  • Patent number: 6661880
    Abstract: Systems and methods for embedding, detecting and extracting access information from a dial tone of a private branch exchange system. The access information is embedded at the zero crossings of the dial tone. This has a minimal effect on the audible quality of the dial tone. A connecting device, such as a modem, receives the altered dial tone having access information. The access information is extracted by the connecting device and displayed to a user. The access information is automatically downloaded by the connecting device upon connecting to the private branch exchange without interaction from a user by having the connecting device go off hook such that the dial tone is received. The connecting device detects, extracts and displays the access information. After the access information is displayed to a user, the connecting device can await further user interaction or immediately make use of the access information.

  • Patent number: 6055245
    Abstract: An apparatus and method for facilitating interaction during a communication session between an analog modem and a terminal adapter for conveying digital alert tones and control data therebetween is provided. The embodiments provide for a collateral digital communication path between a microcontroller of an analog modem and a microcontroller of a terminal adapter for selectively relaying digital alert tones and control data therebetween. One embodiment utilizes a cellular interface of an analog modem for tapping and evaluating information for the presence of control data. Upon successful identification of control data, the microcontroller of a terminal adapter is notified and the specific control data detected in identified. By providing a method of apparatus for digitally relaying control data, accuracy of identification of control data by a terminal adapter is enhanced by foregoing needless signal transformation and retransformation.
