This first section outlines the basic signalling functions found in
telecoms. In particular it looks at signalling functions, in band
and out band signalling, and Common Channel Signalling (CCS).
Outlining the principles of Call routing, Numbering schemes, SS7
architecture and network topology and OSI equivalence. Also
introduces Service Switching Point (SSP), Signal Transfer Point (STP),
Service Control Point (SCP) and Intelligent Peripherals (IP).
Outlines the Signalling links involved with SS7 from Link A to Link
Message Transfer Part
Introduces the elements of the SS7 Protocol Stack, focusing on the
Message Transfer Part (MTP1, MTP2 and MTP3). Topics covered are HDLC/MTP2
comparison, Error rate Detection/Monitoring and Retransmission,
Signalling Network Functions, Signalling Message Handling and
The section outlines the higher levels within SS7, including the
ISDN User Part (ISUP), Signalling Connection Control Part (SCCP) and
the Transaction Capabilities Application Part (TCAP).
Intelligent Networking (IN)
Outline of the IN concept and standards. Number translation
examples, Services and Features of IN, definition of SIBs, FEs and
ASEs. Relationship between INAP and CAMEL.
