Note
When a TIE line call is sent from one PBX to another, the receiving PBX first modifies the received
number according to the assignment for the trunk port: the number of digits removed, and the number
added, are determined by this assignment. Then the PBX checks whether the completed number is
an existing extension number at that PBX.

PBX-2
A TIE line call is sent to
1
PBX-2 from PBX-1. If the
number sent from PBX-1
is an extension number of
PBX-2 (e.g., 2011), the
3
call will be received at
extension "2011". If not,
Extn. 3011
PBX-2 checks the
number in the TIE Line
Routing and Modified
2 3011
Table of PBX-2.
If the match is found in
2
the table, the call will be
modified according to the
Extn. 2011
table and send to the
corresponding PBX
(PBX-3).
The number sent from
3
PBX-2 "3011" is an
extension number of
PBX-3. The call is
received at extension
"3011".
