INTRODUCTION

1

The NBX Administrator’s Guide provides information and instructions for configuring 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 the hardware components, see the

NBX Installation Guide.

Network-based	3Com Networked Telephony Solutions merge telephony with networking
Telephony	by delivering business telephone service over a data network.
	To the telephone user, the NBX Business Telephone or NBX Basic
	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. You can
	also dial speed dial numbers from either telephone model. Inside the NBX
	Telephone is an Ethernet device that can communicate over the LAN
	using Ethernet frames or, optionally, IP packets (with the optional
	upgrade). 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 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.

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 Call Processor 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 Call Processor fails or if the network operating system crashes or hangs.

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 The Call Processor and the NBX Telephones communicate with each other Auto Relocation 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.

Virtual Tie Lines You can connect two or more NBX systems that are connected to your Wide Area Network. Calls made over Virtual Tie Lines incur no toll charges.

Integrated Voice Mail NBX Voice Messaging is a standard feature of the 3Com Networked and Messaging Telephony Solution. Voice Messaging supports Off-Site Notification,

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

Overview of the System Software

21

Redialing From In the NBX Business Telephone and NBX Basic Telephone display panels, Call Logs 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 When an NBX Telephone user makes a call on an ISDN channel, the Restriction (CLIR) 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 3Com Networked Telephony Solutions provide a software-based CTI Integration (CTI) solution through the Microsoft Telephony Applications Programming

Connectivity 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 3Com Networked Telephony Solutions include the NBX Resource Pack CD 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.

Support for Multiple The NBX system’s Administrator Help is in English, by default, but the Languages User side of the NetSet administration utility’s Help system can be

configured for several 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	The NBX NetSet Administration utility is an HTML-based web interface in
Administration	which you configure and manage the NBX system. You need a web
Utility	browser, such as Microsoft Internet Explorer, to administer the system.
	Internet Explorer version 5.5 is optimal. (You do not need Internet access.)
	Figure 1 shows the NBX NetSet - Main Menu window, which appears
	when you log on to the NBX NetSet utility.
	Figure 1 NBX NetSet - Main Menu Window

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.

26 CHAPTER 1: INTRODUCTION

DIAL PLAN

2

The NBX system’s dial plan determines how the system handles calls. It defines the set of destinations that the system can reach, how to get to these destinations, and which telephone numbers to dial to reach these destinations. This chapter provides information about understanding, developing, and managing the dial plan. It covers these topics:

28 CHAPTER 2: DIAL PLAN

Dial Plan Concepts The dial plan configuration file is an ASCII text file that implements the and Overview 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” later in this chapter.

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

■Inbound and Outbound Call Processing

■NBX System Database

■NBX System Dial Plan

■Pretranslation

■Routing

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” later in this chapter.

Dial Plan Concepts and Overview

29

Call Process Flow

Inbound and

Outbound Call

Processing

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:

1Incoming Dial Plan Table

2Pretranslator Table

The dial plan tables process outgoing calls in this order:

1Internal Dial Plan Table

2Least Cost Routing Table

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

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” later in this chapter.

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” later in this chapter.

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.

30 CHAPTER 2: DIAL PLAN

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 the NBX 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 quickly and easily reuse a given configuration file on many systems. For more information, see “Importing and Exporting Dial Plan Configuration Files” later in this chapter.

The system is shipped with several default dial plan configuration files, typically, a 3-digit and a 4-digit file for each country that is supported. In addition, the file samples.txt contains several examples that illustrate how you can configure the dial plan configuration file to control how the system manages incoming and outgoing calls.
