Abstract
A data processing apparatus, having an overhead branching unit configured to branch a signal data into an overhead and signal data; a control unit configured to retain the overhead; a time slot interchange unit configured to perform time slot interchange on the signal data; and an overhead insertion unit configured to insert the signal data and the overhead output from the time slot interchange unit and outputting as signal data.
Claims8
A data processing method comprising:
- inputting a signal data with a plurality of time slots;
- demultiplexing the signal data into an overhead and data for each time slot;
- retaining the overhead for each time slot;
- interchanging the data of different time slots;
- and
- combining the overhead with the interchanged data.
3 more elements
A data processing method comprising:
- fixing the overhead of a signal data to a constant value;
- providing the signal data to a time slot interchange unit that interchanges data of different time slots;
- and
- multiplexing the signal data subjected to the time slot interchange by the time slot interchange unit.

A data processing apparatus comprising:
- an overhead branching unit configured to branch a signal data into an overhead and signal data;
- a control unit configured to retain the overhead;
- a time slot interchange unit configured to perform time slot interchange on the signal data;
- and
- an overhead insertion unit configured to insert the signal data and the overhead output from the time slot interchange unit and outputting as signal data.
2 more elements
A data processing apparatus comprising:
- an overhead branching unit configured to extract an overhead of a signal data, and to rewrite the overhead of the signal data to a constant value;
- a time slot interchange unit configured to interchange data of different time slots of the signal data;
- and
- an overhead insertion unit configured to rewrite an overhead of the signal data output from the time slot interchange unit with the extracted overhead.
