A network used for signaling by one or more users and consisting of signaling points and connecting signaling links. [T1.110-1987] [T1.226-1992]

The functions that are performed by the message transfer part at level 3 and are common to, and independent of, the operation of individual signaling links. They include the signaling message handling functions and the signaling network management functions.
Note: The message handling functions include functions for message distribution, message discrimination, and message routing. [T1.110-1987][T1.226-1992]

Functions that control the current message routing and configuration of signaling network facilities based on predetermined data and current information about the status of the signaling network. [T1.226-1992]

The Transmission Control Protocol/Internet Protocol (TCP/IP) standard protocol that (a) is used to manage and control IP gateways and the networks to which they are attached, (b) uses IP directly, bypassing the masking effects of TCP error correction, (c) has direct access to IP datagrams on a network that may be operating abnormally, thus requiring management, (d) defines a set… (Read More →)

A ring network that allows unidirectional data transmission between data stations by transferring data in predefined slots in the transmission stream over one transmission medium such that the data return to the originating station.

See network topology.

A network that conveys data only among local hosts.
Note: Even if the local hosts are connected to more than one other network, these hosts do not carry traffic between these other networks. [2382-pt.35]

1. A collection of equipment and physical transmission media that forms an autonomous whole and that can be used to interconnect systems for purposes of communication.
2. Specifically, a collection of open system interconnection (OSI) end systems and intermediate systems under the control of a single administrative domain and using a single network access protocol.
Note: Examples of subnetworks are… (Read More →)

The network of switching systems, interconnecting facilities, and equipment provided by an exchange carrier (EC) to provide telecommunications services between the exchange office (EO) and interexchange carrier point of termination (IC-POT). [T1.508-1998]

1. A communications network, such as the public switched telephone network, in which any user may be connected to any other user through the use of message, circuit, or packet switching and control devices.
2. Any network providing switched communications service.
