NBX Licensing 57
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 (4 x 180),
and thus the system can support a maximum of 720 not 1500 analog line
ports.
Features and System
Performance
Some combinations of features on NBX 100 systems and V3000 systems
that do not have the optional memory upgrade installed can create
system performance issues. These notes describe system configuration
issues that affect performance. Performance on V3001R, V5000, and
V3000 systems that have the optional memory upgrade installed are not
affected by these features performance limits.
■
A V3000 without the optional memory upgrade can provide
acceptable performance for the maximum of 250 devices if the
combined number of ACD Groups plus Hunt Groups plus Calling
Groups in the system is less than 70. Alternatively a V3000 system
supports the maximum number of ACD Groups plus Hunt Groups plus
Calling Groups, 100, if the number of devices in the system is less
than 100.
■
An NBX 100 can provide acceptable performance for the maximum of
200 devices if the combined number of ACD Groups plus Hunt
Groups plus Calling Groups in the system is less than 50.
Guidelines:
■
5 devices for every ACD Group plus Hunt Group plus Calling Group
■
75 Phantom mailboxes for every ACD Group plus Hunt Group plus
Calling Group
or
500 Account codes for each ACD Group plus Hunt Group plus Calling
Group. For example, on a V3000 system, to have 75 Groups and 250
devices , you can have no more than 2500 Account codes and 150
Phantom mailboxes.
