1.27 Networking Features
After modifying the number, the PBX will check to see if this modified number is stored in its Extension
Numbering Plan or Other PBX Extension list (see "Flexible Numbering" below). If the PBX cannot
handle the call itself (when a call is meant for an extension of a different PBX, for example), it refers to
the TIE Line Routing and Modification Table in order to send the call down the TIE line.
Flexible Numbering
Flexible Numbering contains several numbering plans which will be referred to after an extension user
dials a number, or after an incoming TIE line call is modified by the Incoming Number Modification
Table.
If the dialed number or modified number is found in the Extension Numbering Plan or Feature
Numbering Plan, the PBX will send the call to one of its own extensions or access the appropriate
feature, respectively.
If the modified number is found in the Other PBX Extension list, the PBX will check the TIE Line Routing
and Modification Table for instructions on how to send the call down the TIE line.
2.
Making and Receiving TIE Line Calls
To make a call to an extension of another PBX, an extension user simply dials an extension number.
