Abstract
A telecommunications switch which has a central switch fabric made up of multiple crossbars that can be used to switch either circuit switched or packet switch communications as long as appropriate input and output interfaces and controllers are provided. Thus, a large, high throughput telecommunications switch is provided where the expensive switch fabric core can remain the same and the interfaces and control cards changed as the relative demands for circuit switched communications and packet switched communications, such as ATM, evolve. Besides being flexible, this switch may also be fault tolerant.
