric digital subscriber line
This thesis investigates Asymmetric Digital Subscriber Line (ADSL) access networks and considers Asynchronous Transfer Mode (ATM) transport in the ADSL network. To analyse the ADSL access network, a simulation was developed using C++ and MATLAB. The thesis outlines the background and implementation …

Model-Based Identification of POTS Local Loops for DSL Connectivity Prediction
Accurate prediction of the Digital Subscriber Line (DSL) access rate - over an existing plain old telephone service (POTS) twisted pair local loop - is vital to DSL providers. We have approached the challenge as an identification problem of the local loop structure and its twisted pair parameters, …
