Introduction:

SS7 Training In Depth Course with Hands-On Exercises (Online, Onsite and Classroom Live)

Signaling System No. 7 (SS7), known as C7 outside North America, is a packet-based out-of-band signaling system that is used to implement circuit-switched telecommunications networks and supports both fixed-line and cellular networks. In recent years, additional SS7 functionality has been introduced to meet the needs of expanding telecom services.

In this in Depth SS7 Training course, you will learn the history of signaling and the progression of the technology through both in-band signaling and out-of-band signaling protocols. You will learn the key differences between the SS7 ITU-T and ANSI standards, connection and connectionless signaling services, and how SS7 supports cellular services such as subscriber roaming and packet-switched data services.

Covered in depth are the complex level 4 protocols, newer and more advanced services such as Advanced Intelligent Network (AIN), and Transaction Capabilities Applications Part (TCAP) message structures and architecture. A typical course is four days long but can be shortened to three or expanded to five depending on the level of depth required.

Duration: 4 days
