SS7/C7 is a system used to implement signaling and protocols for telecommunications networks.  Signaling System No. 7 is commonly known in North America as SS7 and elsewhere throughout the world as C7.  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 Protocols and System Operation Training course presents the basic SS7/C7 concepts on the first day.  The more complex features of SS7 level 4 protocols are covered on day two.  Day three covers the newer and more advanced services including Advanced Intelligent Network (AIN) and Transaction Capabilities Applications Part (TCAP) message structures and architecture.

In this SS7 Protocols and System Operation 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. The SS7 Protocols and System Operation 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.

The SS7 Protocols and System Operation Training course begins with several topics which explain the purpose of lower-level signaling protocols MTP1, 2, and 3 including error control and network performance monitoring.  Day three introduces the more advanced signaling and database query functions performed in compliance with AIN and non-circuit-related transactions.
