TIE Line Network
A TIE line call is sent to
PBX-2 from PBX-1. If
the number sent from
PBX-1 has the PBX
code of PBX-2 "952",
the call will be
received
at the corresponding
extension of PBX-2
(e.g., 1011 of PBX-2).
If not, PBX-2 checks
the number in the TIE
Line Routing and
Modified Table of
PBX-2.
If the match is found in
the table, the call will
be modified according
to the table and
send to
the corresponding
PBX (PBX-3).
The number sent from
PBX-2 "953-1011" has
the PBX code
of PBX-3
"953". The call is
received at extension
"1011" of PBX-3.
Note
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.
