System and method of communication using at least two modulation methods

Abstract

Methods and systems are provided for simple cable phone and internet (SCPI) device that may be coupled with a cable modem (CM) and one or more SCPI head ends, e.g., via an SCPI access point. The CM may be capable of communicating a first modulated signal with a cable modem termination system (CMTS), via the SCPI device. The SCPI device may be capable of combining a second modulated signal to the first modulated signal thereby generating a combined signal. The SCPI device may be capable of sending the combined signal comprising the first modulated signal and the second modulated signal to the CMTS and an SCPI head end. The SCPI head end may be capable of processing the combined signal and extract information and/or data associated with a service. The SCPI head end may deliver the extracted information and/or data to an appropriate gateway.

What is claimed: 
     
         1 . A communication system comprising:
 a simple cable phone and intern& (SCPI) head end device coupled with one or more gateways, wherein the SCPI head end is capable of receiving a combined signal from an SCPI device;   the SCPI head end capable of separating a modulated signal from the received combined signal;   the SCPI head end capable of extracting information and data associated with a service;   the SCPI head end capable of directing the extracted information and data associated with the service to one of the coupled gateways.   
     
     
         2 . The system of  claim 1 , wherein the combined signal is received from an SCPI access point. 
     
     
         3 . The system of  claim 1 , wherein the coupled gateways comprise one or more of a plain old telephone service (POTS) gateway, a voice over intern& protocol (VOIP) gateway, or a data gateway. 
     
     
         4 . The system of  claim 1 , wherein the combined signal comprises a first modulated signal and a second modulated signal. 
     
     
         5 . The system of  claim 4 , wherein the second modulated signal is embedded within the first modulated signal. 
     
     
         6 . The system of  claim 4 , wherein the second modulated signal is received during a silence period.
