<p>A system and method of communicating voice and data via a local packet network (LPN) (60) to and from a customer site (7). A remote digital terminal (RDT) (100) is provided at a customer site to interface a plurality of phone devices (10) and/or data devices (computer or LAN computers) (12) with the LPN via a local loop link, such as a Digital Subscriber Line or a wireless local loop (24). A host digital terminal (HDT) (200) is provided at a control site within or connected to the LPN that coordinates the communication of voice calls between the RDT and a PSTN switch (32) via the LPN and that coordinates the communication of data between the RDT and a data network within or without the LPN. Multiple telephone calls with the customer site can be supported by the RDT over a single local loop link connected to the LPN.</p> |
