One typically shorter patch cable will plug into the front side, whereas the back holds the connection of a much longer and more permanent cable. The assembly of hardware is arranged so that a number of circuits, usually of the same or similar type, appear on jacks for monitoring, interconnecting, and testing circuits in a convenient, flexible manner. 2A remote broadcast trailer's jackfieldPatch panels offer the convenience of allowing technicians to quickly change the path of select signals, without the expense of dedicated switching equipment. This was first used by early telephone exchanges, where the telephone switchboard (a massive array of patch panels) and a large room full of telephone operators running it was ubiquitous.3Patch bays may be half-normal or full-normal, "normal" indicating that the top and bottom jacks are wired together internally. When a patch bay has half-normal wiring, its switching contacts flow through the bottom jacks of the bottom row while connected to the top row; plugging into the output connection will split the signal. If a patch bay is wired to full-normal, then it includes switching contacts in both rows of jacks.4Dedicated switching equipment can be an alternative to patch bays in some applications. Switchers can make routing as easy as pushing a button, and can provide other benefits over patch bays, including routing a signal to any number of destinations simultaneously. However, switching equipment that can emulate the capabilities of a given patch bay is much more expensive.Example: a 16-point S-Video patch panel, with 8 patch cables, may cost $300.00, and connect 8 inputs and 8 outputs. An S-Video matrix routing switcher with the same capability (8x8) would probably cost between $2,000.00 and $4,000.00 new, though it would probably have more capabilities, including audio-follow-video and built-in distribution amplifiers.There are various types of switchers for audio and video, from simple selector switches to sophisticated production switchers. However, emulating or exceeding the capabilities of audio and/or video patch bays requires specialized devices like routing switchers and matrix routers (aka "crosspoint switchers").Like patch panels, switching equipment for nearly any type of signal is available, including analog and digital video and audio, as well as RF (cable TV), MIDI, telephone, networking, electrical, and just about anything else.Switching equipment may be electronic, mechanical, or electro-mechanical. Some switcher hardware can be controlled via computer and/or other external devices. Some have automated and/or pre-programmed operational capabilities. There are also software switcher applications used to route signals and control data within a "pure digital" computer environment.Distribution frames are cheaper, but less convenient.
