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.
A keystone module for a CAT5 network cable A 3-port keystone wall plate. A keystone module is a standardized snap-in package for mounting a variety of low-voltage electrical jacks or optical connectors into a keystone wall plate, face plate, surface-mount box, or a patch panel.
In switch rooms, 110 blocks are often built into the backs of patch panels to terminate cable runs. At the other end, 110 connections may be used with keystone modules that are attached to wall plates. 110 blocks are preferred over 66 blocks in high-speed networks because they introduce less crosstalk and many are certified for use in Category ...
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 ...
The punch-down blocks on patch-panel and wall-port jacks are designed for use with solid core cable. These work via the insulation-displacement method, whereby the device pierces the sides of the insulation and "bites" into the copper conductor to form a connection. Punchdown blocks are used as patch panels or as break-out boxes, for twisted ...
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 ...
It is usual practice to install "fixed cables" between cabling closets or cabinets. These cables are contained in cable trays etc., and are terminated at each end onto patch panels in the communications cabinet or outlets at the desktop. The circuits are then interconnected to the final destination using patch cables.
