To Receive a TIE Line Call
a.
Extension Number Method (Access without PBX Code)
[Example]
Extn. 1011
Dials "3011".
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 CO line 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.
b.
PBX Code Method (Access with PBX Code)

A TIE line call is sent to
PBX-2 from PBX-1. If the
number sent from PBX-1 is
an extension number of
PBX-2 (e.g., 2011), the call
will be received at
extension "2011". 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 "3011" is an
extension number of
PBX-3. The call is received
at extension "3011".
