Example of object code is a NIB file. Contrast with source code. OCC === Other Common Carrier. (Not Bell Telephone.) OCL === Optically Coupled Link. A high-speed coaxial-cable based communications line with a distance limitation of approximately 1,000 feet. octal ===== A numbering system using 8 digits (0, 1, 2, 3, 4, 5, 6, 7). octet ===== The CCITT X.409 term for byte. OEM === Original Equipment Manufacturer. A manufacturer of equipment that may be marketed by another manufacturer. off-line ======== A piece of equipment or a device not in direct communication with the CPU. OM == Operations Manager. A program operators can use to monitor and dynamically change the status of network software products. Provides status information about throughput; port, line, and node management; errors; and statistical performance analysis. on-line ======= A piece of equipment or a device in direct communication with the CPU. on-line reconfiguration ======================= An ISIS-68K function that allows a new SYSCON file to reconfigure a GP board; occurs without disrupting the running of other unaffected GPs in the Turbo Engine chassis. ONA === Open Network Architecture. OnTyme ====== A BT North America enhanced service that provides the user an electronic mail system to send and receive messages through computer terminals. OPCODE ====== Operation Code. Machine language instructions and commands. Open Systems Interconnection (OSI) ================================== A key element in datacommunication is the International Standards Organization (ISO) model for Open Systems Interconnection (OSI). This is a model for modular construction of software for datacommunication and serves as a functional guideline for universal intercomputer communication. It was developed in the late 1970s and formally adopted as an international standard in the spring of 1983. This model is known as CCITT X.200 or ISO 7498. It is composed of seven layers: Physical, Datalink, Network, Transport, Session, Presentation, and Application. Contrast with Systems Architecture Network (SNA). operand ======= Data upon which an operation is performed. For example, in the expression 1 + 2, 1 and 2 are operands. operating system ================ System software that controls the overall operation of a computer system. Operations Manager ================== A program operators can use to monitor and dynamically change the status of network software products. Provides status information about throughput; port, line, and node management; errors; and statistical performance analysis. operator log ============ That part of the NETVAL program that records all network user logins and logouts, as well as NETVAL events such as error conditions. Optically Coupled Link (OCL) ============================ A high-speed coaxial-cable based communications line with a distance limitation of approximately 1,000 feet. option ====== Any macro, EQ statement, or Configuration file parameter that invokes an optional feature available in the code. Can also refer to command line options under UNIX. Optional User Facility ====================== An element within a service that enhances the service. (The element is not one of the basic components of the user service.) Orange Ball =========== A message that is sent in response to the receipt of a Yellow Ball notifying the originator that the data has been received. Also called ISIS Dispatcher message type AD. Original Equipment Manufacturer (OEM) ===================================== A manufacturer of equipment that may be marketed by another manufacturer. origination address =================== The address that originates a circuit or message. Origination and Destination tables ================================== A database found on each Supervisor's disk that contains lists of origination hosts and nodes and destination hosts in a TYMNET network. At login, the Supervisor reads from this database to validate the user's circuit request. The NETVAL program manages this database and forwards this information to each Supervisor. Also called Class (origination) and Group (destination) tables. origination host ================ An address on an origination node from which a circuit is built for a BT North America user session. Contrast with destination host. origination list ================ A list of allowable origination items (node, host, name, class). origination node ================ A node in the network from which a successful login was made and a virtual circuit built. This node usually serves as a terminal interface (TIF). Contrast with destination node. origination port ================ Specifies which port number on the node is sending the data. Contrast with destination port, which is the receiving port. ORING ===== Output Ring. A circular buffer in the slot containing outgoing Dispatcher messages. Used for communication between the Dispatcher and slots. Contrast with Input Ring (IRING). OSE === Open Systems Environment. OSI === Open Systems Interconnection. A key element in datacommunication is the International Standards Organization (ISO) model for Open Systems Interconnection (OSI). This is a model for modular construction of software for datacommunication and serves as a functional guideline for universal intercomputer communication. It was developed in the late 1970s and formally adopted as an international standard in the spring 1983. This model is known as CCITT X.200 or ISO 7498. It is composed of seven layers: Physical, Datalink, Network, Transport, Session, Presentation, and Application. Contrast with Systems Architecture Network (SNA). OTC === Overseas Telecommunication Commission. Other codes =========== see Object code. Out List ======== A list containing information regarding the status of outgoing OnTyme messages, read or unread. Contrast with In List. OutDial ======= Public Asynchronous OutDial or Private Asynchronous OutDial. A BT North America enhanced service that allows the user to communicate with remote asynchronous computers and terminals that are not subscribers to the TYMNET network, over publicly available ports. OutDial can be used to send information from a central computer to remote asynchronous devices, from a PC to another PC, or from a terminal or PC to an asynchronous computer. Output Ring (ORING) =================== A circular buffer in the slot containing outgoing Dispatcher messages. Used for communication between the Dispatcher and slots. Contrast with Input Ring (IRING). output sector ============= Window. An area of memory in Node Code where packets are temporarily stored as they are received from a link. Also called input sector or output sector. overhead ======== Computer time used to keep track of or run the system as compared with computer time used to process data. Also, Control information, in the form of bits, that is added to and transmitted with data. overhead bit ============ A bit such as a check bit or framing bit that is added to the data as part of the management of the packet. |-|-|-|-|-|-|=|=|=|=|=|=|=|=|=|=|=|-|-|-|-|-|-|-|-|-|-|-|=|=|=|=|=|=| Disclaimer ~~~~~~~~~~ This publication is for informational purposes ONLY.
