Incoming CO Line Call Features

1.1.1.1 Incoming CO Line Call Features—OVERVIEW
Description
Each CO line functions as either a public line or a private line. Private lines are used to connect different
PBXs and form a private network (→ 1.27.1 TIE Line Service), while public lines connect a PBX to a public
network, i.e., the telephone company. Certain PBX features are available depending on the networking type
(public or private) of each CO line.
