INTRODUCTION

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

■ Network-based Telephony

■ Overview of the System Software

■ NBX NetSet Administration Utility

■ NBX NetSet Features

For information about installing 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 the telephone user, an NBX Telephone is a typical office telephone. You
can use it to make and receive calls, transfer calls, park calls, use voice
mail, and so on. Inside, the NBX Telephone is an Ethernet device that can
communicate over the LAN using Ethernet frames or, with the optional
upgrade, IP packets. The telephone also serves as an Ethernet switch or
hub (depending on the model of telephone) for your computer. You can
connect your computer network interface card (NIC) to your network
(LAN) through the telephone and avoid the need for a second LAN
connection at the desktop.

The core of 3Com Networked Telephony Solutions is the Network Call
Processor (NCP). The NCP 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.

20 CHAPTER 1: INTRODUCTION

The NBX system provides the reliability required in a business environment
because NBX system voice traffic is independent of computer traffic on
the same network. In fact, after the NCP completes the processing
required to connect two telephones, the telephones communicate
directly with each other. Therefore, existing conversations are not
affected if power to the NCP fails.

Overview of the

This section describes the major features of the NBX system.

System Software

Auto Attendant With the Auto Attendant, a full-featured call answering service, you set

up automated call answering, including multiple Auto Attendants, each
with separate menu structures, to manage incoming calls.

Auto Discovery and

Auto Relocation

Virtual Tie Lines You can connect two or more NBX systems that are connected to your

Integrated Voice Mail

and Messaging

Features

The Network Call Processor and the NBX Telephones communicate with
each other to streamline configuration. When you connect a new
telephone, the system discovers it and adds it to the configuration
database. The communication between devices means that if telephone
users move their telephones to a new location, the telephones retain their
extension number and personal settings. You do not have to change
telephone addresses and data for them.

Wide Area Network. Calls made over Virtual Tie Lines incur no toll
charges.

NBX Voice Messaging is a standard feature of the 3Com Networked
Telephony Solution. Voice Messaging supports Off-Site Notification,
which alerts you if you receive new voice messages when you are out of
the office. Voice Messaging also includes an IMAP (Internet Message
Access Protocol) mail server that allows you to retrieve voice mail
messages through any IMAP4-compatible e-mail client.

Standard NBX

Telephone Features

NBX systems support the standard features, such as call park, conference,
speed dial, and paging, that you expect in a business telephone system.

Overview of the System Software 21

Redialing From

Call Logs

In the NBX Business Telephone and NBX Basic Telephone display panels,
you can view logs of recent Missed Calls, Answered Calls, and Dialed
Calls. You can select and redial a call from any of these lists, as well as
from the directory of internal users, your personal speed dial list, or the
system-wide speed dial list.

Calling Line Identity

Restriction (CLIR)

When an NBX Telephone user makes a call on an ISDN channel, the
receiving party can see the identity of the caller (normal ISDN behavior).
When the NBX option Calling Line Identity Restriction (CLIR) is enabled,
the receiving party cannot see your identity when you call.

Computer Telephony

Integration (CTI)

Connectivity

3Com Networked Telephony Solutions provide a software-based CTI
solution through the Microsoft Telephony Applications Programming
Interface (TAPI). Your telephone and your computer connect to the same
LAN so that your computer does not need any special hardware, such as
proprietary cards. The NBX system works with TAPI 2.X-compliant CTI
applications.

Call Recording You can integrate a third-party call recording system into your NBX

system so that selected calls can be recorded. (Optional license required.)

NBX Call Reports NBX Call Reports, a Windows client program, is a standard feature of

3Com Networked Telephony Solutions. Call Reports allows you to save
calling data about inbound and outbound calls, present it in a report, or
export it to spreadsheets, word processors, or reporting programs.

NBX Resource

Pack CD

Support for Multiple

Languages

3Com Networked Telephony Solutions include the NBX Resource Pack CD
with the most recent system software for backup and upgrade purposes,
optional Microsoft Windows software from 3Com and third-party
vendors, and electronic versions of system documentation.

The NBX system’s Administrator Help is in English, by default, but the
User side of the NetSet administration utility’s Help system can be
configured for other languages. In addition, the three telephone Quick
Reference Cards, the NBX Telephone Guide, and the voice prompts are
available in multiple languages on the NBX Resource Pack CD.

22 CHAPTER 1: INTRODUCTION

NBX NetSet Administration Utility

The NBX NetSet Administration utility is an HTML-based web interface in
which you configure and manage the NBX system. You need Microsoft
Internet Explorer (version 5.5 or later is optimal) to administer the system.
(You do not need Internet access.)

Figure 1

when you log on to the NBX NetSet utility.

Figure 1 NBX NetSet - Main Menu Window

shows the NBX NetSet - Main Menu window, which appears

NBX systems present the NBX NetSet utility through an embedded web
server. NBX NetSet passwords grant system administrators and 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 speed dial lists and dial plan settings, and
upgrade the system software.

DIAL PLAN

The NBX system’s dial plan determines how the system handles calls.

28 CHAPTER 2: DIAL PLAN

Dial Plan Concepts and Overview

The dial plan configuration file is an ASCII text file that implements the
dial plan and specifies pretranslation (digit manipulation). The system is
shipped with several default dial plan configuration files, typically, a
3-digit and a 4-digit file for each supported country.

The dial plan configuration file includes several tables:

■ Internal — Must be table ID 1

■ Incoming — Must be table ID 2

■ Least Cost Routing — Must be table ID 3

■ Routes

■ Pretranslators

You can create additional tables if necessary.

Each dial plan table consists of a series of entries, each of which includes
a sequence of digits and the action to be performed by the NBX system in
response to sending or receiving those digits. For more information on
the Internal, Incoming, and Least Cost Routing dial plan tables, see “

Dial

Plan Tables” on page 34.

Usually, you access the dial plan configuration file and manage dial plan
operations, tables, pretranslators, and extension lists through the NBX
NetSet administration utility. If your dial plan is larger than 32,000
characters, however, you cannot edit the dial plan using the NBX NetSet
utility. You must export the dial plan, edit it, and then import it.

Before you configure the dial plan, please be sure that you understand
these concepts:

■ Call Process Flow (page 29)

■ Inbound and Outbound Call Processing (page 29)

■ NBX System Database (page 30)

■ NBX System Dial Plan (page 30)

■ Pretranslation (page 31)

■ Routing (page 31)

In addition, be sure to understand how the dial plan configuration file
can affect other parts of the NBX system. See “

System Features Affected

by the Dial Plan Configuration” on page 32.

Dial Plan Concepts and Overview 29

Call Process Flow The dial plan configuration file is a key component of inbound and

outbound call processing. The dial plan tables in the configuration file
process incoming calls in this order:

1 Incoming Dial Plan Table
2 Pretranslator Table

The dial plan tables process outgoing calls in this order:

1 Internal Dial Plan Table
2 Least Cost Routing Table

After pretranslation (if performed), the final translation process routes the
call to the destination.

Inbound and

Outbound Call

Processing

The system routes all inbound and outbound calls through the dial plan.

Inbound Call Processing

The system processes inbound calls using the Incoming table. The system
can also use pretranslators to perform digit manipulations on incoming
calls before it uses the Incoming table.

Each pretranslator operation performs a digit manipulation operation on
the dialed digits. For incoming calls, if the DID/DDI range matches the
internal extensions, the dial plan requires no pretranslator. However, you
can use pretranslators to map nonmatching dialed numbers on an
incoming DID/DDI channel to desired internal extensions. See the
example in Customer Requirement 1 in “

Sample Solutions Using Dial Plan

Configuration File Commands” on page 116.

Outbound Call Processing

The system processes outbound calls using the Internal dial plan table or
the Least Cost Routing table.

You can add entries to the Internal dial plan table to match the system to
your service. See Customer Requirement 2 in “

Sample Solutions Using

Dial Plan Configuration File Commands” on page 116.

If you have entries in both the Least Cost table and the Internal table for
the same purpose, the behavior of the dial plan can be confusing. 3Com
recommends that you accomplish least cost routing using Internal Table

entries. For more information, see TimedRoute Create, TimedRouteEntry

Create, and TimedRouteOperation Create later in this chapter.

NBX System Database The NBX system database contains a default dial plan that is initially

loaded at the factory and is reloaded if you purge the database. The
default dial plan for the SuperStack 3 NBX system is a 4-digit plan; for the
NBX 100, it is a 3-digit plan.

Changes that you make to any system settings, including changes made
by importing a modified dial plan configuration file, are reflected in the
database. When you reboot the system, it loads the database with any
changes that you have made.

The NBX system database includes all of the settings necessary for system
operation:

■ IP and MAC addresses for the Network Call Processor, telephones, and

line cards

■ Auto Attendant definitions and menus

■ Dial plan configuration file information

■ Voice mail settings and messages

■ Telephone extensions

■ Hardware configuration information

■ Button mappings for NBX and third-party telephones

■ Call group definitions

■ Software license information

■ User profiles

NBX System Dial Plan You can import a dial plan configuration file to provide the system with a

set of operating instructions for managing the telephone system.
Alternatively, if you have made changes to the currently loaded
instructions through the NBX NetSet utility, you can export the dial plan
configuration file to save it. You can also make changes by editing the
configuration file off-system, using any ASCII editor, and then importing
the modified file. You can easily reuse a given configuration file on many
systems. For more information, see “

Importing and Exporting Dial Plan

Configuration Files” on page 45.
