  • System and method for multiplexing a frame relay virtual circuit and for performing non-disruptive diagnostics through a circuit using asynchronous transfer mode
    Patent number: 6269082
    Abstract: The present invention relates to a system and method for creating multiple logical channels across a single virtual circuit on a hybrid asynchronous transfer mode (ATM)/frame relay network and an ATM network. The logical channels include a single primary channel and multiple secondary channels. The secondary channels are created by the addition of a secondary channel flag and secondary header to the user information field of the data frames transmitted. Also, one of the secondary channels is designated as a diagnostic channel for conducting diagnostics across the virtual circuit. The diagnostic channel is reserved exclusively for diagnostic data traffic from an ATM digital service unit (DSU) to a frame relay DSU, or in the alternative, to a second ATM DSU.
