Guidelines
Three kinds of limits govern the number of devices that you can include
when you configure a SuperStack 3 NBX system or an NBX 100 system:
■
Total device limits per system
■
Individual device limits on certain devices
■
Licensed device limits on certain devices
Total Device Limits on
the NBX System
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:
■
Total on the SuperStack 3 NBX — 250 devices (factory default)
To add more devices to a 250-device SuperStack 3 NBX system, you
can purchase additional licenses in 125-device or 250-device
increments, up to a maximum of 1500 devices. (For the current device
and license configuration on your system, see
NBX NetSet >
Operations > Licenses as well as the Usage Report accessible from
the Licenses screen.)
■
Total on the NBX 100 — 200 devices (factory default and maximum
device limit)
For support above 200 devices, you must purchase a SuperStack 3
NBX Call Processor.
CAUTION: 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
What Counts Toward the Total Device Limit?
The 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. Additional physical device
limits are listed in
Table 5 on page 49 .
■
Software “Devices” (Applications) — The NBX Media Driver
application counts as one device, and each installation (client) of the
pcXset Soft Telephone application counts as one device.
