SS7 Training Overview:

SS7 Training Overview or Signaling System #7 Training Course with Hands-On Exercises (Online, Onsite, and Classroom Live)

Signaling System No. 7 is commonly known in North America as SS7 and elsewhere throughout the world as C7. SS7/C7 is a system used to implement signaling and protocols for telecommunications networks. SS7 supports both fixed-line and cellular networks. In recent years, expanded telecommunications services have resulted in the introduction of additional SS7 protocols and functionality.

The SS7 Training Overview course introduces the basic concepts on the first day. The more complex features of SS7 level 4 protocols are covered on day two following a thorough coverage of the underlying material on SS7 levels 1, 2, and 3. In this 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. The SS7 Training Overview course explains the fundamental differences between the SS7 ITU-T and ANSI standards as well as the connection and connectionless signaling services. You will discover how SS7 supports cellular services such as subscriber roaming and packet-switched data services.
