Ofﬁce telephone systems are commonly one of two types, PBX (Private Branch Exchange) or Centrex (Central Ofﬁce Exchange). Technically, Centrex is a subset of PBX.

PBX users share a certain number of outside lines for making telephone calls external to the PBX. Most medium-sized and larger companies use a PBX because it's much less expensive than connecting an external telephone line to every telephone in the organization. In addition, it's easier to call someone within a PBX because the number you need to dial is typically just 3 or 4 digits.

Centrex is a newer variation on the PBX. It is a PBX with all switching occurring at a local telephone of ﬁce instead of at the company's premises. Typically, the telephone company owns and manages all the communications equipment necessary to implement the PBX and then sells various services to the company.

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 Symmetric (same speed upload and download) DSL for IP connectivity and a PBX 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 voice switch is called a Voice Gateway and the data switch is called a Digital Subscriber Line Access Multiplexer (DSLAM) or access concentrator. Both the voice and data signals are concentrated at the DSLAM and forwarded either to a data router or to the Voice Gateway. Both kinds of switches are manufactured by a variety of companies. The IAD must be capable of communicating with a wide array of possible combinations of Voice Gateways and DSLAMs.

1-2 Administration Guide

An IAD combines the voice telephony features of a telephone PBX 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 carr y all of these ser vices over a single existing copper telephone line by using the different frequency ranges available on the copper wire for voice and data trafﬁc.

The Netopia 4752 SDSL Integrated Access Device is that device: a Centrex-based PBX system combined with an SDSL internet router.

The Netopia 4752 SDSL Integrated Access Device provides the following features:

Support for ordinary analog phone equipment.

Works with the same FXS analog phone sets and key systems

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

Centrex support.

Advanced telephone features enabled by your service provider's telephone switch such as

call forwarding or conferencing operate exactly as they did before.

Netopia data routing engine.

Provides the same advanced, business-class data routing features used by leading DSL service providers around the world. Includes advanced data functionality such as ﬁrewall, VPN client and server (including PPTP and IPSec), DHCP automated address assignment, and Network Address Translation (NAT and MultiNAT).

Physical features include:

SDSL WAN Interface interoperable with major ATM- and Frame Relay-based DSL equipment.

■

A 10/100 Ethernet LAN Port.

■

Eight analog telephone ports (local extensions).

One DB-9 serial console port.

■

Front panel status lights.

■

Setup and conﬁguration management via console menu.

Note:

Some companies act as their own ISP. For example, some organizations have branch of ﬁces that can use the Netopia 4752 to access the Internet via the main ofﬁce in a point-to-point scenario. If you install the Netopia 4752 in this type of environment, refer to the following sections for speciﬁc information you must receive from the network administrator to conﬁgure the Netopia 4752 properly.

The Netopia 4752 SDSL Integrated Access Device provides its high speed symmetric (two-way) digital connection to the Internet through a Local Exchange Carrier (LEC) -- a type of mini phone company. The CLEC uses a compatible type of switching equipment known as a Digital Subscriber Line Access Multiplexer (DSLAM). The DSLAM that you connect to with your Netopia Router must be capable of handling these symmetric connections. The Netopia 4752 is certiﬁed for use with DSLAMs manufactured by Nokia , Lucent, Paradyne, Nortel networks, and Copper Mountain.

If you have purchased your Netopia Router through a Netopia ISP par tner, you can be sure that an account that supports SDSL connections will be available.

If your area has more than one ISP, the following considerations will help you decide which ISP is best suited for your requirements.

In determining which Internet ser vice provider (ISP) to establish your account with, make sure that your ISP supports connections via a CLEC that also supports voice services.

Use an ISP that provides Internet access through a Symmetric Digital Subscriber Line (SDSL) and that suppor ts the Netopia 4752 SDSL Integrated Access Device. If you would like to use an ISP that you already have a relationship with but that is not familiar with the Netopia 4752, call us at 1-800-NETOPIA. Our representative can call your ISP and introduce them to the product. If necessar y, we will provide them with the technical background they need to support the product.

Check whether your ISP has the Netopia 4752 on its list of supported products that have been tested with a particular conﬁguration. If the ISP does not have the Netopia 4752 on such a list, describe the Netopia 4752 in as much detail as needed, so your ISP account can be optimized. As appropriate, refer your ISP to Netopia’s Web site www.netopia.com for more information.

Typically, each network computer that requires Internet access requires its own unique IP address. If some or all network computers require simultaneous Internet access, obtain a block of IP host addresses large enough for each computer to have its own address, plus one for the Netopia 4752.

Consider expected growth in your network when deciding on the number of addresses to obtain. Alternatively, you can use the Network Address Translation feature of SmartIP.

SSSSmmmmaaaarrrrttttIIIIPP

The Netopia 4752 SDSL Integrated Access Device supports Multiple Network Address Translation (MultiNAT).

Network Address Translation provides Internet access to the network connected to the Netopia 4752 using only a single IP address. These routers translate between the internal or local area network (LAN) addresses and a single external IP address, and route accordingly. MultiNAT is a means of mapping one or more IP addresses and/or IP service ports into different values. This

4752. For a new installation, use the Ethernet connection. Alternatively, you can use the console connection to run console-based management using a direct serial connection. You can either connect your computer directly the Ethernet port using a crossover cable, or connect both your computer and the Netopia 4752 to an existing Ethernet hub on your LAN.

Console port A DB-9 console port for a direct serial connection to the console screens. You

can use this if you are an experienced user. See “Connecting a Console Cable

to Your Device” on page 6-3.

Power port A mini-DIN8 power adapter cable connection.

1. Connect the mini-DIN8 connector from the power adapter to the power port, and plug the other end into an

electrical outlet.

2. Connect one end of the RJ-45 cable to the DSL port, and the other end to your DSL wall outlet.

3. Connect the Ethernet cable to the Ethernet por t on the unit and the other end to your Ethernet hub.

You should now have: the power adapter plugged in; the Ethernet cable connected between the router and your Ethernet hub; and the DSL cable connected between the router and the DSL wall outlet.

Once you have set up your physical local area network, you will need to conﬁgure the TCP/IP stack on each client workstation connected to your Netopia 4752. This chapter describes how to conﬁgure TCP/IP for both Windows-based and Macintosh computers.

This chapter explains the following topics:

■ “Conﬁguring TCP/IP on Windows-based Computers” on page 4-2

■ “Conﬁguring TCP/IP on Macintosh Computers” on page 4-5

4-2 Administration Guide

Conﬁguring TCP/IP on Windows-based Computers

Conﬁguring TCP/IP on a Windows computer requires the following:

■ An Ethernet card (also known as a network adapter)

■ The TCP/IP protocol must be “bound” to the adapter or card

Dynamic conﬁguration (recommended)

To conﬁgure your PC for dynamic addressing do the following:

1. Go to the Start Menu/Settings/Control Panels and double click the Network icon. From the Network components list, select the Conﬁguration tab.

2. Select TCP/IP-->Your Network Card. Then select

Properties. In the TCP/IP Properties screen, select the IP Address tab. Click “Obtain an IP Address automatically”.

3. Click on the DNS Conﬁguration tab. Click Disable DNS. DNS will be assigned by the router with DHCP.

4. Click OK in this window and the next window. When prompted, reboot the computer.

Note: You can also use these instructions to conﬁgure other computers on your network to accept IP addresses served by the Netopia 4752.

Sharing the Connection 4-3

Static conﬁguration (optional)

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

1. Go to Start Menu/Settings/Control Panels and double click the Network icon. From the Network components list, select the Conﬁguration tab.

2. Select TCP/IP-->Your Network Card. Then select Properties. In the TCP/IP Proper ties screen, select the IP Address tab. Click “Specify an IP Address.”

Enter the following:

IP Address: 192.168.1.2 Subnet Mask: 255.255.255.0, or for 12-user models 255.255.255.240

This address is an example of one that can be used to conﬁgure the router. Your ISP or network administrator may ask you to use a different IP address and subnet mask.

4-4 Administration Guide

3. Click on the Gateway tab (shown below). Under “New gateway,” enter

192.168.1.1. Click Add. This is the Netopia 4752’s pre-assigned IP address.

4. Click OK in this window and the next window. When prompted, reboot the computer.

Click on the DNS Conﬁguration tab. Click Enable DNS. Enter the following information:

Host: Type the name you want to give to this computer.

Domain: Type your domain name. If you don't have a domain name, type your ISP's domain name; for example, netopia.com.

DNS Server Search Order: Type the

primary DNS IP address given to you by your ISP. Click

Add. Repeat this process for the secondary DNS.

Domain Sufﬁx Search Order: Enter the same domain

name you entered above.

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.

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 4752 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 4752 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-par ty 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 4752.

4-6 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.

Option: Select/Type:

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 primar y and secondar y name ser ver

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 restar t the computer. If you are using Open Transport, you do not need to restart.

Sharing the Connection 4-7

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.

More information about conﬁguring your Macintosh computer for TCP/IP connectivity through a Netopia 4752 can be found in Technote NIR_026, “Open Transport and Netopia Routers,” located on the Netopia Web site.
