INAP
INAP stands for Intelligent Network Application Protocol or Intelligent Network Application Part. It is the signalling protocol used in Intelligent Networking (IN). It is part of the Signalling System No. 7 (SS7) protocol suite, typically layered on top of the Transaction Capabilities Application Part (TCAP). It can also be termed as logic for controlling telecommunication services migrated from traditional switching points to computer based service independent platform. Applications The International Telecommunication Union (ITU) defines several "capability levels" for this protocol, starting with Capability Set 1 (CS-1).{{cite web , url=https://www.informit.com/library/content.aspx?b=Signaling_System_No_7&seqNum=107 , title=Signaling System No. 7 | Intelligent Network Application Protocol (INAP) , publisher=InformIT , date=2008-07-18 , accessdate=2014-02-26 , archive-url=https://web.archive.org/web/20140304220101/https://www.informit.com/library/content.aspx?b=Signalin ...

NASDAQ
The Nasdaq Stock Market () (National Association of Securities Dealers Automated Quotations Stock Market) is an American stock exchange based in New York City. It is the most active stock trading venue in the US by volume, and ranked second on the list of stock exchanges by market capitalization of shares traded, behind the New York Stock Exchange. The exchange platform is owned by Nasdaq, Inc., which also owns the Nasdaq Nordic stock market network and several U.S.-based stock and options exchanges. History 1971–2000 "Nasdaq" was initially an acronym for the National Association of Securities Dealers Automated Quotations. It was founded in 1971 by the National Association of Securities Dealers (NASD), now known as the Financial Industry Regulatory Authority (FINRA). On February 8, 1971, the Nasdaq stock market began operations as the world's first electronic stock market. At first, it was merely a "quotation system" and did not provide a way to perform electronic tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ticker Symbol
A ticker symbol or stock symbol is an abbreviation used to uniquely identify publicly traded shares of a particular stock on a particular stock market. In short, ticker symbols are arrangements of symbols or characters (generally Latin letters or digits) representing specific assets or securities listed on a stock exchange or traded publicly. A stock symbol may consist of letters, numbers, or a combination of both. "Ticker symbol" refers to the symbols that were printed on the ticker tape of a ticker tape machine. Interpreting the symbol Stock symbols are unique identifiers assigned to each security traded on a particular market. A stock symbol can consist of letters, numbers, or a combination of both, and is a way to uniquely identify that stock. The symbols were kept as short as possible to reduce the number of characters that had to be printed on the ticker tape, and to make it easy to recognize by traders and investors. The allocation of symbols and formatting conventions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intelligent Network
The Intelligent Network (IN) is the standard network architecture specified in the ITU-T Q.1200 series recommendations. It is intended for fixed as well as mobile telecom networks. It allows operators to differentiate themselves by providing value-added services in addition to the standard telecom services such as PSTN, ISDN on fixed networks, and GSM services on mobile phones or other mobile devices. The intelligence is provided by network nodes on the service layer, distinct from the switching layer of the core network, as opposed to solutions based on intelligence in the core switches or equipment. The IN nodes are typically owned by telecommunications service providers such as a telephone company or mobile phone operator. IN is supported by the Signaling System #7 (SS7) protocol between network switching centers and other network nodes owned by network operators. Examples of IN services * Televoting * Call screening * Local number portability * Toll-free ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signalling System No
In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The '' IEEE Transactions on Signal Processing'' includes audio, video, speech, image, sonar, and radar as examples of signal. A signal may also be defined as observable change in a quantity over space or time (a time series), even if it does not carry information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability of animals to communicate with each other by developing ways of signaling. In human engineering, signals are ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transaction Capabilities Application Part
Transaction Capabilities Application Part, from ITU-T recommendations Q.771-Q.775 or ANSI T1.114 is a protocol for Signalling System 7 networks. Its primary purpose is to facilitate multiple concurrent dialogs between the same sub-systems on the same machines, using Transaction IDs to differentiate these, similar to the way TCP ports facilitate multiplexing connections between the same IP addresses on the Internet. TCAP uses ASN.1 BER encoding, as well as the protocols it encapsulates, namely MAP in mobile phone networks or INAP in Intelligent Networks. Overview TCAP messages are sent over the wire between machines. TCAP primitives are sent between the application and the local TCAP stack. All TCAP messages are primitives but there are primitives that are not messages. In other words, some are only transferred inside the local machine. A TCAP primitive is made up of one or more TCAP components. An ITU-T TCAP primitive may be one of the following types: A Begin primitive has ...

International Telecommunication Union
The International Telecommunication Union is a specialized agency of the United Nations responsible for many matters related to information and communication technologies. It was established on 17 May 1865 as the International Telegraph Union, making it the oldest UN agency. The ITU was initially aimed at helping connect telegraphic networks between countries, with its mandate consistently broadening with the advent of new communications technologies; it adopted its current name in 1932 to reflect its expanded responsibilities over radio and the telephone. On 15 November 1947, the ITU entered into an agreement with the newly created United Nations to become a specialized agency within the UN system, which formally entered into force on 1 January 1949. The ITU promotes the shared global use of the radio spectrum, facilitates international cooperation in assigning satellite orbits, assists in developing and coordinating worldwide technical standards, and works to improve ...

Service Switching Point
In telephony, a service switching point (SSP) is the telephone exchange that initially responds, when a telephone caller dials a number, by sending a query to a central database called a service control point (SCP) so that the call can be handled. The service switching point uses the Signalling System No. 7 (SS7) protocols which are responsible for the call setup, management, and termination with other service switching points. Relationship between SSP and SCP With the introduction of the Intelligent Network architecture, service functionality (e.g. UK translation of 0800 non-geographic telephone numbers) is being removed from the actual telephone exchange and devolved out into other computer nodes. In this new architecture, the telephone exchange is known as an SSP and the node that contains the services (and hence ''controls'' the progression of a call) is known as service control point (SCP). Example of a 0800 number translation service In the UK 08XXX numbers are non-geogr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Initial Detection Point (telephony)
The IDP receives a message (IDP Message) initiated by the SSP (service switching point) and transmitted to the service control point SCP via the INAP protocol. The Service Switching Point (SSP) receives a message ''(ISUP Message)'' initiated by the Calling Party, this could be an IAM (Initial Address Message). The SSP evaluates the nature of the message, in the case of the IAM the called and calling party numbers. From this it determines whether it can route the call or whether it needs further instructions. In this case if the SSP does require further instructions it sends an IDP to a service control point SCP SCP may refer to: Organizations Political parties * Soviet Communist Party, the leading political party in the former Soviet Union * Syrian Communist Party * Sudanese Communist Party * Scottish Christian Party Companies * Seattle Computer Produ ... via an IN protocol.

Abstract Syntax Notation One
Abstract Syntax Notation One (ASN.1) is a standard interface description language for defining data structures that can be serialized and deserialized in a cross-platform way. It is broadly used in telecommunications and computer networking, and especially in cryptography. Protocol developers define data structures in ASN.1 modules, which are generally a section of a broader standards document written in the ASN.1 language. The advantage is that the ASN.1 description of the data encoding is independent of a particular computer or programming language. Because ASN.1 is both human-readable and machine-readable, an ASN.1 compiler can compile modules into libraries of code, codecs, that decode or encode the data structures. Some ASN.1 compilers can produce code to encode or decode several encodings, e.g. packed, BER or XML. ASN.1 is a joint standard of the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) in ITU-T Study Group 17 and ISO/ IEC, o ...

Customised Applications For Mobile Networks Enhanced Logic
Customized Applications for Mobile networks Enhanced Logic (CAMEL) is a set of standards designed to work on either a GSM core network or the Universal Mobile Telecommunications System (UMTS) network. The framework provides tools for operators to define additional features for standard GSM services/UMTS services. The CAMEL architecture is based on the Intelligent Network (IN) standards, and uses the CAP protocol. The protocols are codified in a series of ETSI Technical Specifications. Many services can be created using CAMEL, and it is particularly effective in allowing these services to be offered when a subscriber is roaming, like, for instance, No-prefix dialing (the number the user dials is the same no matter the country where the call is placed) or seamless MMS message access from abroad.
