Abstract
A system for the exchange of digital information packets includes an exchange with connectors to allow modular expandable units to connect to the exchange over transmission media. The modular expandable units send digital information packets from one to another over the exchange in response to requests for these digital information packets. The exchange allows for billing and other administrative functions.
