Apparatus, and a method for flexibly switching telecommunication signals. A plurality of input bit streams are connected to a telecommunications switching network fabric element comprising a microprocessor system including memory. The microprocessor system, under program control, performs switching and protocol conversion functions on the input streams in order to generate output streams. Advantageously, a single element is able to concurrently switch input signals in a variety of protocols, including circuit switching protocols, such as Pulse Code Modulation (PCM), and packet switching protocols, such as Asynchronous Transfer Mode (ATM) protocols and Internet Protocol, (IP). Where desirable, the microprocessor system can also control the protocol conversion of input signals in one protocol to output signals in another protocol.
