which explain many system
features and procedures in greater detail. Because private networks leverage
existing communications system features as well as introducing new ones, this
guide focuses not on a thorough discussion of system management and system
features but rather on how they apply to private networks. “Related Documents”

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
