摘要：
A system and method for interworking between FR (frame relay) and ATM (asynchronous transfer mode) using permanent virtual circuits. An ATM VCC between two interworking functions is dedicated to FR LMI signalling traffic, while the FR data traffic is carried by ATM VCCs which do not carry any FR LMI signalling traffic. The FR data traffic of a given FR DLCI is carried by an ATM VCC having a service category and bandwidth parameters which reflect the transfer priority and bandwidth needs of the particular FR DLCI. This allows a high priority to be assigned to all LMI traffic carried over the ATM network independent of the priority assigned to the FR data traffic.
