A physical connection to the entity being controlled or monitored. [T1.317-1993]

A unique address code that identifies a service provider (SP) within a signaling network. [T1.234-1993]

A state in a basic call-state model. [T1.667-1999]

A subscriber's entrance to the telecommunications network. A logical view of this point of access has a relationship with the termination point as defined in the generic network model (GNM). In practice, this may be physically represented by a line card connected to the subscriber's access loop. For mobile communication services, where channels are assigned dynamically as the user moves,… (Read More →)

In a telecommunications system, the physical interface between the local access and transport area (LATA) access and inter-LATA functions.
Note: The POI is used to establish the technical interface, the test points, and the points of operational responsibility. Synonym interface point.

A physical layer within a local access and transport area (LATA) at which an inter-LATA carrier establishes itself for the purpose of obtaining LATA access and to which the local exchange carrier provides access services.

The point of demarcation between (exchange) carriers that establishes the technical interface, test points, and division of operational responsibility. [Tl.501-1988] [T1.502-1988] [T1.104-1988] [T1.306-1989]

In infrared transmission systems, a steady infrared light that is used (a) to assist the transmitter in locating a receiving station and (b) for keeping the transmitted light pointed in the proper direction for satisfactory reception. [From Weik '89]

A source of electromagnetic radiation such that (a) the source is so distant from a point of observation or measurement of the radiation that the wavefront of the radiation is a planar rather than a curved surface, regardless of the shape of the source, (b) the size or shape of the source has no influence on the shape of the… (Read More →)

A distinctive type of multipoint connection, composed of a central connection endpoint (central CE) and other, peripheral, CEs, and in which data originating from the central CE are received by all other CEs, and data originating from peripheral CEs are received only by the central CE.
