What structures does the application layer of the No.7 signaling network protocol include?

Signaling monitoring system is divided into two sets: data information monitoring and traffic information monitoring. ...

No.7 signaling network is a signaling network that guides the work of PSTN telephone network, and it is a packet network that is logically independent of PSTN telephone network. It can not only be used to transmit the inter-office signaling needed for the circuit connection between telephone network and integrated services digital network, but also be used for mobile switching center (MSC), visitor location register (VLR) and home location register (HLR) of mobile communication network. ...

What is the basic signaling unit of No.7 signaling and how to distinguish it?

N0.7 signaling has three basic units: message signal unit (MSU), link state signal unit (LSSU) and padding signal unit (FISU).

How many layers does signaling system No.7 have? What floor do Tupou and ISUP belong to?

Signaling system No.7 consists of four layers. TUP and ISUP belong to the fourth functional layer of signaling system No.7, and each layer is defined as follows: (1) Signal link function (first layer): this layer is used for the bidirectional transmission path of signals. It consists of two data paths working in reverse at the same data rate. (2) Link control function (Level 2): This level provides two signaling functions. ...

Working principle of No.7 signaling network

The first chapter briefly describes that in order to meet the needs of telecommunication networks, the basic goal of No.7 signaling mode is to transparently transmit business signaling and other forms of information required by various users (exchange offices) in the form of public channels separated from live channels, so as to meet the needs of special business networks and various business networks. 1, basic term l information n user information: voice, data n ...

Signaling Network No.7 is a multi-level network structure.

China Toll No.7 Signaling Network adopts three-level structure, which is divided into three levels: high-level signaling transfer point (HSTP), low-level signaling transfer point (LSTP) and signaling point (SP). Among them, the local No.7 signaling network in large and medium-sized cities adopts a two-level structure, which consists of (LSTP) and (SP).
