SS7 Training Courses in the UK (C7)
Signalling System 7 (signaling system #7, signalling system #7, SS7, C7) is the main architecture used for out-of-band signalling in digital telephone networks.
This course provides a comprehensive overview of the ITU Signalling System No.7 (SS7 / C7), including the procedures for setting-up, managing and clearing down calls between users, C7 principles and higher level protocols.
The course covers current terminology, management and future applications, and is essential for delegates wanting to learn the basics of C7, its capabilities and its use.
