This course gives a complete overview of the SS7 structure, architecture and evolution, in fixed network and covers parts needed in mobile networks. The course explain all basic concepts and structure of a signaling network and is the starting point for everybody who wishes to work with signaling and implemented protocols in different networks both for fixed and mobile applications.
Explain the signaling concepts used in telephony networks
Explain the terms Inter-Exchange Signaling, Channel Associated Signaling, CAS, and Common Channel Signaling, CCS or SS7
Explain the relationship between the OSI model and Signaling System No.7, SS7, and the IP protocol suites
Explain the basic structure of SS7 and mention the most common application-layer protocols
Mention common SS7 network topologies
Explain the functions of (Level 2), Link Layer Transactions and (Level 3) MTP.
Explain the functions of Signaling Network Testing (SNT) and Management (SNM)
List the major functions of the ISDN User Part (ISUP) and TUP (Telephony User Part)
Draw the call set-up SS7 signal message flows
List the common SS7 messages and describe their functions
Explain the principles of routing of SCCP messages and SCCP addressing rules
Explain briefly, the SCCP management procedures
List the major functions of the Transaction Capabilities Application Part (TCAP)
List the main functions of Mobile Application Part, MAP
Explain the Intelligent Network (IN) structure and list the functions of the basic IN nodes
List the major functions of the IN Application Part and CAMEL Application Part, CAP
Briefly explain what is softswitch concept and the protocols needed for its implementation.
The course is designed for technical staff requiring an understanding of the Signaling System No. 7, SS7, in general and how SS7 is implemented in the core network architecture
The participants should have basic knowledge in telecommunications or data-communications. No previous signaling knowledge is required.
Duration and class size
The recommended length of the course is 4 days depending on the participants’ background. The maximum number of participants is 16. However it is easy to adapt the course length to the actual needs, thanks to the modular structure.
This course is based on theoretical instructor-led lessons given in a classroom environment.
