2.2 To Receive a TIE Line Call
a) Extension Number Method (Access without PBX Code)
[Example]
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 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 is an extension number of the PBX.
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".
