Each outlet is then patched into a network switch (normally also rack-mounted) for network use or into an IP or PBX (private branch exchange) telephone system patch panel. Lines patched as data ports into a network switch require simple straight-through patch cables at each end to connect a computer.
A patch panel is a device or unit featuring a number of jacks, usually of the same or similar type, for the use of connecting and routing circuits for monitoring, interconnecting, and testing circuits in a convenient, flexible manner. Patch panels are commonly used in computer networking, recording studios, and radio and television.
Punch-down blocks are a very quick and easy way to connect wiring, as there is no stripping of insulation and no screws to loosen and tighten. Punch-down blocks are often used as patch panels, or as breakout boxes for PBX or other similar multi-line telephone systems with 50-pin RJ21 connectors. [2]
Breakout boxes (also called patch bays or patch panels) are used to patch audio/video output signals from multiple sources and connect them to other devices quickly. These boxes range from simple analog audio interconnects with up to 96 audio ins/outs [ 6 ] to complex plug-in component with composite video, S-Video, HDMI, RS422 control, and ...
A patch cable, patch cord or patch lead is an electrical or fiber-optic cable used to connect ("patch in") one electronic or optical device to another for signal routing. Devices of different types (e.g., a switch connected to a computer, or a switch to a router ) are connected with patch cords.
An Ethernet crossover cable is a crossover cable for Ethernet used to connect computing devices together directly. It is most often used to connect two devices of the same type, e.g. two computers (via their network interface controllers) or two switches to each other.
A 110 punch block. A 110 block is a type of punch-down block used to terminate runs of on-premises wiring in a structured cabling system. The designation 110 is also used to describe a type of insulation displacement contact (IDC) connector used to terminate twisted pair cables, [1] which uses a punch-down tool similar to the type used for the older 66 block.
Having a DCS in a circuit-switched network provides important flexibility that can otherwise only be obtained at higher cost using manual "DSX" cross-connect patch panels. DCS devices "switch" traffic, but they are not packet switches—they switch circuits, not packets, and the circuit arrangements they are used to manage tend to persist over ...
