Abstract

An apparatus for establishing a data communication link with a plurality of other modems on telephone line is disclosed. The Frequency-Division Multiplexing (FDM) compliant modem of the present invention for establishing a data communication link with a plurality of other FDM compliant modems on a telephone line comprises a means for transmitting data on a first modulation band on the telephone line and a means for receiving data on a plurality of distinct modulation bands on the telephone line. The present invention also includes a system for linking a plurality of FDM compliant modems in a multiple site configuration on a telephone line, the system comprising a plurality of FDM compliant modems, each modem of the plurality of modems transmitting data on a distinct modulation band and receiving data on at least two other modulation bands.

Claims

1. A system for linking a plurality of Frequency Division Multiplexing (FDM) compliant modems in a multiple site configuration on a telephone line, said system comprising:

a plurality of FDM compliant modems having a computer is coupled to each modem of said plurality of modems, each modem of said plurality of modems transmitting data on a distinct modulation band and receiving data on at least two other modulation bands, wherein said each computer includes;

means for playing a multiple player video game;

means for collecting game statistics while or after said multiple player video game is played;

means for establishing a communication link with a server via said telephone line; and

means for transferring said game statistics to said server.

2. The system as claimed in claim 1 wherein each computer further includes means for delaying transmitted or received data.
