3Com NBX 100 Installation Manual page 75

Example 1— All devices in the same License Group: You purchase
and install a package of ten Group 2 Licenses on your NBX system and
then add five 3102 Business Telephones, one 3103 Manager's Telephone
and one 3105 Attendant Console for a total of seven Group 2 devices.
The system has three Group 2 licenses still available.
Example 2 — Borrowing from the next highest License Group: You
add a 3101 Basic Telephone (Group 1 device) to your NBX system, which
has three Group 2 licenses available. You do not add a Group 1 license to
the system. The system checks for the availability of a Group 1 license.
Since no Group 1 licenses are available, the system assigns a Group 2
license to the 3101 Basic Telephone. The system now has two Group 2
licenses available.
Example 3 — Borrow from the highest License Group: You add two
3100 Entry Telephones (Group 0 device) to your NBX system, which has
two Group 2 licenses available. You do not add a Group 0 license to the
system. The system checks for the availability of a Group 0 license, then
checks for the availability of a Group 1 license, and since there are no
Group 0 or 1 licenses available, assigns the Group 2 licenses to the 3100
Entry Telephones. The system now has no licenses available.
Example 4 — Dynamic License Group Adjustment: You add another
3103 Manager's Telephone (Group 2 device) to your an NBX system that
has no licenses available in any group. The system will not enable the new
telephone. You could add another Group 2 license, but it would be more
cost-effective to add a less expensive Group 0 license instead. After you
add a Group 0 license, the system automatically reassigns licenses in this
manner:
Releases one of the Group 2 licenses that was assigned to one of the
3100 Entry Telephones.
Assigns the new Group 0 license to the 3100 Telephone.
Assigns the released Group 2 license to the new 3103 Telephone.
The system now has no licenses available.
Example 5 — Manual License Group readjustment: You add another
3103 Manager's Telephone (Group 2 device) to an NBX system that has
no licenses available in any group. Instead of adding a Group 0 license, as
shown in Example 4, you could manually remove one of the telephones
from the system to free a license. For example, you could use the NBX
