4.2.2 Network Type Comparison
Description
This section summarises the main differences between the two methods for connecting PBXs over an IP
network: One-look networking and H.323 (VoIP) QSIG networking. It also explains which situations each type
of network is suited for.

For non-KX-NS1000 PBXs, requirements may differ.
When to choose a One-look network
If the network will consist only of KX-NS1000 PBXs and a private IP network is feasible, then a One-look
network is probably the better option. A considerable amount of setup is done automatically by the PBXs, so
setup and maintenance is much simpler. All units can be programmed from one location. This simple setup
and programming means that the PBX network can be expanded with considerably less effort.
Extensions are managed so they behave as if they were all connected to one PBX, which eliminates the need
to manage information such as PBX access codes.
However, resource sharing also requires a lot of bandwidth, since the Master unit must constantly monitor and
manage the status of the Slave units and connected devices. Therefore, if bandwidth is a concern, an H.323
QSIG network may be preferable.
When to choose an H.323 QSIG network
If the network will include non-KX-NS1000 PBXs (e.g., KX-TDE200, KX-NCP500), then an H.323 QSIG
network is necessary.
An H.323 QSIG network is preferable if strict resource separation between sites is necessary. Although it is
possible to reserve certain resources for certain extension users in a One-look network, the default is to share
resources. On the other hand, in a QSIG network, resources are not available to extension users of other PBXs
without explicit programming.
Programming and configuring an H.323 QSIG network is much more complex than a One-look network.
It is also possible to connect a One-look network to other PBXs via QSIG. In an H.323 QSIG network, the
One-look network appears as one PBX. The Master unit represents the One-look network.
