Abstract

The present invention includes a method, system and apparatus for processing information bits in a telecommunications system. A network element receives the information bits into a physical port and then forwards the information bits to a MUX through an internal connection. The MUX receives the information bits from the physical port and then forwards the information bits to a functionality element through an internal connection. The functionality element receives the information bits from the MUX and then forwards the information bits to the MUX through an internal connection. The MUX receives the information bits from the functionality element and then forwards the information bits to the physical port.

Claims

1. A communication interworking device comprising:

a communication port;

a multiplexer;

an interworking element;

a port connection connecting the communication port and the multiplexer; and

a plurality of element connections connecting the multiplexer and the interworking element;

the communication port configured to receive a user communication having a first protocol and transfer the user communication having the first protocol over the port connection;

the multiplexer configured to receive the user communication having the first protocol and transfer the user communication having the first protocol over one of the plurality of element connections;

the interworking element configured to receive the user communication having the first protocol over the one of the plurality of element connections, convert the user communication having the first protocol to the user communication having a second protocol, and transfer the user communication having the second protocol over another one of the plurality of element connections;

the multiplexer configured to receive the user communication having the second protocol and transfer the user communication having the second protocol over the port connection; and

the communication port configured to receive the user communication having the second protocol and transmit the user communication having the second protocol.

2. The communication interworking device of claim 1 wherein the first protocol comprises asynchronous transfer mode (ATM) and the second protocol comprises time division multiplexing (TDM).

3. The communication interworking device of claim 1 wherein the first protocol comprises asynchronous transfer mode (ATM) and the second protocol comprises frame relay.

4. The communication interworking device of claim 1 wherein the first protocol comprises a packet-based protocol and the second protocol comprises a non-packet-based protocol.
