Telecom equipment - Vector stencils library

The vector stencils library "Telecom equipment" contains 11 hardware clipart icons of telecommunication devices for drawing computer network diagrams and equipment layouts.
"In telecommunication, a communications system is a collection of individual communications networks, transmission systems, relay stations, tributary stations, and data terminal equipment (DTE) usually capable of interconnection and interoperation to form an integrated whole. The components of a communications system serve a common purpose, are technically compatible, use common procedures, respond to controls, and operate in union. Telecommunications is a method of communication." [Communications system. Wikipedia]
"A basic telecommunication system consists of three primary units that are always present in some form: (1) A transmitter that takes information and converts it to a signal. (2) A transmission medium, also called the "physical channel" that carries the signal. ... (3) A receiver that takes the signal from the channel and converts it back into usable information." [Telecommunication. Wikipedia]
The clip art example "Telecom equipment - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Telecommunication Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

The vector stencils library "Cisco telepresence" contains 8 symbols of videoconference and telepresence equipment: Cisco TelePresence Systems, CTS-codecs primary and secondary, multipoint control unit (MCU), TelePresence MCU (TP MCU), Cisco telepresence manager.
Use it to create the computer network diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"A teleconference or teleseminar is the live exchange and mass articulation of information among several persons and machines remote from one another but linked by a telecommunications system. Terms such as audio conferencing, telephone conferencing and phone conferencing are also sometimes used to refer to teleconferencing.
The telecommunications system may support the teleconference by providing one or more of the following: audio, video, and/ or data services by one or more means, such as telephone, computer, telegraph, teletypewriter, radio, and television." [Teleconference. Wikipedia]
The example "Design elements - Cisco telepresence" is included in the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

"Videoconferencing is the conduct of a videoconference (also known as a video conference or videoteleconference) by a set of telecommunication technologies which allow two or more locations to communicate by simultaneous two-way video and audio transmissions. It has also been called 'visual collaboration' and is a type of groupware. ...
The core technology used in a videoconferencing system is digital compression of audio and video streams in real time. The hardware or software that performs compression is called a codec (coder/ decoder). Compression rates of up to 1:500 can be achieved. The resulting digital stream of 1s and 0s is subdivided into labeled packets, which are then transmitted through a digital network of some kind (usually ISDN or IP). The use of audio modems in the transmission line allow for the use of POTS, or the Plain Old Telephone System, in some low-speed applications, such as videotelephony, because they convert the digital pulses to/ from analog waves in the audio spectrum range.
The other components required for a videoconferencing system include:
(1) Video input : video camera or webcam.
(2) Video output: computer monitor, television or projector.
(3) Audio input: microphones, CD/ DVD player, cassette player, or any other source of PreAmp audio outlet.
(4) Audio output: usually loudspeakers associated with the display device or telephone.
(5) Data transfer: analog or digital telephone network, LAN or Internet.
(6) Computer: a data processing unit that ties together the other components, does the compressing and decompressing, and initiates and maintains the data linkage via the network." [Videoconferencing. Wikipedia]
