15.1.13 PRIVATE NETWORK FEATURES
CO Line
Outside Caller
Dials "123-4567".
Explanation:
The PBX first searches local extensions for a matching number. If a dialed number is not found at the local
PBX, the call can then be sent to a remote PBX, and the remote PBX checks the TIE Line Routing Table for
a corresponding entry.
Case 1:
Extension 1012 of PBX-1 dials extension number "1011".
→ The dialed number is found at the local PBX, and extension 1012 of PBX-1 is connected to extension
1011 of PBX-1.
Case 2:
Extension 1012 of PBX-1 dials extension number "1033".
→ The dialed number is not found at the local PBX, so the call is redirected to the specified TIE Line, and
extension 1012 of PBX-1 is connected to extension 1033 of PBX-2.
Case 3:
A public CO line call directed to extension 1033 arrives at PBX-1.
→ The target extension number is not found at the local PBX, so the call is redirected to the specified TIE
Line, and the call is connected to extension 1033 of PBX-2.
–
System programming is required to enable this feature.
–
If a dialed number is not found at a remote PBX, the call cannot be redirected to the local PBX to search
for a matching number.
Conditions
•
A CO line which is used for a private network should be assigned "Private" as the networking type. (→
10.1.11 INCOMING CALL FEATURES)
•
To establish a QSIG network (→ 15.1.18 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-NS series, and
KX-NCP series, KX-TDE series, and KX-TDA series PBXs.
