Abstract:
A data communication method includes the steps of: sending a communication procedure signal prior to data communication; sending a data signal; and sending a stop signal for stopping an echo suppressor function on a communication network; wherein the stop signal is sent prior to the data signal in such a way that a time interval during which no signal is generated does not occur, after the stop signal is sent, until the data signal is sent. A data communication apparatus includes: a communication unit for sending and receiving a data signal; a discrimination unit for discriminating if the apparatus is a calling station; and a control unit for controlling to change a communication controlling mode based on the output from the discrimination unit.
Abstract:
A universal serial bus (USB) device and a method of recognizing a USB mode whereby the USB device automatically recognizes a mass-storage or PictBridge mode according to a type of a connected host such that the USB device configures a communication interface suitable for the recognized host. The USB device includes: a controller to control a USB communication with the host; and an interface unit to automatically determine a mode of the USB communication, from among a plurality of modes, according to a type of the connected host, and to provide a communication interface in the determined mode corresponding to the host. Although the host connected to the USB device does not support several configuration descriptors, a timer of a mass-storage module switches a current mode to the USB mode suitable for a corresponding host, such that the USB device universally supports the USB multi-mode irrespective of host types.
Abstract:
A method compatable with the multiple fax and data modem protocols to determine if a session originating terminal is a fax terminal or a data terminal without user intervention while allowing data terminals to operate at the highest possible speed. Further, there is a method of providing improved internetworking of fax machines over links that include relay technology.

Abstract:
Disclosed herein are systems and methods that can improve the quality and efficiency of document facsimile transmission. Quality can be improved by allowing a facsimile document sender to view the document as it will be transmitted to a receiving facsimile device. Efficiency of facsimile transmission is improved by providing systems and methods that allow the transmitting facsimile device to determine the capabilities and/or preferences associated with the receiving facsimile device and convert the facsimile document to match those capabilities and/or preferences before a call is placed.
