SS7 is a key element in the control plane of fixed and mobile networks and in Intelligent Network scenarios. It facilitates communication between SS7 hosted ‘applications’ enabling end-to-end service delivery. This course provides a comprehensive description of SS7 protocols, functions and procedures.
Those who need a detailed understanding of the implementation and functions of SS7.
An understanding of the PSTN architecture and circuit- and packet-switched concepts, together with a working knowledge of the OSI Model and primary rate (E1/T1) bearers.
