The SG function may also be coresident with the MG function to process SCN signaling associated with line or trunk terminations controlled by the MG (for example, signaling backhaul). A Signaling Gateway could be modeled as one or more Signaling Gateway Processes, which are located at the border of the SS7 and IP networks.
