TIE Line Features
374 Features Guide
TIE Line and Outside (CO) Line Connection
Description
TIE Lines can be used to minimize the cost of calls to a distant location outside of the TIE Line
Network. A long distance call from one location may be a local call from another location. This
fact should be considered before making a long distance call. If the destination of the long
distance call is outside of the TIE Line Network, extension users first make a call to a distant
PBX via TIE Line and then can make a local CO call to the final destination through that PBX.
