TIE Line Features

TIE Line Service

Description
A TIE line is a privately leased communication line between two or more PBXs, which
provides effective communications between company members at different locations.
TIE lines can be used to call through KX-TD500 to reach another switching system (PBX or
CO). By utilizing the TIE lines, the KX-TD500 can support not only communications with the
public network but with other locations of the company in the private network of which your
KX-TD500 can be a part.
To make a call to a person at a distant company location, an extension user must first obtain
the appropriate TIE line to that person's PBX, and then dial the extension number only or a
location number plus extension number.
