<p>A method and apparatus for switching data between one or more first TDM interfaces and one or more second TDM interfaces. Data words are sequentially received from the first TDM interface (45) and are stored in a first memory (41) in a predetermined order. Each stored data word is written out of the first memory to a back plane bus (35) in the predetermined order. Each data word on the back plane bus is read to a second memory (41) such that each data word is stored at a location corresponding to a time slot during which such data word is on the back plane bus. Each data word stored in the second memory is read to the second TDM interface (47) in a predetermined order.</p> |
