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 trunk 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.

1.26 Networking Features
A TIE line call is sent to PBX-2 from
1
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., 1011of 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
2
call will be modified according to the
table and send to the corresponding
PBX (PBX-3).
The number sent from PBX-2 "953-
3
1011" has the PBX code of PBX-3
"953". The call is received at
extension "1011" of PBX-3.
