>As SS7 is merely a message transport protocol

SS7 is not a message transport protocol. TCP/IP is a message transport protocol. SS7 layers 1,2, & 3, are the MTP layers (Message TRansport Protocol). In addition, SS7 contains TCAP (Transaction capabilities Application Part), ISUP (ISDN USer Part), SCCP (Signaling conection control part), and OMAP (Operations, Maintenence, and Administrations Part).

The MTP portion of SS7 is very similar to TCP/IP, and the upper layers could easily be implemented on TCP/IP. However, it is the entire SS7 implementation that provides for a highly reliable and flexible NW architecture that is suitable for our telephone NW backbone.
