How The System Limits Interact; Maximum Device Counts And Memory Requirements - 3Com 3C10122 - NBX Business Telephone Installation Manual

How the System
Limits Interact
Maximum Device
Counts and Memory
Requirements
As you add devices to an NBX system, you must keep in mind all of these
limitations:
Total device limit for the system
■
Individual device limit for certain device types
■
License limit for certain device types
■
System memory
■
Example: Your V3001 Analog system has the optional memory upgrade
installed. It is licensed for 1500 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 978 additional
devices (1500–522).
You want to configure 200 Attendant Consoles, but, because the
■
individual device limit for Attendant Consoles is 100, you can
configure only 100 Attendant Consoles.
The total device count is now 622. You can configure 878 additional
devices (1500–622).
You want to add Virtual Tie Lines (VTLs), but you can add only 48
■
because that is the maximum license level available for VTLs.
VTLs do not count toward the device limit, so the total device count
remains at 622. So, after you add 48 VTLs, you can still configure up
to 878 additional devices.
This section lists each NBX device and application with information on
whether it counts toward the total device count and the maximum
number allowed per NBX system and shows which devices and features
require the optional memory upgrade on V3001 systems. The maximum
number for each device and application assumes that there are no other
types of devices connected to the system — the total device limit always
takes precedence.
