After reading basic concept of SS7, we can see the seven layer of SS7. The first three Layer SS7 has function to assure reliability which is known as Message Transfer Part. Here we have
Signalling Data Link : Physical, Electrical and Procedural Characteristics.
Signalling Link : Error Detection/Correction,Sequencing, Alignment, Link Synchronization and Flow control
Signalling Network : Messages [...]
After discussing SS7 basic concept in signalling network, we continue about Signalling Point ( SP ) and further about Signalling Link, Signalling Linkset and Signalling Route in SS7 Network.
Just to the point, Signaling Point refers to the communication network node equipped with the SS7 system.
The SP is identified via the signaling point code (SPC). The [...]
SS7 also known as Common Channel Signaling System 7 (CCS7) that uses channels separate from the communications channels for signaling and control purposes. SS7 significantly speeds call setup and call completion processes, allows access to databases that enable toll-free calling and number portability, and supports the CLASS (Customer Local Access Signaling Services) services such as [...]
