This Internet Draft discusses a framework for transporting signaling protocols (SS7, ISDN and DPNSS) over packet networks. The framework is referred to as signaling 'backhaul'. The backhaul takes place between a Media Gateway (MG) or Signaling Gateway (SG), which interfaces between the circuit world (PSTN) and the packet world (IP/ATM), and a Media Gateway Controller (MGC), which provides call processing. It is referred to as 'backhaul' because the gateway terminates the lower layers of the protocol (i.e. Layer 1 and 2) and backhauls the other layers to the MGC.
