TIE LINES Ñ Calling from TIE to CO
DescriptionTIE 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 call to a distant PBX via TIE
Line and then can make a local CO call...

TIE LINES Ñ Calling from CO to TIE
DescriptionTIE 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.
