1.26 Networking Features
• To establish a QSIG network (→ 1.26.4 QSIG Standard Features), each ISDN (QSIG) connection in a
TIE line network must have the port on one Panasonic Hybrid IP-PBX assigned as a master port, and
the port on the other Panasonic Hybrid IP-PBX assigned as a slave port.

• [TIE Line Call by Own PBX Extension Number]
TIE line calls can be made using your own PBX extension numbering scheme (1–64).

Outside Caller
Dials "123-4567".
Explanation:
The PBX first searches local extensions for a matching number. If a dialled 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 dialled number is found at the local PBX, so 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 dialled 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.
