    Abstract: PROBLEM TO BE SOLVED: To enable access to all the time slots of a TSI by storing a packet in a packet assembler-inverse assembler, transmitting it and directly connecting a processor for inserting the output packet to an output buffer to the memory of the TSI. SOLUTION: A trunk time slot stores a PCM signal 203 and sends the packet to a RAM 211 for assembling/inversely assembling it. A line time slot is sent to a modem signal processor 201, analog PCM data are transformed to digital data to be used for the RAM 20, and the digital data in the RAM 211 are transformed to analog PCM data for transmission to the line time slot. The packet assembled or inversely assembled by the RAM 211 is changed so as to have a data address by a routing processor 213 and stored in a TSI start interface 105. Thus, the ATM network is directly interfaced while using the ATM interface 221.

    Abstract: A large router for routing datagrams. The large router comprises a plurality of router slices, each of which receives switches and transmits datagrams. Each router slice has a routing memory for routing the packets. If a packet is received whose destination address is not known to the receiving packet slice, the packet slice broadcasts a request for routing information for that datagram to the other packet slices of the large router and routes the packet in accordance with the received responses. Groups of slices are interconnected by a time slot interchange (TSI) unit, and groups of TSIs are interconnected by a time multiplexed switch. The router can consist of more than one switch; the switches being interconnected by high speed data links. Advantageously, the router, though composed of small slices, acts as if it were a single large high capacity entity.

    Abstract: Apparatus and a method for interfacing between the Internet and the Telephone Network. A time slot interchange (TSI) is enhanced by the addition of a supplementary memory (211) 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 (213), 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 (301) can be inserted between the TSI memory (103), and the supplementary memory to convert PCM voice samples into vocoded voice samples for transmission over the Internet. A modem signal processor (201) 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.
