b) PBX Code Method (Access with 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 has the PBX code of the PBX.
3. TIE Line and Trunk Connection
To connect the TIE line with the trunk, the following patterns are available:
1) Trunk-to-TIE Access
2) TIE-to-Trunk Access
3) Trunk-to-TIE-to-Trunk Access
3.1 Trunk-to-TIE Access
It is possible to assign an extension of another PBX as the destination of incoming
trunk calls to the own PBX.
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.,
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 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.
