1.30.1.3 TIE Line Programming
Description
To Make a TIE Line Call
The TIE Line Routing and Modification Table is referenced by the PBX to identify the trunk 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 dialled number.
There are two system programmes for the tables:
TIE Line Routing Table: used to assign the leading numbers (PBX code or extension number) and trunk group
hunt sequence.
® 11.1 [9-1] TIE Table— Leading Number
TIE Modify Removed Number of Digits/Added Number: used to remove digits from and add a number to
the dialled number of the TIE line call. This modification may be needed depending on the TIE line network
configuration.
