Abstract
Apparatus and a method for interfacing between the Internet and the Telephone Network. A time slot interchange is enhanced by the addition of a supplementary memory for storing data for accumulating Internet packets. When a packet has been accumulated, the appropriate header is inserted into the packet under the control of a routing processor, and the packet can then be sent as a group of adjacent PCM samples over a connection to the Internet. In other embodiments, information is sent to the Internet over a direct data pipe for transmitting ATM cells or Ethernet packets. A Vocoder signal processor can be inserted between the TSI memory, and the supplementary memory to convert PCM voice samples into vocoded voice samples for transmission over the Internet. A modem signal processor can be interposed between the TSI memory and the supplementary memory to convert between analog data (representing for example, shift key analog signals) and binary data for transmission within packets over the Internet. Advantageously, existing TSI units can be used to interface with both the telephone plant and the Internet.
