3.1 TIE Line Features
Outside (CO) Line and TIE Line Connection
Description
TIE lines are usually used to link two or more distant locations where high volume calling
traffic exists. However, a person at a location outside of the TIE Line Network can also use it
by first making a CO call via public network to the nearest point of TIE Line Network for the
purpose of saving the toll call charge.
