Multi-Connection Networking Survivability; Simplified Isolated Mode - Panasonic KX-NSX1000 Manual

4.2.3 Multi-connection Networking Survivability

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 Multi-connection 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 Multi-connection
network. It is also possible to connect a Multi-connection network to other PBXs via QSIG. In an H.323
QSIG network, the Multi-connection network appears as one PBX. The NSX Server Unit represents the
Multi-connection network.

4.2.3.1 Simplified Isolated Mode

The Survival Gateway feature (Simplified Isolated Mode) is a feature that activates when the Expansion
Gateway (hereafter referred to as EXP-GW) enters an isolated state due to an operation halt of the NSX or
due to a network error between the sites.
This feature is a limited service for actions such as sending and receiving calls and is operational for 30
days after transitioning to Simplified Isolated Mode.
The operation of Simplified Isolated Mode is as follows.
