SS7 Training In-Depth:

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 SS7 Training In-Depth 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.

• 4 days of  SS7 Training In-Depth with an expert instructor
• SS7 Training In-Depth Electronic Course Guide
