5.3 Using the LCD/Buttons and Web for Conguration
You use the various configuration settings to adjust audio levels and processing options, set the
ISDN parameters, etc.
You may use either the front panel LCD/button user interface on the Nx12 main unit or the
Web interface to access configuration options. e Web interface offers the full set of configura-
tion options, while the LCD/button includes only the most often needed items.
The LCD/Button User Interface
Each of the three buttons below the LCD display calls up the menu item group associated with
the button’s name.
Pressing any menu button (Audio, Telco, or System) twice displays the Status screen.
Menu Navigation & Item Selection
After you select a menu group, you can use the ∆ and ∇ arrow buttons to scroll through the
available items. You may select a highlighted item for modification by pressing the OK button.
Once an item is selected, you can use the ∆ and ∇ arrow buttons to can change the value of the
setting.
When you reach the value you desire, press the OK button again to lock it in and return you to
the item selection/scroll mode.
The Web User Interface
A Web Browser can be used to remotely configure and administer the system. All front panel
configuration options are duplicated on the web pages. Certain advanced options such as enter-
ing ISDN DNs/SPIDs and Livewire configuration require the Web interface.
You can connect a PC directly to the Nx12 with an Ethernet cross-cable. Or you can connect
both the PC and the Nx12 to an Ethernet switch or hub.
Important Note
If Livewire has been enabled, there will be a lot of network trac generated by the Nx12.
Some PCs, switches, hubs, and routers that are not multicast-aware will not be able to handle
the volume and Web communication will not be possible.
Normally, you would use the Web interface to switch o the Livewire streams, but since you
can’t communicate with the Web interface, you will have to rst disable the Livewire streams
from the front panel LCD/button interface. The rst item under the Audio menu is what you
need.
