22 ABOUT THIS GUIDE

INTRODUCTION

The NBX Administrator’s Guide explains how to configure your NBX® system. This chapter describes these topics:

■ Network-based Telephony

■ NetSet Administration Utility

For information about how to install hardware components, see the

NBX Installation Guide.

Network-based Telephony

3Com Networked Telephony Solutions merge telephony with networking by delivering business telephone service over a data network.

To a telephone user, a 3Com Telephone is an office telephone. You can use it to make and receive calls, transfer calls, park calls, use voice mail, and so on. Inside, the 3Com Telephone is a network device that can communicate over the LAN using Ethernet frames or IP packets. The telephone also includes a LAN port. You can connect your computer to your network through the telephone and avoid the need for a second LAN connection at the desktop.

The core of the system is the Call Processor. The Call Processor manages the processes of making and receiving calls, providing voice mail and Auto Attendant services, and responding to requests for special services, such as access to the NBX NetSet administration utility, Computer Telephony Integration (CTI) services, or the system’s IMAP (Internet Message Access Protocol) server.

24 CHAPTER 1: INTRODUCTION

NetSet Administration Utility

the NBX NetSet utility is a browser-based interface that you use to configure and manage the system. the NBX NetSet utility requires any of these browsers:

■ Microsoft Internet Explorer 5.5 or higher

■ Netscape Navigator 7.0 or higher

■ Mozilla Firefox 1.0 or higher

Figure 1 shows a sample NetSet window. The navigation menu is on the

left of the window. Place the cursor over any of the functions to expand the view of that function and display all the associated options.

Figure 1 NetSet Utility - Page Zones Window

Systems present the NBX NetSet utility through an embedded web server that is integrated in the system software. NetSet passwords grant system administrators and telephone users different levels of access privileges. Individual telephone users can view or change their personal settings, such as personal speed dial lists, off-site notification settings, and ringing tones. System administrators can manage user profiles and devices, change system parameters, such as dial plan settings, and upgrade the system software.

NetSet Administration Utility 25

NetSet User Interface Figure 2 shows the NBX NetSet utility user interface. Each NetSet user

interface page contains common elements.

Navigation Menu

■ Title Bar — The NBX trademark followed by the system (host) name.

■ Navigation Route Bar — The current page location, which is the

selected navigation menu item and the selected submenu item.

■ Navigation Menu — A list of all navigation groups in the NBX NetSet

user interface. The navigation menu is partially or fully disabled under certain conditions. These conditions include:

■ System backup in progress: All menus are disabled.

■ System restore in progress: All menus are disabled.

■ System shutdown: All menus are disabled.

■ No system license: Only Licensing and Upgrades and System

Maintenance menus are enabled.

■ Tab Menu Bar — Displays when you click a menu item or submenu

item, or when you click a link to a record.

■ Help — Quick help text plus a button that invokes detailed help.

26 CHAPTER 1: INTRODUCTION

SYSTEM SETTINGS

This chapter provides information about how to configure settings, whose effects span the entire system, and includes these topics:

■ Auto Discovery

■ Enable Features System-Wide

■ System Identity

■ Business Information

■ Date and Time

■ IP Settings

■ Audio Settings

■ Timers

■ Multicast Addresses

For more information about these topics and configuration procedures, see the online Help.

Auto Discovery The Auto Discovery feature simplifies initial system configuration by

adding information about new devices to the configuration database. Devices include telephones, Analog Line Card ports, Digital Line Card channels, Analog Terminal Adapter ports, 3Com Attendant Consoles, and virtual devices, such as the pcXset Soft Telephone and the ConneXtions H.323 Gateway. Devices must have network connectivity with the Call Processor.

After the system discovers a device, the Auto Discovery process does not find that device again. To remove a device from the system database, use the NBX NetSet utility to remove the device and its database record manually. Note that if you delete a telephone user, the system does not delete the device associated with that user.

28 CHAPTER 2: SYSTEM SETTINGS

The system does not discover licensed devices until you enter the appropriate Group License. For more information about Group Licensing, see the NBX Installation Guide.

Ta bl e 4

summarizes Auto Discovery actions for system components.

Tab le 4 Auto Discovery Actions on System Components

Component Auto Discover Action

Analog Line Card and V3000 analog line ports

Gathers configuration information from each port on the card, assigns a default extension, and enters the information into the configuration database.

Digital Line Card Gathers configuration information from the card, assigns a default extension, and

enters the information into the configuration database.

After you Auto Discover the Digital Line Card, you might need to edit the dial plan to configure Direct Inward Dial (DID) numbers.

3Com Telephones

Analog Terminal Cards

Analog Terminal Adapters

V3000 ATA port

Gathers configuration information from the telephone, assigns a default User Profile labeled new user, assigns the next lowest available extension number to the profile, and enters the information into the configuration database.

Auto Discover Telephones finds both Analog Terminal Cards and Analog Terminal Adapters.

By default, the Auto Discover process assigns extension number 1000 (4-digit dial plan) or 100 (3-digit dial plan) as the first telephone extension. You can use the NBX NetSet utility to specify a new extension starting number. To simplify Auto Attendant configuration, start a range at a base number, for example, 1000/100, 2000/200, 3000/300, or 4000/400. The default Auto Attendant assumes that extension 1000 (4-digit dial plan) or 100 (3-digit dial plan) is the extension of a human attendant (receptionist).

3Com Attendant Console Finds and configures any installed 3Com Attendant Consoles. The system maps the

first 100 existing telephones, except for the extension that is associated with the Attendant Console, to Attendant Console buttons. The lowest extension is automatically associated with the Attendant Console. Typically, you enable Auto Discover Attendant Consoles after you have installed all your telephones.

pcXset Soft Telephone

Enables the Auto Discover feature on installations of the pcXset PC Telephone Client when the following conditions are true:

■ The pcXset PC Soft Telephone program is running on the host PC.

■ The pcXset PC Soft Telephone host computer is connected to the network.

■ You have entered the proper license key into the NBX NetSet utility.

ConneXtions H.323 Gateway Configures line card port settings when the following conditions are true:

■ The ConneXtions H.323 Gateway program is running.

■ The ConneXtions H.323 Gateway host computer is connected to the network.

■ You have entered the proper license key into the NBX NetSet utility.

Auto Discovery 29

Initial System

Configuration

To use the Auto Discover feature for initial system configuration:

1 Log in to the NBX NetSet utility using the administrator username and

password.

2 Click

System-Wide Settings > Enable Features System-Wide.

3 Verify that the Extensions Start At field is set to what you want, and then

click Apply.

For a 4-digit dial plan, extensions start by default at 1000. For a 3-digit dial plan, extensions start at 100.

Do not specify a starting extension that begins with zero (0), which will cause the Auto Discover process to fail.

4 Click

System-Wide Settings > Auto Discovery.

5 Select the check box for the device type that you are configuring and click

Apply.

3Com recommends that you Auto Discover one device type at a time. See the online Help for detailed information about each field.

Auto Discovery Notes

■ If devices are on a different subnet from the Call Processor, enable IP

on the Call Processor (System-Wide Settings > IP Settings), and each device must have IP configuration information.

■ You can use DHCP to configure the telephones. You must configure

the DHCP server to provide the Call Processor IP address through option 184. Also, you can use the keypad to program IP settings into each device. See “

Configuring Option 184 on a Windows 2000 DHCP Server” on page 457 for DHCP information and “Using the Telephone Local User Interface Utility” on page 413 for telephone local

programming instructions.
