Conditions
• A CO line which is used for a private network should be assigned "Private" as the networking type.
(→ 1.9.10 INCOMING CALL FEATURES)
• To establish a QSIG network (→ 1.13.18 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 the KX-TDE
series PBX and KX-TDA series PBX.
[TIE Line Network Connection Example]
• TIE Line Call by Own PBX Extension Number
TIE line calls can be made using your own PBX extension numbering scheme (1–64).
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.
