Course description
This online course provides a detailed treatment of the principles and operation of C7 signalling systems in both fixed and mobile telephony networks. Individual chapters explore the various aspects of this inter-exchange signalling system including use of C7 in the ISDN, the provision of advanced services and the use of C7 in mobile radio networks.
By the end of this course you will be able to:
- describe the advantages of Common Channel Signalling (CCS)and the role of the various components of a CCS signalling network.
- describe signalling message transfer with the Message Transfer Part (MTP) of C7.
- explain the importance of traffic management, link management and route management in the signalling network.
- describe the use of the ISDN User Part (ISUP) of C7 in fixed networks (ISDN and PSTN).
- describe the role and operation of the Signalling Connection Control Part (SCCP) of C7 with reference to information retrieval from remote databases.
- describe the role and operation of the Intelligent Network Application Part (INAP) of C7 with reference to the functional and physical elements of an Intelligent Network and the role and operation of INAP in advanced services such as number translation.
- describe the interconnection of signalling links between circuit-switched and voice over IP telephony networks.
- describe the use of the Mobile Application Part (MAP) of C7 in mobile networks.
This online course includes assessments, the results of which are summarised in a certificate published at course completion.
