Patent ID: 6963569

Claim:
A device for interworking asynchronous transfer mode cells, comprising: a transmission convergence sublayer operable to receive one or more traffic streams, the transmission convergence sublayer being operable to identify a selected one of the one or more traffic streams carrying asynchronous transfer mode cells; and an encapsulation unit operable to receive the selected traffic stream carrying the asynchronous transfer mode cells identified by the transmission convergence sublayer, the encapsulation unit being operable to encapsulate the traffic stream carrying the asynchronous transfer mode cells into an encapsulated frame having a protocol format readable by a serial communications controller that receives the encapsulated frame, wherein the transmission convergence sublayer is operable to have traffic in the selected one of the one or more traffic streams not carrying asynchronous transfer mode cells be provided to the serial communications controller without being encapsulated by the encapsulation unit.
