`NEWTON'S TELECOM DICTIONARY
`
`Port 1. An entrance to or an exit from a network.
`2, The physical or electrical interface through which one gains access. A point in the computer or telephone system where data
`may be accessed. Peripherals — like call accounting devices — are connected to ports. The two most common ports are the
`parallel and serial ports.
`3. The interface between a process or program and a communications or transmission facility.
`4. To move a process, program or subroutine from one processor to controller to another ('port it over").
`5. Network access paint for data entry or exit. In Internet terms, it is the identifier (16-bit unsigned integer) used by Internet trans-
`port protocols to distinguish among multiple simultaneous connections to a single destination host.
`Pon Connection The point of entry into a public frame relay network service.
`Port Identifier The identifier assigned by a logical node to represent the point of attachment of a link to that node.
`Port Multiplier A local area network interconnect, a concentrator providing connection to a network for multiple devices.
`Port Replicolors Low-cost docking station substitutes that provide one-step connection to multiple desktop devices.
`Port Selector Another name for a dataPBX• Since the advent of LANs (local area networks) these devices have been getting
`a bad rap. Not fair. These gadgets are really great at transmitting and switching huge number of low-speed asynchronous lines.
`If you put this sort of traffic on a LAN, you could severely mess up its performance. Some port selectors have data throughput
`in excess of 20 million hits per second.
`Port Sharing 1. A system which-connects multiple lines to a single port by means of a manual or automatic line selection method.
`2. In frame relay, *here multiple virtual connections share the same port connection.
`Port Shoring Device A system which connects multiple lines to a single part by means of a manual or automatic line selection method.
`Port Switching According to 3Com, port switching is merely an electronic patch panel function, not the genuine switching
`capability that provides a performance boost. Port switching lets administrators configure their networks, allocating any port to
`any backp lane on their hub. Unlike true switching, it doesn't increase the bandwidth available to the network manager.
`Portability 1. The ability of a customer to take his telephone number from place to place and, for 800 numbers, from one
`long-distance company to another.
`2, The ability of software designed for one computer system to be used on other systems. Little software outside MS-DOS soft-
`ware for IBM and IBM clone computers is portable. UNIX software Is portable to an extent.
`Portable A one-piece, self-contained cellular telephone
`easily carried in a brief case or purse. Portables normally have a built-in
`antenna and rechargeable battery and operate with six-tenths of one watt (0.6 watt) of power. Car cellular phones operate with three watts.
`Portable Cellular Phone Also known as a "hand-held phone". Refers to a lightweight, compact cellular handset that incor-
`porates a battery power supply, and can be used without any peripheral power or antenna. See PORTABLE.
`Portable Teletrunsaction Computers PTC. These are typically handheld devices used for retail (inventory), healthcare
`(tracking supplies), mobile field repair (reporting fixes), insurance (visiting car wrecks and other disasters), etc. The devices typ-
`ically have telecommunications capabilities, sometimes wireless, sometimes landlines. And they typically include microproces-
`sors, memories, displays, keyboards, touchscreens, character recognition software, barcode readers, printers, modems and local
`and/or wide area data radios.
`Portrait Most computer screens are horizontal, i.e. they are wider than they are high. In the new language of computer screens,
`this is called "landscape." When a computer screen is higher than it is wide, it's called "portrait." Some computer screens can
`actually work both ways. Some even have a small mercury switch in them that determines which way the screen is standing (por-
`trait or landscape) and will adjust their image accordingly. See also PORTRAIT MODE.
`'-
`Portrait Mode 1. In facsimile, the mode of scanning lines across the shorter dimension of a rectangular original. ITU-T
`Group 1, 2 and 3 facsimile machines use portrait mode.
`2. In computer graphics, the orientation of a page in which the shorter dimension is horizontal. The opposite is called landscape
`mode. See also PORTRAIT.
`POS 1. Point Of Service. Also called Point of Presence. See POINT OF PRESENCE.
`2. POS Device. A point of sale device such as a credit card scanner used for authorization when a purchase is made.
`POSI Promoting Conference for OSI. Consists of executives from the six major Japanese computer manufacturers and Nippon-
`Telephone and Telegraph. They set policies and commit resources to promote OSI.
`--
`Position A telephone console at a switchboard manned, er, staffed by an attendant, or operator, or agent, or whatever the lat-
`est fashionable word is.
`Positive Action Digit A digit that must be dialed before a PBX will advance a call to a higher-cost route. The WATS lines
`are busy. Time on the queue is over. It's time to move the calf to the more expensive direct distance dial. Before it can go that
`route, the caller must punch in a positive action digit. This affirms that the user knows he is now making a more expensive call.
`It causes him to think twice, allegedly.
`POSIX Portable Operating System Interface uniX. A proposed universal UNIX interface to user-created application programs
`that would run on all vendor equipment, thereby improving system interoperability.
`Post 1. To compose a message for an Internet Usenet newsgroup and then send it out for others to see.
`2. Power-On Self-Test
`Post Dili Delay PD D. The time from when the last digit is dialed to the moment the phone rings at the receiving location.
`Post Office Any part of an e-mail system that directors or delivers mail. But, says PC Magazine's David Stone, to refer to a
`particular level of mail handling, the term post office needs a modifier. A local post office or host post office is the module on a
`LAN that users directly interact with to send and receive mail. A domain:post office is the module that controls the mail delivery
`within a domain of multiple hosts on a single network.
`In Windows 95, the postoffice is a temporary message store, holding the message until the recipient's workstation retrieves it.
`The postoffice exists as a directory structure on a server and has no programmatic components.
