Stimulus Protocol
In telephony, a stimulus protocol is a type of protocol that is used to carry event notifications between end points. Such a protocol is used to control the operation of devices at each end of the link. However a stimulus protocol is not sensitive to the system state. In a typical application such a protocol will carry keystroke information from a telephone set to a central call control. It may also carry control information for simple types of text displays. MiNET from Mitel is a typical protocol of this sort. Stimulus protocols are most suited to networks with dumb peripherals and intelligent centralized applications (see intelligent network). This is in contrast to functional protocols which are best suited to a network with an intelligent periphery and a dumb core (see dumb network). Because these architectures share core hardware over large numbers of peripherals, large and expensive computing capabilities in terms of both hardware and software may be supplied. These centrali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephony
Telephony ( ) is the field of technology involving the development, application, and deployment of telecommunications services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone. Telephony is commonly referred to as the construction or operation of telephones and telephonic systems and as a system of telecommunications in which telephonic equipment is employed in the transmission of speech or other sound between points, with or without the use of wires. The term is also used frequently to refer to computer hardware, software, and computer network systems, that perform functions traditionally performed by telephone equipment. In this context the technology is specifically referred to as Internet telephony, or voice over Internet Protocol (VoIP). Overview The first telephones were connected directly in pairs: each user had a separate telephone wire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Call Control
In telephony, call control refers to the software within a telephone switch that supplies its central function. Call control decodes addressing information and routes telephone calls from one end point to another. It also creates the features that can be used to adapt standard switch operation to the needs of users. These are called supplementary services and are commonly invoked by a Vertical service code. Examples include " Call waiting", " Call forward on busy" etc. Call control software, because of its central place in the operation of the telephone network, is marked by both complexity and reliability. Call control systems will typically require many thousands of person years in development. They will contain millions of lines of high level code. However they must and do meet reliability requirements that specify switch down time of only a few minutes in forty years. The required functionality and reliability of call control is a major challenge for Voice over IP (VoIP) system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mitel
Mitel Networks Corporation is a Canadian telecommunications company. The company previously produced TDM PBX systems and applications, but after a change in ownership in 2001, now focuses almost entirely on Voice-over-IP (VoIP), unified communications, collaboration and contact center products. Mitel is headquartered in Ottawa, Ontario, Canada, with offices, partners and resellers worldwide. In April 2018, the company announced it had been bought by an investor group led by Searchlight Capital Partners. History Founding Michael Cowpland and Terry Matthews founded Mitel in 1973 (officially on June 8, 1973). Conventionally, its name is regarded as a combination of the founders’ first names and their first product, ''Mike and Terry Lawnmowers.'' Michael Cowpland stated that the name stands for ''Mike and Terry Lawnmowers'', whereas Terry Matthews confirmed the lawnmower acronym during an interview on BBC Radio 4's ''The Bottom Line'' in May 2011.

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 cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dumb Network
A dumb pipe or dumb network, in relation to a mobile network operator (MNO), is a simple network that has high enough bandwidth to transfer bytes between the customer's device and the Internet without the need to prioritize content. This means it can afford to be completely neutral with regard to the services and applications the customer accesses. This is in contrast to a smart pipe where the operator affects the customer's accessibility of the Internet by either limiting the available services or applications to its own proprietary portal (like a walled garden) or offer additional capabilities and services beyond simple connectivity. A dumb pipe primarily provides simple bandwidth and network capacity which is greater than the maximum network loads expected thus avoiding the need to discriminate between packet types. Among the commonly understood operational models for an MNO are dumb pipes, smart pipes, and the walled gardens. Description A dumb network is marked by using ...

Session Initiation Protocol
The Session Initiation Protocol (SIP) is a signaling protocol used for initiating, maintaining, and terminating communication sessions that include voice, video and messaging applications. SIP is used in Internet telephony, in private IP telephone systems, as well as mobile phone calling over LTE (telecommunication), LTE (VoLTE). The protocol defines the specific format of messages exchanged and the sequence of communications for cooperation of the participants. SIP is a text-based protocol, incorporating many elements of the Hypertext Transfer Protocol (HTTP) and the Simple Mail Transfer Protocol (SMTP). A call established with SIP may consist of multiple media streams, but no separate streams are required for applications, such as text messaging, that exchange data as payload in the SIP message. SIP works in conjunction with several other protocols that specify and carry the session media. Most commonly, media type and parameter negotiation and media setup are performed with t ...

IETF
The Internet Engineering Task Force (IETF) is a standards organization for the Internet standard, Internet and is responsible for the technical standards that make up the Internet protocol suite (TCP/IP). It has no formal membership roster or requirements and all its participants are volunteers. Their work is usually funded by employers or other sponsors. The IETF was initially supported by the federal government of the United States but since 1993 has operated under the auspices of the Internet Society, a non-profit organization with local chapters around the world. Organization There is no membership in the IETF. Anyone can participate by signing up to a working group mailing list, or registering for an IETF meeting. The IETF operates in a bottom-up task creation mode, largely driven by working groups. Each working group normally has appointed two co-chairs (occasionally three); a charter that describes its focus; and what it is expected to produce, and when. It is open ...

Network Protocols
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any variation of a physical quantity. The protocol defines the rules, syntax, semantics, and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses predetermined for that particular situation. The specified behavior is typically independent of how it is to be implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there is a close analogy between protocols and programming languages: ''protocols are to communicat ...
