SS7 real message communication tutorial design using ASP.NET - Call Flow 1

Abstract

This is a real telecom message call flow to be send through a socket in hex format and decoded as per standard TCAP/ISUP message decoding standards. This will be used for developers to do a load test for their TCP/IP sockets message handling capability.

The messages should be properly explained from a Telecom Standards
A help file should be provided to explain the message decoding logic.
Only a specific decoder for this particular message should be used. No complex generic decoders using TCAP/ISUP message library is required.
ASP.NET and call flow JPEG files shall be used for a better picture based Training.
