MultiSite Backup Tool enables you to automate the task of archiving
NBX systems. You can schedule backups of one or many NBX systems
and create a backup schedule for each NBX location.
■
NBX Dial Plan Editor provides a visual interface for editing an NBX
dial plan. It lets system administrators navigate and execute complex
commands with the click of a mouse.
NBX Licensing
Each NBX system is shipped with a total-device-limit license that controls
the total number of devices that you can configure on the system.
However, there are other factors to consider when determining what
your system can support. Your configuration must conform to
all of these
limits:
■
The limit imposed by the total system license (explained next)
■
The individual limits on certain device types (explained later in this
topic)
■
The license requirements for some hardware and software
A V3000, V3001R, or V5000 system operating in SIP mode has further
device limit considerations. The NBX 100 does not support SIP mode
operations. For more information, see the
NBX Administrator’s Guide .
What Counts Toward the Total Device Limit?
NBX systems count many physical devices and certain software
applications as devices toward the total device limit:
■
Physical Devices — Each 3Com Telephone, each Analog Terminal
Adapter, each channel on a Digital Line Card, and each port on an
Analog Line Card counts as one device. Physical device limits are listed
in
Table 13 .
■
Software “Devices” — Each NBX Media Driver port counts as one
device. Each installation (client) of the pcXset Soft Telephone
application counts as one device.
What Does NOT Count Toward the Total Device Limit?
The NBX systems do not count most applications toward the total device
limit, although some may be governed by license limits. Examples: NBX
Messaging voice mail ports and automated attendant ports, Call Park
zones, and System Speed Dials.
