1.29 Networking Features
•
To establish a QSIG network (→ 1.29.4 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 Call by Own PBX Extension Number]
When only two PBXs are connected in a network (not including a VoIP network), both PBXs can have
extensions with the same leading number.

Dials "1013".
Explanation:
If a dialled number is not found at the local PBX, the call can be sent to the remote PBX.
When an extension number is dialled, the PBX first searches local extensions for a matching number.
If there is no match, the PBX then checks the TIE Line Routing Table for a corresponding entry. If an
entry is found, the call is sent to the connected PBX.
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 "1013".
→ 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 1013 of PBX-2.
