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 services 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 4753 G.SHDSL Integrated Access Device is that device: a Centrex-based PBX system combined with an SHDSL internet router.

The Netopia 4753 G.SHDSL 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.

G.SHDSL.

provided by the telephone company. G.SHDSL negotiates the highest achievable data rate given the loop conditions and will allow you to connect to the Internet at a minimum of 128Kbps bi-directional, up to 2.320 Mbps. Your LAN will constantly be connected and you will not have to dial into the Internet. G.SHDSL uses more of the bandwidth on copper phone lines than what is currently used for plain old telephone ser vice (POTS). By using frequencies between 26 kHz and 1MHz, G.SHDSL can encode more data to achieve higher data rates than would otherwise be possible in the restricted frequency range of a POTS network (up to 4 kHz). In order to use the frequencies above the voice audio spectrum, DSL equipment must be installed on both ends.

Finding an Internet Service Provider

The Netopia 4753 G.SHDSL Integrated Access Device provides its high speed symmetric (two-way) digital connection to the Internet through a Competitive Local Exchange Carrier (CLEC) -- 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 4753 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 G.SHDSL 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 ser vices.

Use an ISP that provides Internet access through a G.SHDSL Digital Subscriber Line and that suppor ts the Netopia 4753 G.SHDSL 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 4753, 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.

Unique requirements

Make sure the ISP can meet any unique requirements you may have, such as:

■

Dynamic or static IP addressing

Class C IP address

■

Custom domain name

■

Multiple e-mail addresses

Web site hosting

■

Pricing and support

Compare pricing, service, and technical suppor t ser vice among various ISPs.

Endorsements

Consider recommendations from colleagues and reviews in publications. Netopia lists Netopia Cer tiﬁed ISPs on our Web site at

http://www.netopia.com

Deciding on an ISP Account

Your ISP may offer various Internet access account plans. Typically, these plans vary by usage charges and the number of host IP addresses supplied. Evaluate your networking needs and discuss them with your ISP before deciding on a plan for your network.

Setting Up Internet Services 2-3

Setting up a Netopia 4753 account

Check whether your ISP has the Netopia 4753 on its list of supported products that have been tested with a particular conﬁguration. If the ISP does not have the Netopia 4753 on such a list, describe the Netopia 4753 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.

Obtaining an IP address

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 4753.

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.

SmartIP

The Netopia 4753 G.SHDSL Integrated Access Device supports Multiple Network Address Translation (MultiNAT).

Network Address Translation provides Internet access to the network connected to the Netopia 4753 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.

For more information on Network Address Translation, see Chapter 11, “Multiple Network Address Translation.”

Obtaining Information from the ISP

After your account is set up, the ISP should send you the IP parameter information that will help you conﬁgure the Netopia 4753.

Local LAN IP address information to obtain

Your ISP will need to provide you with the following information:

The default gateway IP address (same as remote IP address in most cases)

■

Local WAN IP address and subnet mask

■

Primary and secondary domain name ser ver (DNS) IP addresses

Domain name (usually the same as the ISP’s domain name unless you have registered for your own

■

individual domain name)

Note:

The default gateway, WAN address and mask, DNS, and domain name are all obtainable via WAN DHCP, if your ISP supports it.

With Network Address Translation

If you are using MultiNAT, you should obtain the following:

If you are connecting to a remote site using Network Address Translation on your router, your provider will

■

2-4 Administration Guide

not deﬁne the IP address information on your local LAN. You can deﬁne this information based on an IP conﬁguration that may already be in place for the existing network. Alternatively, you can use the default IP address range used by the router.

Without Network Address Translation

If you are not using Network Address Translation, you will need to obtain all of the local LAN IP address information from your ISP.

If you are not using SmartIP (NAT), you should obtain:

The number of Ethernet IP host addresses available with your account and the ﬁrst usable IP host address

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 4753. 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 Proper ties 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.

Click on the Gateway tab, and if there is an installed gateway, remove it.

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 4753.

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

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 4753’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 4753 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 4753 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 4753.

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