1.30.1 TIE Line Service
Description
A TIE line is a privately leased communication line between two or more PBXs, which provides cost effective
communications between
company members at different locations. The TIE lines can be used to call through
the PBX to reach another switching system (PBX or telephone company). By using TIE lines, the PBX can
support not only communications with the public network but with other company members in the private
network where the PBX is included.
