Basic Concept Signalling System No. 7 - Signalling Point

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 SP generating signaling messages is called the originating signaling point (OPC), and the SP to which the signaling messages are sent is called the destination signaling point (DPC).
DSPĀ  is any SP visible to the OPC in the entire signaling networks where the OPC is located. The DSP with direct signaling link is called adjacent DSP, while the DSP without direct signaling link is called non-adjacent DSP.

Basic Concept Signalling System No. 7

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 caller ID, name ID, selective ringing (or priority ringing), selective call forwarding, call block (or call screen), repeat dial, call trace, and automatic call-back (call return).
It is optimized for use in digital telecommunication networks and designed to meet present and future information transfer requirements to provide reliable means for the transfer of information.
Here I try to discuss about elements of SS7 : Signalling Network, Signalling Point, Signaling Link, signaling Linkset and Signaling Route, and SS7 Transfer Mode.
