TIE Line Network
1
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.
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).
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.
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 CO line 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.
Conditions
•A CO line which is used for a private network should be assigned "Private" as the networking type. (®
9.1.10 INCOMING CALL FEATURES)
•To establish a QSIG network (® 13.1.18 PRIVATE NETWORK FEATURES—QSIG), each ISDN (QSIG)
connection in a TIE line network must have the port on one PBX assigned as a master port, and the port
on the other PBX assigned as a slave port. PBXs that support this feature are KX-TDA series, KX-TDE
series, and KX-NCP series PBXs.
