ABSTRACT:
Systems and methods are provided for automatically configuring cross-connects in a switch. One exemplary embodiment is a digital subscriber line access multiplexer for automatically configuring a plurality of cross-connects comprising: obtaining a default logical VPI/VCI address associated with the plurality of data communications channels; defining a first plurality of unique logical VPI/VCI addresses based on a predefined set of rules for incrementing logical VPI/VCI addresses, each of the first plurality of unique logical VPI/VCI addresses associated with one of the plurality of digital subscriber line communications channels; determining a second plurality of unique logical VPI/VCI addresses based on the default logical VPI/VCI address and the predefined set of rules; and creating signal connectivity between the plurality of data communications channels and the plurality of digital subscriber line communications channels by linking the first and second unique logical VPI/VCI addresses.
