17.1 PBX Configuration—[9-1] Private Network—
TIE Table
A TIE line is a privately leased communication line between two or more PBXs, which provides cost effective
communications between company members at different locations.
A maximum of 32 TIE Line Routing and Modification Tables can be programmed. It is necessary to make
unified tables with all PBXs at different locations in a TIE line network in order to identify the trunk route to
be used when an extension makes or receives a TIE line call.
There are two types of routing methods: the Extension Number Method, where all extensions in the network
are given a unique extension number; and the PBX Code Method, where each PBX is given a unique code,
which is dialled before the extension number to call an extension at another PBX.
Two priority sets (from a total of 8) are displayed at a time. To display other priority sets, click the applicable
tab.
Using a private network, up to 8 PBXs can share one voice mail system (centralised VM) connected to
another PBX. This can provide voice mail for extensions attached to any of the PBXs in the network.
