ABSTRACT:
A switch switches time division multiplexed (TDM) data and packet data from input ports to output ports. The swich comprises: a plurality of input ports receiving data, wherein each data comprises either TDM data or packet data; a plurality of output ports transmitting switched data; and a shared memory coupling the input ports to the output ports. The shared memory sequentially receives the data from the input ports, and switches a sequentially received data from a respective input port to a respective output port. Switching of packet data by the shared memory has no latency or jitter effect on switching of TDM data by the shared memory.
