1. A method for establishing an intersubnet shortcut virtual channel connection (VCC) in an asynchronous transfer mode (ATM) communications network, comprising:

  • registering an association between a MAC/ATM address pair and the intersubnet shortcut virtual channel connection (VCC), the MAC/ATM address pair having a MAC address and an ATM address;

    receiving a first data frame being sent from a first station to a second station, wherein the second station is addressed using the MAC address;

    creating a second data frame in response to receiving the first data frame, wherein the second data frame has as a source address the MAC address; and

    sending the second data frame to the first station, wherein devices associated with the first station learn an origination point for the second station and can issue messaging necessary to establish the intersubnet shortcut VCC.
