First Claim
Patent Images
1. A method using a communications device to interface a plain old telephone system (POTS) terminal, which includes a dial-up modem to transmit data, to a communications network, including:
- initiating a communications host session between the communications device and a communications host, prior to locally generating a connect sequence;
locally generating a connect sequence between a POTS terminal and a communications device, whereby the communications device appears to the POTS terminal to be a modem accessed via a telephone network;
locally decoding and encoding communications with the POTS terminal, including recovering digital data from a modem carrier signal received from the POTS terminal; and
conducting a packet-based session between the communications device and an application host through the communications host using the recovered digital data.

8. A method using a communications device to interface a plain old telephone system (POTS) terminal, which includes a dial-up modem to transmit data, to a communications network, including:
-
initiating a packet-based communications host session between a communications device and a communications host; detecting dialing by a POTS terminal coupled to the communications device; initiating an application host session between the POTS terminal and an application host, through the communications host; decoding and encoding communications with the POTS terminal, including recovering digital data from a modem carrier signal received from the POTS terminal, wherein the communications device appears to the POTS terminal to be a modem connected to the POTS terminal via a telephone connection; and conducting the application host session using the recovered digital data; further including connecting multiple communication devices through a packet concentrator linked to the communications host, wherein the packet concentrator and communications host are configured to reduce a number of sockets required to maintain a plurality of communications device-to-communications host links through the packet concentrator. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method of supporting a communications device coupled to a POTS terminal, which includes a dial-up modem to transmit data, including:
-
establishing a packet-based communications host session between a communications host and the communications device; establishing an application host session with an application host; receiving packets from the communications device containing data decoded from modem-based communications between the communications device and the POTS terminal; and conducting the application host session between the communications device and the application host; wherein the packet-based communications host session between a communications host and the communications device is conducted through a packet concentrator, wherein the packet concentrator and communications host are configured to reduce a number of sockets required to maintain a plurality of communications device-to-communications host links through the packet concentrator. - View Dependent Claims (19, 20, 21)

22. A method of conducting plain old telephone service (“
- POTS”
) terminal sessions using a network other than a public switched telephone network (“
PSTN network”
), without modifying the POTS terminal, including;connecting the POTS terminal to a local communications device; detecting a dial tone provided by the local communications device; dialing a host phone number; and communicating through the local communications device, as if the local communications device were a modem accessed via a PSTN network, with a host application identified to the communications device by the host phone number; wherein the local communications device acts as a packet concentrator, reducing a number of sockets required to maintain a plurality of POTS terminal-to-application host links through the packet concentrator. - View Dependent Claims (23, 24, 25, 26, 27, 28)
