Terms and Conventions Used
Centrex line). However, in actual usage, the terms
line
and
trunk
are
often applied interchangeably. In this book, we use
line/trunk
and
lines/trunks
to refer to facilities in general. Specifically, we refer to
digital
facilities
. We also use terms such as personal line, ground-start trunk,
Direct Inward Dialing (DID) trunk, and so on. When you talk to your local
telephone company central office, ask them which terms they use for the
specific facilities they connect to your system.
Some older terms have been replaced with newer terms. The following
