Abstract:
A method for overcoming long delays in the transmission between two fax machines connected for fax transmission, comprising:dividing a connection between a calling fax machine and a called fax machine into at least two separate connections by an interceptor, wherein the interceptor operates as a fax receiver and a fax transmitter tied together by internal communication; buffering, by the interceptor, data transmitted from the calling fax machine; transmitting, by the interceptor to the called fax machine, a fax front page explaining any added delays; transmitting an illegal training sequence from the interceptor to the called fax machine; transmitting from the called fax machine, in response to the illegal training sequence, a failure to train signal; and waiting, by the called fax machine, reception of a digital command signal from the calling fax machine, wherein, if there is a training problem from the calling fax machine to the interceptor, sending a troubled training signal continually to the called fax machine until a failure to train signal is returned therefrom, a failure to train signal having already been sent to the calling fax from the interceptor.
