The Netopia 4741 Voice/Data Integrated Access Devices (IADs) make it possible for small businesses to take advantage of the advanced communications technologies previously limited to larger organizations. By integrating multiple voice connections and high-speed Internet access on one DSL line, businesses can squeeze the most out of their communications budget.

The Netopia 4741 ADSL Integrated Access Device combines a complete telephone system with a business-class data router to deliver a customized package of business communications services over DSL. The Netopia 4741 supports the broad array of phone features offered through your service provider and uses your existing analog telephone equipment. The Netopia 4741 includes Netopia's sophisticated data routing engine optimized for small and medium size business needs. These business-class features include IP routing, ﬁrewall, NAT, MultiNAT, DHCP and both PPTP and IPSec VPN functionality.

This section covers the following topics:

Small- to medium-sized businesses need two kinds of services: Internet presence and voice telephony. But they don't need the additional burden of maintaining switching equipment or administering IP and voice services for their ofﬁces. An Integrated Access Device (IAD) that offers high-speed DSL for IP connectivity and a voice telephone system that somebody else (the phone company) administers is the simple solution.

At the phone company's central ofﬁce, where all the big switch gear is, there are two kinds of switches for the two kinds of services, voice and data. The IAD must be capable of communicating with a wide array of possible combinations of voice and data switches.

An IAD combines the voice telephony features of a telephone system with the data routing features of an IP data router. The device uses a single outside line connection to carry all voice and data transmissions. If the device uses a DSL interface, it can carry all of these services over a single existing copper telephone line by regulating the ﬂow of voice and data packets on the copper wire for voice and data trafﬁc.

The Netopia 4741 ADSL Integrated Access Device is that device: a Centrex-based system combined with an ADSL internet router.

The Netopia 4741 ADSL Integrated Access Device provides the following features:

Support for ordinary analog phone equipment.

that small businesses use today. No expensive handsets to order, no new interface to learn.

Conﬁguring TCP/IP on Macintosh Computers

The following is a quick guide to conﬁguring TCP/IP for MacOS computers. Conﬁguring TCP/IP in a Macintosh computer requires the following:

■ You must have either Open Transport or Classic Networking (MacTCP) installed.

Note: If you want to use the Dynamic Host Conﬁguration Protocol (DHCP) server built into your Netopia 4741 to assign IP addresses to your Macintoshes, you must be running Open Transport, standard in MacOS 8 and optional in earlier system versions. You can have your Netopia 4741 dynamically assign IP addresses using MacTCP; however, to do so requires that the optional AppleTalk kit be installed which can only be done after the router is conﬁgured.

■ You must have built-in Ethernet or a third-party Ethernet card and its associated drivers installed in your

Macintosh.

Dynamic conﬁguration (recommended)

The Dynamic Host Conﬁguration Protocol (DHCP), which enables dynamic addressing, is enabled by default in the router. To conﬁgure your Macintosh computer for dynamic addressing do the following:

1. Go to the Apple menu. Select Control Panels and then TCP/IP.

2. With the TCP/IP window open, go to the Edit menu and select User Mode. Choose Basic and click OK.

3. In the TCP/IP window, select “Connect via: Ethernet” and “Conﬁgure: Using DHCP Server.”

Note: You can also use these instructions to conﬁgure other computers on your network to accept IP addresses served by the Netopia 4741.

3-6 Administration Guide

Static conﬁguration (optional)

If you are manually conﬁguring for a ﬁxed or static IP address, perform the following:

1. Go to the Apple menu. Select Control Panels and then TCP/IP or MacTCP.

2. With the TCP/IP window open, go to the Edit menu and select User Mode. Choose Advanced and click OK.

Or, in the MacTCP window, select Ethernet and click the More button.

3. In the TCP/IP window or in the MacTCP/More window, select or type information into the ﬁelds as shown in the following table.

Connect via: Ethernet Conﬁgure: Manually IP Address: 192.168.1.2 Subnet mask: 255.255.255.0, or for 12-user models

255.255.255.240 Router or Gateway address: 192.168.1.1 Name server address: Enter the primary and secondary name server

addresses given to you by your ISP

Implicit Search Path: Starting domain name:

Enter your domain name; if you do not have a domain name, enter the domain name of your ISP

4. Close the TCP/IP or MacTCP control panel and save the settings.

5. If you are using MacTCP, you must restart the computer. If you are using Open Transport, you do not need to restart.

Sharing the Connection 3-7

Note: You can also use these instructions to conﬁgure other computers on your network with manual or static IP addresses. Be sure each computer on your network has its own IP address.

This chapter describes how to physically connect the Netopia 4741 to your local area network (LAN). Before you proceed, make sure the Netopia 4741 is properly conﬁgured. You can customize the device’s conﬁguration for your particular LAN requirements using console-based management (see “Console-Based Management” on

page 5-1).

Readying Computers on Your Local Network

PC and Macintosh computers must have certain components installed before they can communicate through the Netopia 4741. The following illustration shows the minimal requirements for a typical PC or Macintosh computer.

Application software

TCP/IP stack

Ethernet

Your PC or Macintosh computer

To the Netopia 4741

Application software: This is the software you use to send e-mail, browse the World Wide Web, read newsgroups, etc. These applications may require some conﬁguration. Examples include the Eudora e-mail client and the Web browsers Microsoft Internet Explorer and Netscape Navigator.

TCP/IP stack: This is the software that lets your PC or Macintosh computer communicate using Internet protocols. TCP/IP stacks must be conﬁgured with some of the same information you used to conﬁgure the Netopia 4741. There are a number of TCP/IP stacks available for PC computers. Windows 95 includes a built-in TCP/IP stack. See “Conﬁguring TCP/IP on Windows-based Computers” on page 3-2. Macintosh computers use either MacTCP or Open Transport. See “Conﬁguring TCP/IP on Macintosh Computers” on page 3-5.

Ethernet: Ethernet hardware and software drivers enable your PC or Macintosh computer to communicate on the LAN.

Once the Netopia 4741 is properly conﬁgured and connected to your LAN, PC and Macintosh computers that have their required components in place will be able to connect to the Internet or other remote IP networks.
