The person who can use root, the most privileged account. The administrator must have a personal login account for daily use, but, when there are serious system problems to correct, he or she logs in to the root account to change system information using the graphical tools or using the IRIX shell.
The administrator has all the capabilities of a privileged user, plus the capability to change information in the root account (such as the password) and to log in to an IRIX shell as root. Because there is only one root account, there is only one administrator per system. The Information Panel for a particular system includes the name of the system's administrator so that other users know who to contact for help.
An ISDN service that includes two B channels and one D channel.
Two separate conduits across which ISDN transfers data on your workstation. Each B channel is capable of transferring up to 64 Kbits/second. D channel.
A test to ensure that a particular device (such as the keyboard, mouse, or ISDN) is set up and working properly.
A term that the telephone company uses to describe the end-user equipment needed to make an ISDN connection.
A single conduit across which ISDN on your workstation transfers signalling and protocol data (but no user data). The D channel can transfer up to 16 Kbits/second. See also B channels.
A unque name that identifies each host (system) on the network.
A short version of a hostname. For UUCP applications, it must be seven characters or less.
The hostname of a system through which all ISDN connections to a particular network are made.
A combination of software, hardware, and telephone services that lets you communicate with other systems and networks over a high-speed telephone line just as you communicate with other systems and networks over an Ethernet cable.
The person or agency that administers the system or network to which you connect via ISDN.
The unique number that identifies each system on the network.
See Integrated Services Digital Network.
Information about a person who can log in to the system, including the person's full name, login name, contact information, and the name of a home directory in which the person can store directories and files.
A short version of your own name or your initials; you type it to log in to the system, and the system uses it to label files that belong to you. If your system is on a network, the network administrator usually must approve of the name to make sure it is unique.
A small external hardware device (often the size of a standard VHS videotape) that converts the standard 2- or 4-wire telephone jack signal (the U interface) to an 8-wire ISDN signal (the S/T interface). Some NT1 units may need a companion power supply unit.
A combination of letters and/or numbers that only you know; it is an optional element of your login account. If you specify a password for your account, you must type it after you type your login name for the system to let you access files and directories.
The information attached to each directory and file that specifies which users can access it and to what degree.
A connection made using the PPP protocol and ISDN hardware and software where there is more than one device (e.g., a telephone and a workstation) on one end of the connection and a single device (e.g., a server located at an Internet service provider's offices) at the other end.
A connection that uses the PPP protocol and ISDN hardware and software with one device (point) on each end of the phycical connection. See also point-to-multipoint.
a standard communications protocol for transmitting network data over point-to-point links using modems or ISDN lines. You can use it to transfer data between systems that use TCP/IP or UDP/IP.
See Point-to-Point Protocol.
See Primary Rate Interface (PRI).
An ISDN service that requires a T1 link or PBX line; it is used for high-end video teleconferencing or for a large volume of outbound calls. It will not work over a standard telephone line; some workstations cannot use PRI. See also Basic Rate Interface (BRI).
A character or word that the system displays in an IRIX shell to indicates that the system is ready to accept commands. The default prompt for regular user accounts is %; the default prompt for the root account is #.
The standard, 4-wire cable that you use to plug a telephone into a standard wall jack. In an ISDN connection, it connects the NT1 device or power supply unit to the wall jack.
A high-speed 8-wire cable that looks similar to the RJ-11 (standard telephone cable) but has larger connectors. In an ISDN connection, it connects the NT1 device to the ISDN port on the workstation. If you have a companion power supply for the NT1 device, use a second, shorter RJ-45 cable to connect the NT1 device to the power supply unit.
The standard IRIX login account reserved for use by the system administrator. This account's home directory is the root (/) directory of the filesystem; the user of the root account has full access to the entire filesystem (that is, can change and delete any file or directory). The user of this account is sometimes referred to as the superuser.
A continuously running program that determines the network route by which data will be transferred. gated and routed are the two standard routing daemons available on your system.
Standard system software that lets you connect to a network using a serial cable and a modem rather than an Ethernet cable. Once you're connected, you can use the network as if you were connected by an Ethernet cable.
See Serial Line Internet Protocol (SLIP).
A number that typically consists of 11 to13 digits. For each ISDN telephone number, the telephone company assigns a corresponding SPID number. You need to know your two SPID numbers for these switch software types: 5ESS National ISDN 1; DMS100 BCS level 31, 32, 33, or 34 (Protocol Version 1); DMS BCS level 35 or higher (Protocol Version 2).
See Service Profile Identifier (SPID).
The 8-wire high-speed port used to transfer data using ISDN. The NT1 device's S/T interface port is usually labeled S/T; the S/T interface port on the workstation (the ISDN port) is labeled with a telephone icon. These ports accept an RJ-45 cable.
A portion of a software product. Each product consists of several subsystems; some are requred and some are optional.
An alternate name for the user of the root login account. See also system administrator.
The large computer located in the telephone company's central switching office through which telephone calls are routed. In the United States, the two types of switch hardware are 5ESS and DMS100. See also switch software.
The type of software that runs on the switch hardware. In the United States, switch software types include 5ESS Custom, 5ESS NI1, DMS100 BCS level 31, 32, 33, or 34 (Protocol Version 1), and DMS100 BCS level 35 or higher (Protocol Version 2); the last type is also sometimes called DMS NI1. In Germany, switch software types include 1TR6 or NET3 (also known as Euro-ISDN or DSS-1). The rest of Europe has NET3 switch software, and Japan has NTT.
The toolchest in the upper-left portion of the screen from which you can access all system administration tools.
See Terminal Adapter (TA).
The standard networking software that's included in the system software.
Technically, a device that allows terminals to access ISDN through serial lines. It has become a generic term for ISDN end-user equipment. For example, the telephone company may refer to the workstation as a TA.
The standard, 2- or 4- wire wall jack port for a telephone. It accepts an RJ-11 cable.
Standard system software that lets you connect to a network using a serial cable and a modem rather than an Ethernet cable. Once you're connected, you can log into a single system through one window; your system essentially behaves like a dumb terminal.
