Apparatus and method for broadband data communication

摘要

A device and method are disclosed for providing a phone LAN routing LAN traffic internally within Customer Premise Equipment (CPE) and for routing analog and digital traffic from a Public Switched Telephone Network (PSTN) to the CPE. A phone hub routes LAN traffic and incoming voice and ADSL to network elements having a network interface controller (NIC). Analog voice signals are transparently coupled through the phone hub. Inbound ADSL data is transported using the phone hub at LAN frequency to a NIC. Outbound ADSL data transported to the phone hub at the second frequency is frequency shifted by the phone hub back to the first frequency for transport over the PSTN. Broadband 10BASE-T Ethernet frequencies are accommodated using customer premise wiring.
