Common Channel ignaling ystem No. SS7 is a global standard for telecommunications defined by the International Telecommunication Union (ITU) Telecommunication Standardization Sector (ITU-T). The standard defines the procedures and protocol by which network elements in the public switched telephone network (PSTN) exchange information over a digital signaling network to effect wireless (cellular) and wireline call setup, routing and control. Performance Technologies' SS7 Tutorial
The PSTN standard for signaling that is used for transmitting information alongside the voice conversation of a phone call.
A sophisticated telecommunications protocol that provides out-of-band signaling and a data interface between phone company switches for the express purpose of reducing congestion in the PSTN (Public Switched Telephone Network). For example, without SS7, a long distance call is routed through the network to the called party to make their phone ring or before a busy signal can be returned, thereby tying up circuits along the entire path. With SS7, once the call is dialed, the data interface sends a message to the end switch to ring the phone or to check if the called party is busy before the call is routed. If the call is answered, it is then immediately routed though the network, thereby not using the circuits while the phone is ringing or in busy and no-answer situations.
Signaling System 7. A digital data network carrying signaling information that interfaces with the telephone company voice/data network for services using the American National Standards Institute (ANSI) Common Channel Signaling (CCS7) protocol. Also known as CCS/SS7.
Standard CCS system used with B–ISDN and ISDN. Developed by Bellcore. CCS (Common Channel Signaling) is a signaling system used in telephone networks that separates signaling information from user data. A specified channel is exclusively designated to carry signaling information for all other channels in the system.

Signaling System 7 is an international high speed signaling backbone for the public switched telephone network.
The signaling protocol, Version 7, of the CCS network, based upon American National Standards Institute (ANSI) standards, which allows all carriers' networks to work together. Protocols are: CCS is common channel signaling, which allows signals to be sent in both directions, which results in faster speeds.

Signaling system 7. A signaling system, based on standards set by the International Telecommunications Union, for the transfer of messages between entities in telecommunications networks that enables the setting up, routing and clearing of calls and the transfer of other relevant information relating to the operation of these networks. Signaling System 7 is used for the transfer of such messages between different networks as well as within individual networks.
Signaling System Number 7 (See CCS7). International standard protocol defined for open signaling in the digital public switched network. It is based on a 64 kbps channel and allows for information transfer for call control, database and billing management, and for maintenance functions.
Signaling System 7. Sophisticated network signaling system that utilizes out-of-band signaling where signaling information is sent over a separate channel than the call itself; improves call processing set-up times and frees circuits for voice, data and video transmissions.
A transmission system based on the use of a dumb switch and a smart database. By using this database and switch combination, the number of network features is significantly increased. Another advantage of SS7 is that networks can be easily customized because more knowledge can be contained in the database than can be embedded cost effectively in hardware.
Signaling System 7. Packet switching network protocol used between intelligent nodes in the PSTN to provide signaling to establish and disconnect calls (and other related services including 800 number translation caller ID store and forward ring back concurrent data etc.).
Common Channel Signaling System No. 7 (also called "C7")
Signaling System 7. Standard signaling system used in the PSTN. Developed by Bellcore.
Signaling System 7 is the international data network and signaling protocols that control the PSTN voice circuits and calls. These protocols have country-by-country variations. ITU SS7 is the base on which the national variants are based. ANSI SS7 is the North American SS7 variant.
A signaling method separate from the voice or data channel that letâ€(tm)s intelligent network elements exchange information among themselves.
A specific network control system made up of protocols for the interpretation and use of an array of network control and operation signals. The system puts the information required to set up and manage telephone calls in a separate network rather than within the same network on which the telephone call is made.
The signaling system number 7 (SS7) protocol is used in the public networks to establish connections between switches. ISDN connections to switches that support SS7 have access to true 64 K bit connections between public switches. ISDN connections to switches that do not support SS7 (such as those in the Pacific Bell region) are limited to 56 kbps on each B channel as the switch signaling must be accommodated in-band.
Signaling System 7. The protocol used in the public switched telephone system (the "intelligent network" or "advanced intelligent network") for setting up calls and providing services. SS7 is a separate signaling network that is used in Class 4 and Class 5 voice switches.
Signaling System 7 (Sistema de señalización #7) 6N alización by common channel is a protocol used in networks you publish to establish connections between switches. Conecciones ISDN to switches that they support SS7 has access to 64 connections of Kbps between public conmutadoras power stations.
Signaling System 7 An addressing protocol that speeds up call processing by operating out of band. Includes fraud detection, caller ID, store and forward, ring back, concurrent data, etc.
Signaling System 7. The most efficient signaling method available, SS7 uses a single channel to carry signals for multiple circuits.
Signaling System#7. This signaling system is gradually replacing older systems globally.

Signaling Systems 7. An out-of-band signaling system used to provide basic routing information, call set-up and other call termination functions. Signaling is removed from the voice channel and put on a separate data network.
Signaling System #7. A set of telephony signaling protocols used for call set up and services.
Signaling System 7. The protocol used in public-switched telephone systems for establishing calls and providing services such as 800 numbers, call forwarding, caller ID and number portability.
ignaling ystem; an out-of-band signaling system that provides fast call setup (using circuit-switched connections) and transaction capabilities for remote database interactions.
Signaling System 7. The current international signaling standard for all digital exchanges with integrated services. The SS7 network allows call control and transaction messages from the integrated voice and data network to be transferred on communications paths that are separate from the voice and data connections. It delivers out-of-band signaling that provides fast call setup by means of high-speed, circuit-switched connections and transaction capabilities which deal with remote database interactions. SS7 also plays an integral role in the deployment of ISDN. The SS7 protocol consists of four basic sub-protocols: Message Transfer Protocol (MTP) - Provides functions for basic routing of signaling messages between signaling points. Signaling Connection Control Part (SCCP) - Provides additional routing and management functions for transfer of messages other than call setup between signaling points. Integrated Services Digital Network User Part (ISUP) - Provides for transfer of call setup signaling information between signaling points. Transaction Capabilities Application Part (TCAP) - Provides for transfer of non-circuit related information between signaling points.
