A set of signaling link(s) directly connecting two signaling points. [T1.110-1987]

1. An assembly of signaling information pertaining to a call that includes, but is not limited to, management transactions, that is transferred (between signaling points) as an entity. [T1.226-1992]
2. An assembly of signaling information that pertains to a call management transaction, and the like and that is transferred as an entity. [T1.110-1987]

At a given signaling point, the process that decides, for each incoming message, whether the signaling point is destination point or if it should act as signaling transfer point for that message, and accordingly, whether the message should be handed to (signaling) message distribution or to (signaling) message routing functions. [After T1.110-1987] [After T1.226-1992]

The process of determining upon receipt of a signaling message at its destination point, to which user part the signaling message is to be delivered. [T1.110-1987]

Functions that, at the actual transfer of a message, direct the message to the proper signaling link or user part. [T1.226-1992]
Note: The message handling functions include functions for message distribution, message discrimination, and message routing.

The signaling link or consecutive links connected in tandem that are used to convey a signaling message from an originating point to its destination point. [T1.110-1987] [T1.226-1992]

The process for selecting, for each signaling message to be sent, the signaling link to be used. [T1.110-1987]

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]
