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.
