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. Licensed Device Limits Certain devices and applications have limits that are governed by licenses. Device licensing is explained in detail in "Device Licenses" on page 72. Your 3Com NBX Voice-Authorized Partner can provide details on available incremental device licences.
