( Duration: 2 Days )

The SS7 training course provides a thorough introduction to SS7. Signaling System #7 is the hands-down choice for engineers, network managers and other professionals everywhere. It gives you a bedrock understanding of the signaling network, its architecture, and the protocols used to communicate through it and its evolution to next generation networks. Topics such as SIGTRAN, IMS and SIP are also covered.

The SS7 or Common Channel Signaling System No. 7 (i.e., SS7 or C7) is a global signaling standard for telecommunications defined by ITU-T specifying the procedures and mechanisms to call setup, routing and control over PSTN and Mobile networks. Example of applications using SS7 are: PSTN and cellular networks (i.e. GSM, CDMA) call setup, management, and tear down, LNP, toll-free calls, wireless roaming, IN/AIN and CAMEL.

By attending SS7 workshop, Participants will learn:

  • Basic concepts behind SS7 (Signaling System 7) Protocols and Network Architecture
