 the local telephone company to the end user's premises. The local loop can use fiber, copper, or wireless media. LTE (Long-Term Evolution) A 4G mobile protocol that uses packet switching to carry voice, data, and multimedia traffic more efficiently than earlier protocols. It will eventually support broadband speeds of up to 100Mbps. LTE was developed by the 3rd Generation Partnership Project. LUN (Logical Unit Number) An identifier in Storage Area Networks (SANs). It identifies the particular database stored in a computer www.TechnicalPDF.com disk. LUNs are part of the Fibre Channel protocol used in SANs. MAN (Metropolitan Area Network) A network that covers a metropolitan area such as a portion of a city. Hospitals, universities, municipalities, and large corporations often have telephone lines running between sites within a city or suburban area. Mbps (millions of bits per second) A transmission speed at the rate of millions of bits in one second. Digital telephone lines measure their capacity or bandwidth in bits per second. media gateways Contain Digital Signal Processors (DSPs) that compress voice traffic to make it smaller SO that it can be carried more efficiently. In addition, media gateways are equipped with circuit packs with ports for connections to traditional circuit-switched analog and T1 trunks. Thus, they are used to link converged IP networks to Public Switched Telephone Networks. media servers Specialized computers that play announcements and generate ring tones in corporate telephone systems and converged public networks. In corporate VoIP systems, they control call processing. media servers for homes (home servers) PCs or separate devices that store content, music, photos, movies, or TV shows that can be distributed over home networks to home entertainment equipment. mesh networks Networks in which every device is connected to every other device. Community wireless networks and sensor networks often use variations of mesh networks, as does the military when it sets up communications facilitie
