METHOD AND APPARATUS FOR SWITCHING DATA

摘要

An apparatus is provided for switching data between input and output lines. The input and output lines are coupled to a number of line termination boards which are interconnected by a network. The line termination boards comprise a data block processor which for each switch interval combines data from the input connections (such as time slots) associated with output lines of another line termination board and an interface for transmitting the combined data to these over the network. A mapping processor generates mapping data that maps data of the combined data to the output connections. The mapping data is transmitted to the receiving line termination board which comprises a de-mapping processor which allocates data of the combined data to the appropriate output connections in response to the mapping data.
