Transmission Facilities
Transmission facilities provide the communication paths that carry user and network control information between nodes in a network. In general, transmission facilities consist of a medium (e.g., free space, the atmosphere, copper 2 or fiber 3 optic cable) and electronic equipment located at points along the medium. This equipment amplifies 4 (analog systems) or regenerates 5 (digital systems) signals, provides termination functions at points where transmission facilities connect to switching systems, and may provide the means to combine many separate sets of call information into a single "multiplexed" signal to enhance the transmission efficiency.
Transmission Impairments
Transmission impairments is the degradation 6 caused by practical limitations of channels (e.g., signal level loss due to attenuation 7, echo, various types of signal distortion, etc.), or interference induced from outside the channel (such as power-line hum or interference from heavy electrical machinery).
Transmission Medium
Transmission medium is any material substance or "free space" (i.e., a vacuum) that can be, or is, used for the propagation of suitable signals, usually in the form of electromagnetic (including light waves), or acoustic 8 waves, from one point to another; unguided in the case of free space or gaseous 9 media or guided by a boundary of material substance.
Transport Services
Transporrt Services are network switching, transmission and related services that support information transfer capabilities 10 between originating and terminating access service facilities.
Trunk
In a network, a trunk is a communications path connecting two switching systems used to establish end-to-end connections between customers.
Twisted Pair
Twisted pair is the most common type of transmission medium, consisting of two insulated copper wires twisted together. The twists or lays are varied 11 in length to reduce the potential for interference between pairs. In cables greater than 25 pair, the twisted pairs are grouped and bound together in a common cable sheath. See unshielded twisted pair.
