ABBREVIATION DICTIONARY Networks and Telecommunications/Electronics -->W

W

WAN
Wide Area Network. A data network typically extending a LAN outside a building or beyond a campus, over IXC or LEC lines to link to other LANs at remote sites. Typically created by using bridges or routers to connect geographically separated LANs.







WAN Connection
A connection between two endpoints over a WAN, as opposed to a local connection by a serial or Ethernet link.







WAN Interface
The port on the Lucent unit that is connected to a WAN line.







WAN Port
A T1 or E1 port that provides a point-to-point connection between the Lucent unit and another device.







WCPE
An air-interface standard technology adapted from the Digital European Cordless Telecommunications standard.







WINS
Windows Internet Name Service. Windows Internet Name Service (WINS) is a Microsoft product that manages the mapping between resource names (in the form of easy-to-remember nicknames) and IP addresses. The DNS service used on the Internet cannot map between IP addresses and local resource names dynamically. However, through dynamic database updates, WINS lets users access network resources via more user-friendly names instead of IP addresses.







WSN
Wang Span Network







Wafer
A thin disk of purified crystalline semiconductor, typically silicon, that is divided into chips after processing. See for more info.







Warmboot
A reboot performed while the operating system is running.







Watchdog Request
Used by NetWare Servers to see who is still logged into the server. A NetWare client who is logged on must respond to this request with a "watchdog response" or else the newer server will log the client off. These broadcasts can keep up the line. However, if the line is down and comes up by itself, watchdog requests will not likely be the cause of the problem since we spoof these requests.







Watchdog Spoofing
NetWare servers send "session keep alive" packets to clients who must return the packet to keep a session active. Ascend units can reply to NetWare Core Protocol (NCP) watchdog packets on behalf of clients on the other side of a bridge, causing the server to sense that the link is still active. Effectively imitating a return "session keep alive" packet is called watchdog spoofing.







Wavelength
1. The physical distance between two adjacent peaks or valleys in a wave. 2.The property of light that determines its color.







Wavelength Division Multiplexing (WDM)
Optical transmission technique in which two or more wavelengths (each carrying its own information), are combined for transmission over a single optical fiber. At the receiving end, the wavelengths are separated and directed to separate receivers.







Web
Short for World Wide Web.







WiWebXtend
The Web browser user interface built into Lucent broadband access products.







Wide Area Network
A data network typically extending a LAN outside a building or beyond a campus, over IXC or LEC lines to link to other LANs at remote sites. Typically created by using bridges or routers to connect geographically separated LANs.







Wideband
Digital communication between 1.5 Mbps and 45 Mbps.







Wideband Packet Technology
Packet switched services operating at speeds between 50 Kbps and 500 Mbps.







Wink
On a telephone line, a signal that is comprised of an on-hook/off-hook/on-hook transition.







Wire Bonding
In chip manufacture, a process for connecting the bonding pads on a chip to the lead frame via tiny gold wires. See for more info.







Wireless Communications
Technologies that provide mobile communications for home or office, and "in-building wireless" for extended mobility around the work area, campus, or business complex. It is also used to mean "cellular" for in- or out-of-building mobility services.







Wireless Modem
A modem that uses radio transmission technology to transmit data between remote locations. A wireless modem is often used by mobile clients in locations where access to a landline connection is not feasible.







Wireless Technology
A communications system in which electromagnetic waves carry the signal. Examples of wireless equipment include cellular telephones, pagers, the cordless mouse, and wireless transceivers for connecting to the Internet.







World Wide Web
Also known as the Web. An Internet facility that links documents anywhere in the world. A Web document is called a Web page, and links in the page let users jump from page to page (hypertext), whether the pages are stored on the server located down the hall or on servers around the globe. The pages are accessed and read via a Web browser such as Netscape Navigator or Internet Explorer.







wavelength
The physical distance between two adjacent peaks or valleys in a wave;.the property of light that determines its color.
