Abstract:
For use with a packet transport network having first and second packet networks employing first and second transport protocols, respectively, a link layer device, comprising:a first protocol subsystem configured to receive and transmit packets in said first transport protocol over said first packet network; a physical layer device subsystem coupleable to a physical layer device associated with said link layer device, said physical layer device subsystem configured to translate said packets between said first and second transport protocols and communicate with said physical layer device employing flow control, said second transport protocol includes a packet control status with a channel number indicator that accommodates a channel number greater than 256; and a channel memory subsystem, associated with said first protocol subsystem and said physical layer device subsystem, configured to buffer said packets in a channel storage area on a per channel basis for transmission by said link layer device over one of said first and second packet networks.
