Abstract
A method is described for transmitting digital data using the time-division multiplex method, in which the data are transmitted within a sequence of time frames (82, 84). In each time frame (82, 84), at least the number of transmitted data bits matches the option defined in the ISDN Standard for 2B1Q transmission. However, a plurality of time frames (82, 82), which form an overall frame (80), are transmitted within the time which is specified by the ISDN Standard for the transmission of an ISDN Standard time frame (60).
Claims14
A circuit arrangement for transmitting data, comprising:
- a receiving unit for receiving useful data which have been produced when using at least one transmission service for transmitting data,
- a frame producing unit for producing a time sequence of useful data, wherein a number of individual data containing frames configured in accordance with ISDN standards are produced,
- an output unit for transmitting the data, wherein said output unit transmits an overall frame formed from a plurality of the individual frames within a time that corresponds to the ISDN standard transmission time for transmitting a single ISDN frame;
- a frame identifier associated with at least one overall frame in a sequence of transmitted overall frames, the frame identifier indicating which portion of said plurality of individual time frames form each of said overall frames in said sequence.
A method for transmitting digital data using a time-division multiplex method, comprising the steps of:
- transmitting data bits within a sequence of individual time frames, wherein the number of data bits being transferred in each time frame corresponds to the ISDN Standard for the number of bits forming a time frame;
- transmitting overall frames, each comprising a plurality of said individual time frames within the time which is specified by the ISDN Standard for the transmission of an ISDN time frame;
- and
- using a frame identifier, which is contained within at least one overall frame in a sequence of transmitted overall frames, the frame identifier indicating which portion of said plurality of individual time frames form each of said overall frames in said sequence.
