14.00 Tie Lines
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 in 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.
