NBX Licensing 59
NBX Licensing
Each NBX system is shipped with a 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 system operating in SIP mode has further device limit considerations.
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 on page 63 .
■
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.
Individual Device
Limits
Certain individual device types are limited to a maximum per system
because of internal product rules. For example, the NBX Analog Line Card
has 4 ports. Although each of these ports counts as a device, the NBX
system architecture limits the system to 180 Analog Line Cards and thus
the system can support a maximum of 720 (4 x 180) not 1500 analog line
ports.
