1 INTRODUCTION 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 Telephony3Com Networked Telephony Solutions merge telephony with networking 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.
20CHAPTER 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 System SoftwareThis section describes the major features of the NBX system. Auto AttendantWith 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 RelocationThe 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. Virtual Tie LinesYou 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 and Messaging FeaturesNBX 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 FeaturesNBX systems support the standard features, such as call park, conference, speed dial, and paging, that you expect in a business telephone system.
