Panasonic KX-NS500, Installation Manual

Page: 31 / 338

The networked system is called a One-look network. In a One-look network, a KX-NS1000 PBX serves as the
Master unit, which controls the other PBXs, known as Slave units.
For more information about One-look network, refer to "8.2 Information about Using One-look Network".
*1 NS-Net is a network protocol only used for Panasonic products.
H.323 QSIG network
If the network will include non-KX-NS500 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. In a QSIG
network, resources are not available to extension users of other PBXs without explicit programming.
For details about programming the H.323 QSIG network, refer to "5.5 Programming an H.323 QSIG
Network".
