Method of transmitting control data or source data in a format not dependent on a format used for the common transmission of control data and source data

In a method for the common transmission of digital source and control data between a plurality of subscribers connected through a network in a communications system, for an unformatted transmission of data from one subscriber to another subscriber through the network, which includes converting the source and control data into a given transmission format prescribing a clocked sequence of individual bit groups of equal length in a continuous data stream synchronized to a common clock signal for forming formatted data, the improvement which comprises:

• reserving at least one bit position in each bit group for inserting unformatted data, allocating the unformatted data bitwise to the reserved bit positions of successive bit groups, assigning the unformatted data to a certain subscriber as a function of a separate control datum, and transmitting, within the individual bit groups, the formatted data and the unformatted data.

In a method for the common transmission of digital source and control data between a plurality of subscribers connected through a ring-like network in a mobile communications system for an unformatted transmission of data from one subscriber to another subscriber through the network, which includes converting the source and control data into a given transmission format prescribing a clocked sequence of individual bit groups of equal length in a continuous data stream synchronized to a common clock signal for forming formatted data, the improvement which comprises:

• reserving at least one bit position in each bit group for inserting unformatted data, allocating the unformatted data bitwise to the reserved bit positions of successive bit groups, assigning the unformatted data to a certain subscriber as a function of a separate control datum, and transmitting, within the individual bit groups, the formatted data and the unformatted data.

In a method for the common transmission of digital source and control data between a plurality of subscribers connected through a ring-like network in a stationary communications system for an unformatted transmission of data from one subscriber to another subscriber through the network, which includes converting the source and control data into a given transmission format prescribing a clocked sequence of individual bit groups of equal length in a continuous data stream being synchronized to a common clock signal for forming formatted data, the improvement which comprises:

• reserving at least one bit position in each bit group for inserting unformatted data, allocating the unformatted data bitwise to the reserved bit positions of successive bit groups, assigning the unformatted data to a certain subscriber as a function of a separate control datum, and transmitting, within the individual bit groups, the formatted data and the unformatted data.
