Method for using digital data networks for the transmission of data via voice connection paths

a digital data network and voice connection technology, applied in the direction of data switching by path configuration, telephonic communication, electrical equipment, etc., can solve the problems of not fully exploiting the theoretically possible useful data rate of a digital transmission link over which low-bit-rate data must be transmitted, and using the transmission capacity so utilized, etc., to reduce the data rate, reduce the cost, and increase the transmission reserve

Benefits of technology

This approach reduces bandwidth requirements by utilizing only the necessary bandwidth for data transmission, achieving a significant reduction in transmission costs and efficiency, particularly in high-cost connections, while ensuring secure and transparent data transfer.

Problems solved by technology

Owing to the limited worldwide availability of such networks, even today a multitude of data is still transmitted over analog voice connection paths.
This means that the theoretically possible useful data rate of a digital transmission link over which the low-bit-rate data must be transmitted is not fully utilized.
However, this is very disadvantageous when the transmission capacity thus utilized is particularly expensive, as is the case, for example, with satellite connections or overseas cables.
All these known methods suffer from the serious disadvantage that they are limited only to the transition between various services and to the conversion of individual services handled via a voice connection in the voice connection path.

Embodiment Construction

[0037]FIG. 1 shows a schematic representation of a prior art basic structure of data transmission in voice connection paths. The two terminals 1 are connected via an access line ASL to one of a plurality of exchanges 2. These exchanges are interconnected via voice connection paths ÜST. In order to set up a connection, usually one of the two terminals 1 sends its destination information to the corresponding exchange 2 which thereupon sets up a voice connection path ÜST between the two terminals 1. Owing to their technical construction, both terminals 1 are capable of coding the data for transmission in such a manner that it can be transmitted via a voice connection path. Such coding is based normally on multi-frequency tone signals of the kind known, for example, from multi-frequency tone dialing.

[0038]Usually, at the beginning of the connection, both terminals 1 test the characteristics of the voice connection path ÜST and of their own device type, in order then to agree interactive...

Abstract

A method for reducing bandwidth when transmitting data between a sending terminal and a receiving terminal over a voice connection path using a digital data network. The coding of user information is converted within the digital data network between data transmission in the voice connection path and data transmission in the digital data network so that the user information is transmitted on one section of the digital data network via the coded voice connection path and the user information is transmitted on another section of the digital data network using a method suitable for the digital data network.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a continuation of U.S. patent application Ser. No. 09 / 673,520, issuing as U.S. Pat. No. 7,512,152, which was the national stage of PCT / EP99 / 01284, filed on Feb. 27, 1999, which claimed priority to German Patent Application No. DE 19817007.6, each of which is expressly incorporated herein in its entirety by reference thereto.FIELD OF THE INVENTION[0002]The present invention relates generally to a method for using digital data networks, and in particular, to a method for reducing bandwidth when transmitting data between a sending terminal and a receiving terminal over a voice connection path using a digital data network.RELATED TECHNOLOGY[0003]For the purpose of data transmission, communication networks exist which are used exclusively for transmitting digitally coded data (data, voice, tone signals, images) between terminals, and which have been suitably optimized for this application purpose.[0004]Owing to the l...
