Terms and Conventions Used 0
The terms described here are used in preference to other, equally acceptable
terms for describing communications systems.
Lines, Trunks, and Facilities
Facility is a general term that designates a communications path between a
telephone system and the telephone company central office. Technically, a
trunk
connects a switch to a switch, for example, the MERLIN LEGEND
Communications System to the central office. Technically, a
line is a loop-start
facility or a communications path that does not connect switches, for example, an
intercom line or a Centrex line. However, in actual usage, the terms
line and trunk
are often applied interchangeably. In this guide, we use lines/trunks and line/trunk
to refer to facilities in general. Specifically, we refer to digital facilities. We also use
specific terms such as personal line, ground-start trunk, DID trunk, and so on.
When you talk to your local telephone company central office, ask about the terms
they use for the specific facilities they connect to your system.
Some older terms have been replaced with newer terms. The following list shows
