Abstract: A method and apparatus for transmitting signals at different rates between an originating device and a destination device. The originating device generates a communication signal, including routing data, for transmitting the communication signal at a native rate associated with the originating device. The communication signal is received by a switch which analyzes the routing data of the signal to identify transmission rates recognizable by the destination device and, if necessary, a transmission path for routing the signal across a backbone network at the native rate. The system then determines whether to re-encode the signal for direct transmission at a different rate recognizable by the destination device, or to maintain the signal at the native rate for transmission either directly to the destination device or across the backbone network. The signal is then transmitted.
