Abstract
A switching unit for a telecommunication network, such as an SDH telecommunications network, comprises a command controlled switching matrix having at least two switching degrees of freedom and a control logic for generating a first type of control commands which, for a group of connections, define the switching thereof in a first degree of freedom, and at least a second type of control commands which specify, for a given connection, the switching thereof in all degrees of freedom. Between the control logic and the switching matrix, a conversion circuit there is operative for combining control commands of the first type with control commands of the second type into a control command of the second type.

A switching unit for a telecommunication network, comprising:
- a) a command controlled switching matrix having at least two switching degrees of freedom;
- b) a control logic for generating a first type of control commands that determine, for a group of connections, the switching of these in a first switching degree of freedom, and at least a second type of control commands which define, for a given connection, its switching in all the switching degrees of freedom;
- and
- c) a conversion circuit connected between the control logic and the switching matrix for combining control commands of the first type with control commands of the second type into a control command of the second type.
A method of switching in a telecommunication network, comprising the steps of:
- a) generating a first type of control commands which, for a group of connections, specify the switching thereof in a first degree of freedom, and at least a second type of control commands which, for a given connection, specify the switching thereof in all degrees of freedom;
- b) combining the control commands of the first type with control commands of the second type, and forming a control command of the second type;
- and
- c) inputting the control command obtained by the combining step into a command controlled switching matrix having at least two switching degrees of freedom.
