  • Fax
    Fax (short for facsimile), sometimes called telecopying or telefax (the latter short for telefacsimile), is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output device.
  • Personal Handy-phone System
    The Personal Handy-phone System (PHS), also marketed as the Personal Access System (PAS) and commercially branded as Xiaolingtong (Chinese: 小灵通) in Mainland China, is a mobile network system operating in the 1880–1930 MHz frequency band, used mainly in Japan, China, Taiwan, and some other Asian countries and regions.
  • Submarine communications cable
    A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean.
  • Telephone
    A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly.
  • Pager
    A pager (also known as a beeper) is a wireless telecommunications device that receives and displays numeric messages and/or receives and announces voice messages.
  • Stepping switch
    In electrical controls, a stepping switch or uniselector (UK), also known as a stepping relay, is an electromechanical device which allows an input connection to be connected to one of a number of possible output connections, under the control of a series of electrical pulses.
  • Terminal server
    A terminal server (also referred to as a serial server or console server network access server) enables organizations to connect devices with an RS-232, RS-422 or RS-485 serial interface to a local area network (LAN).
  • Transceiver
    A transceiver is a device comprising both a transmitter and a receiver that are combined and share common circuitry or a single housing.
  • Circulator
    Ferrite circulators are radio frequency circulators which are composed of magnetised ferrite materials.
  • Digital cross connect system
    A digital cross-connect system (DCS or DXC) is a piece of circuit-switched network equipment, used in telecommunications networks, that allows lower-level TDM bit streams, such as DS0 bit streams, to be rearranged and interconnected among higher-level TDM signals, such as DS1 bit streams.
  • Squelch
    In telecommunications, squelch is a circuit function that acts to suppress the audio (or video) output of a receiver in the absence of a sufficiently strong desired input signal.
  • Utility pole
    A utility pole is a column or post used to support overhead power lines and various other public utilities, such as cable, fibre optic cable, and related equipment such as transformers and street lights.
  • Intercom
    An intercom (intercommunication device), talkback or doorphone is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public telephone network (Azori 2016).
  • Add-drop multiplexer
    An add-drop multiplexer (ADM) is an important element of an optical fiber network.
  • Telex
    The telex network is a switched network of teleprinters similar to a telephone network, for the purposes of sending text-based messages.
  • Microwave antenna
    A microwave antenna is a physical transmission device used to broadcast microwave transmissions between two or more locations.
  • Master clock
    A master clock is a precision clock that provides timing signals to synchronise slave clocks as part of a clock network.
  • Hellschreiber
    The Hellschreiber or Feldhellschreiber (also Hell-Schreiber named after its inventor Rudolf Hell) is a facsimile-based teleprinter invented by Rudolf Hell.
