A system and method for enabling a subscriber to receive incoming telephone calls on a telephone line and ring all of the telephones connected to a first conductor pair inside the subscriber's premises, wherein the first conductor pair would have normally been connected to the line. The telephones may be rung even when the subscriber is performing data communications with a remote data site on the telephone line. This obviates the necessity of the subscriber having to purchase a second telephone line for incoming calls while data communications are being performed, thus reducing access costs. The system and method shown advantageously employs a wiring device to reroute the telephone line from the first conductor pair connected to the phones to a second conductor pair normally not used. The system and method further employs a modem which receives telephone signals from the telephone line via the second conductor pair. The modem comprises a Central Office (CO) simulator circuit coupled to the first conductor pair which regenerates the telephone signals, such as a ringing voltage, to the telephones via the first conductor pair. When the modem is performing data communications with a remote data site, the remote data site also sends signals, such as data frames or IP packets, to the modem indicating that an incoming call has been placed to the telephone line. In response to the received signals, the modem controls the CO simulator to ring the extensions. The modem further comprises a relay which couples the first conductor pair to the second conductor pair when the modem is on hook with respect to the second conductor pair, thereby enabling normal speech communications to be performed by the subscriber on the telephone line. The relay couples the first conductor pair to the CO simulator when the modem is off hook with respect to the second conductor pair, thereby enabling the CO simulator to ring the telephones. In an alternate embodiment, the relay is comprised within an external wiring device coupled between the modem and conductor pairs and also includes a ring generator to alleviate the modem from having a ring generator for low power or real estate-constrained applications, such as in a notebook computer.

A system and method for enabling a remote user to maintain a virtual presence at a corporate office and behave substantially as if the user were physically present at the corporate office. First the remote user establishes a virtual presence connection at the corporate office, including providing identification and security information. Once the remote user is connected, the virtual presence server instructs the corporate PBX to automatically forward all calls to the remote user. The virtual presence server also routes email, faxes, and LAN data to the remote user. The virtual presence server also extends the corporate PBX and corporate LAN features to the remote user, just as if the remote user were physically located in the corporate office. According to the invention, the remote user makes outgoing telephone calls, sends faxes, transmits data, sends email and performs Internet access as if the remote user were physically present in the corporate office. The virtual presence server and/or the user communication device also performs a call forwarding operation to call forward telephone calls made to the user's home to the virtual presence server at the corporate office. These calls are then routed through the virtual presence server to the user's home. Thus the user can receive home telephone calls while the user is connected to the corporate office, wherein the home telephone calls are received on the same telephone line which is being used for the virtual presence connection.

A modem normally adapted for use on the PSTN communicates with a radio transceiver, typically a cellular telephone via an interface. The interface is coupled to the modem to communicate audible frequency computer data, control signals and status signals. The interface converts the audio-frequency control signals from the modem into binary signals for the radio transceiver and converts status signals from the radio transceiver to audible-frequency control signals detectable by the modem.

Method and apparatus for communicating data over a radio transceiver

The disclosed data communication equipment (DCE) provides full-duplex, split-speed data communication over 2-wire dial-up telephone circuits, typically between a host processor and data terminal equipment (DTE). A telephone line interface includes low speed and high speed modems that establish a low-speed DTE-to-Host communication channel and a high-speed Host-to-DTE communication channel for split-speed full-duplex data communication. An I/O interface interfaces the DCE to the Host/DTE I/O ports at selectable asynchronous I/O speeds (typically symmetrical). A communications processor provides buffering and control functions, and implements split-speed data communication in accordance with the high-speed and low-speed communication protocols. In addition, the communication processor provides data compression for the high-speed channel, and error checking and retransmission for both the high speed and low speed channels. The DCE telephone line interface network is switchable between Host and DTE modes.
