A network device that allows packet relay across a public switched telephone network. The network device has a converter operable to convert a packet data stream to a public switched telephone network data stream. The converter may be a voice codec or a modem, as examples. The network device also includes a controller that can send signals in the public switched telephone network data stream identifying the network device as a packet device, receive signals indicating at least one other network devices are participating in a public switched transmission session with the network device, and then send the packet data stream across the public switched transmission network directly to the at least one other network device.

Packet telephony across the public switched telephone network

Apparatus and method for enabling bilateral transmission of digital data between a local area network and telephone company networks employing both analog and digital telephone lines. A modem modulates signals responsive to signals from a local area network representing an outgoing call to form digital telephone signals suitable for transmission by a telephone line and suitable for demodulation by receiving analog modems. A circuit switched time division multiplex bus transmits the digital telephone signals to the telephone line. The modem also demodulates incoming digital telephone signals to form digital network bus signals divided into packets. A packet bus transmits the digital network bus signals to a network interface which processes the signals and transmits them to the local area network.
