An SS7 point code is an address for the SS7 telephone switching system. It is similar to an IP address in an IP network. It is a unique address for a node (Signaling Point, or SP), used in MTP layer 3 to identify the destination of a message signal unit (MSU).
Signalling System No. 7 (SS7) ... a signaling point code. Extended services are provided by a database interface at the SCP level using the SS7 network.
Circuit Identification Code; Message Type; Mandatory Fixed Part; Mandatory Variable Part; Optional Part; The Routing Label indicates the Point Codes of the originating and destination nodes in the network; it also includes the Signalling Link Selection field that is used to select between the multiple routes an MSU could take between two nodes.
A Signal Transfer Point (STP) is a node in an SS7 network that routes signaling messages based on their destination point code in the SS7 network. [1] It works as a router that relays SS7 messages between signaling end-points (SEPs) and other signaling transfer points (STPs).
MTP3 provides routing functionality to transport signaling messages through the SS7 network to the requested endpoint. Each network element in the SS7 network has a unique address, the Point Code (PC). Message routing is performed according to this address.
The type of number (TON) or Nature of Address Indicator (NAI) parameter, which is of relevance to E.164 (regular telephone) numbers for example, indicates the scope of the address value, such as whether it is an international number (i.e. including the country code), a "national" or domestic number (i.e. without country code), and other formats such as "local" format (e.g. in the U.S., without ...
The SSP is responsible for sending call information to the service control point (SCP), routing the request through at least one signal transfer point (STP) in the Signalling System 7 (SS7) network. SS7 is a digital out-of-band method of transmitting signalling (call control) information in the Public Switched Telephone Network (PSTN).
A Point Code is used to address a particular node on the network, whereas a Subsystem number addresses a specific application available on that node. SCCP employs a process called Global Title Translation to determine Point Codes from Global Titles so as to instruct MTP on where to route messages.
