Abstract
Apparatus, and a method for switching digital signals of different protocols in a large switching network. Signals and different protocols are encapsulated in a common protocol by a set of input modules. The signals in the common protocol are then switched by a large central stage to a plurality of output modules, which then generate signals in the correct protocol. Narrow-band signals are converted into broadband signals, so that the central stage switches only broadband signals. This simplifies the design of the central stage, while still making it possible to have a very large and economical central stage switch. Advantageously, this arrangement allows a single large switch to switch large quantities of traffic in a plurality of protocols.
