How the Three Limit
Types Interact
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: voice
mail ports, automated attendant ports, Call Park zones, System Speed
Dials, and any other item with "None" in the second column in
on page 49.
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
SuperStack 3 system architecture limits the system to 180 cards, and thus
720 (not 1500) ports.
Individual device limits are listed in
Certain individual devices and applications have count limits that are
governed by licenses. (See the 3Com Price List or your 3Com NBX
Voice-Authorized Partner for details on available incremental licences.)
Example: You can install a license for 2 Virtual Tie Lines (VTLs), and then
add incremental 2-unit licenses up to a limit of 8 VTLs on an NBX 100
system or up to 48 VTLs on a SuperStack 3 NBX system.
As you add devices to an NBX system, you must keep in mind all three of
these limitations:
Total device limit for the system
■
Individual device limit for certain device types
■
License limit for certain device types
■
Example: Your SuperStack 3 NBX system has a license for 750 total
devices and you want to configure 450 telephones:
You configure 6 NBX Analog Line Cards, and 12 NBX Analog Terminal
■
Cards (for analog telephones and FAX machines).
The total device count is now (6 x 4) + (12 x 4) = 72.
You then configure 450 3Com Telephones.
■
The total device count is now 522. You can configure 228 additional
devices (750–522).
