When a TIE line call is sent to a PBX from another PBX, first the PBX modifies the number
sent to the PBX according to the assignment for each CO line port of the PBX: the
removed number of digits from and/or added number to the number sent to the PBX is
determined by the assignment. Then the PBX starts to check the number whether the
number has the PBX code of the PBX.
