Abstract
An Internet/telephone adapter device and method is provided to automatically detect the communication type of an incoming call. The Internet/telephone adapter device comprises an auto-detecting means for providing a mechanism to detect the communication type of an incoming call by means of the feature rings. The feature rings have a predetermined feature distinguishable from non-feature rings. Whenever the auto-detecting means determines the communication type of the incoming call, it sends a control signal to CPU. In response to the control signal, the CPU will automatically switch the linkage to the Internet or to the PSTNs without further human operations.
Claims13
An Internet/telephone adapter device comprising:
- interfacing means connected to a telephone line for bidirectionally transferring voice signals and command signals from said telephone line, and generating a notifying signal in response to a ring signal;
- a hybrid circuit coupled to said interfacing means for transferring a ring-back signal obtained from said command signals;
- first converting means coupled to said hybrid circuit for converting said command signals, said voice signals, and said ring back signal into digital command signals and digital voice signals, and digital ring-back signal;
- a digital signal processor (DSP) coupled to said first converting means comprising:
- a signaling means for receiving digital signals input from said first converting means;
- auto-detecting means for determining a communication type of an incoming call and generating a detection result;
- modulation/demodulation means for processing said digial command signals and said digital voice signals and performing Internet communication in response to said detection result;
- means for processing said digital voice signals;
- second converting means coupled to said digital signal processor for converting said digital voice signals, said digital command signals output from said digital signal processor into analog signal processor;
- and
- a central process unit (CPU) coupled to said digital signal processor for controlling a linkage between said telephone line and said internet in response to said detection result.
A method for auto-detecting a communication type of an incoming call, comprising the steps of:
- auditing an incoming call;
- determining if the sampled consecutive rings having intervals each longer than a predetermined period of time;
- determining said incoming call as an Internet call when said sampled consecutive rings having intervals shorter than said predetermined time, and complying with a predetermined feature;
- connecting to said Internet when the communication type of said incoming call is determined to be an Internet call;
- starting communication after connecting to said Internet;
- and
- disconnecting said Internet communication when said communication is finished.
A method for auto-detecting a communication type of an incoming call, comprising the steps of:
- a caller site:
- performing a dialing procedure;
- determining the communication type requested by the caller;
- performing regular telephone communication when determining said caller requests a regular telephone communication;
- performing Internet login procedure when determining said caller requests an Internet communication;
- waiting for a callee's response;
- start communication when said callee responses;
- and
- performing logout procedure when said communication terminates;
- a callee site:
- waiting for an incoming call;
- determining if sampled consecutive rings having intervals each being longer than a predetermined period of time;
- determining said incoming call is a telephone call when said sampled consecutive rings having intervals each being longer than said predetermined period of time;
- determining said incoming call as an Internet call when said sampled consecutive rings having intervals each being shorter than said predetermined period of time, and complying with a predetermined feature;
- connecting to said Internet when said incoming call is determined to be an Internet call;
- starting communication after connecting to said Internet;
- and
- logout from said Internet when said communication is finished.
