Wideband/multislot switching arrangement

A wideband/multislot switching arrangement is provided for use in a digital telecommunications exchange. A call handling device is provided which receives signalling information about a path connection, and which communicates with a switch interface to generate a single switch request. The switch interface includes a map record of each circuit connection controlled by the call handling device and generates multiple switch requests which are used to control a number of switches to make the path connections.

We claim:

1. A wideband/multislot switching arrangement, for use in a digital telecommunications exchange including a call handling device controlling circuit connections of a physical switch assembly and a switch interface in communication with the call handling device, the switch interface includes means for storing a map record of each of the circuit connections controlled by the call handling device and available services at the respective circuit connections, said call handling device including means for receiving signalling information about paths established by said circuit connections and means generating a single switch request presented to the switch interface for addressing the map record storing means and rendering the switch interface operative to generate multiple switch requests to control the physical switch assembly in establishing the paths.

2. A wideband/multislot switching arrangement as claimed in claim 1, wherein said map record storing means stores data relating to the available services and service layers and selecting one of the available services required.

3. A wideband/multislot switching arrangement as claimed in claim 2, wherein said map record storing means further stores data relating to service layer bandwidth representing the number of 64 Kbit/s to 2 Mbit/s channels available at each of the service layers.

4. A wideband/multislot switching arrangement as claimed in claim 2, wherein said map recording storing means further stores data relating to a service layer index identifying a first entry of the service layer data and identify actual timeslots for the established paths.

5. A wideband/multislot switching arrangement as claimed in claim 4, wherein the data relating to the service layers identifies actual channels in each of the service layers.
