ABSTRACT:
A digital subscriber loop access and multiplexing (DSLAM) circuit for use at a central office site is disclosed. The DSLAM circuit couples to a digital subscriber loop (DSL) and permits a downstream user to set up and configure an end-to-end connection with destination customer promise equipment (CPE) at a target data rate using any one or more of a regular switching telephone network, various kinds of wide area networks, or virtual permanent circuit links via digital cross-connects.
