Explanation:
The PBX first searches local extensions for a matching number. If a dialed number is not found at the local
PBX, the call can then be sent to a remote PBX, and the remote PBX checks the TIE Line Routing Table for
a corresponding entry.
Case 1:
Extension 1012 of PBX-1 dials extension number "1011".
®
The dialed number is found at the local PBX, and extension 1012 of PBX-1 is connected to extension 1011
of PBX-1.
Case 2:
Extension 1012 of PBX-1 dials extension number "1033".
®
The dialed number is not found at the local PBX, so the call is redirected to the specified TIE Line, and
extension 1012 of PBX-1 is connected to extension 1033 of PBX-2.
Case 3:
A public CO line call directed to extension 1033 arrives at PBX-1.
®
The target extension number is not found at the local PBX, so the call is redirected to the specified TIE Line,
and the call is connected to extension 1033 of PBX-2.
