Please find a version of Tun&H.246.doc and Tun&H.246.zip that I have uploaded into ftp://standard.pictel.com/avc-site/Incoming/ for the washington meeting Apr 21.
Summary This contribution discusses a framework for transporting signaling protocols (SS7, TCAP, ISDN, QSIG and DPNSS) over IP packet networks. The framework is referred to as signaling 'backhaul'. The backhaul or tunneling takes place between a Media Gateway (MG) and/or Signaling Gateway (SG), which interfaces between the circuit world (PSTN) and the IP packet world GateKeeper (GK) 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 and/or Gatekeeper. Annex A provides a overview how the RAS messages may interwork INAP.
