TIE Line Programming
To Make a TIE Line Call
The TIE Line Routing and Modification Table is referenced by the PBX to identify the CO line route when an
extension user makes a TIE line call.
It is necessary to make unified tables with all PBXs in the TIE line network.
The routing pattern appropriate for each call is decided by the dialed number.
There are two system programs for the tables:
TIE Line Routing Table: used to assign the leading numbers (PBX code or extension number) and trunk group
11.1 [9-1] TIE Table—
TIE Modify Removed Number of Digits/Added Number: used to remove digits from and add a number to
the dialed number of the TIE line call. This modification may be needed depending on the TIE line network
