The Netopia D-Series DSL DSUs are Digital Service Units or intelligent Ethernet ﬁltering bridges for SDSL or IDSL connections. They feature the ability to sense the connection type (Frame Relay or RFC 1483 DSL) and automatically conﬁgure themselves for use as a DSU to Ethernet bridge. In either conﬁguration the Netopia D-Series offers management features available locally or remotely, either in-band or out-of-band. The DSU mode offers a convenient way to migrate existing DDS or T1 service that uses an external CSU/DSU to connect to SDSL or IDSL. In the intelligent Ethernet bridge mode, the Netopia D-Series includes packet ﬁltering for enhanced security on the LAN and efﬁcient use of the DSL link.

■

The Netopia D7100 and D7171 use an SDSL link to a Copper Mountain DSLAM for the WAN connection. The Netopia D3100-I and D3232 use an ISDN Digital Subscriber Line (IDSL) to provide remote users

■

dedicated, digital access, even if they are connected to a central ofﬁce via a digital loop carrier (DLC) system or an ISDN repeater.

■

The Netopia D3232 and D7171 use DSL bonding technology, as available through Copper Mountain DSLAMs, to effectively double or quadruple the bandwidth of the DSL link.

In DSU mode the Auxiliary port functions as a Synchronous serial port supplying a V.35 DCE interface for connection to another router. In bridging mode the Ethernet hub bridges trafﬁc as a proxy for the MAC address supplied by the remote end of the DSL link.

The MAC address, or Media Access Control address is the physical address of a device connected to a network, expressed as a 48-bit hexadecimal number. Sometimes this is called the hardware address, and is a unique number assigned to each device by the manufacturer.

The Netopia D-Series provides an auto-sensing function that determines if the Auxiliary port or the hub is associated with the DSL connection. In either case you can manage the device via the hub using Telnet or SNMP, or via the serial console.

The hub effectively has two Ethernet MAC addresses in bridging mode: the proxied address that the remote end supplied and a local IP address for management purposes.

DSL Bonding, also called inverse multiplexing or IMUX, technology combines the bandwidth of multiple DSL (Digital Subscriber Line) circuits into a single virtual data pipe.

Before DSL Bonding was developed, the maximum speed of a DSL connection was dependent on the customer's distance from the central ofﬁce. DSL Bonding allows customers who are located at greater distances from the central ofﬁce to aggregate DSL circuits, in order to achieve two or more times the speed otherwise available to them with a single line.

The premise behind DSL Bonding is to provide a cost-effective means of bridging the bandwidth gap between relatively low network speeds and much higher rates, thereby allowing high-speed applications to use bandwidth up to 3 Mbps.

Netopia's DSL routers and DSUs with bonding allow users with 1.5 Mbps SDSL connections to enjoy speeds of over 3 Mbps, twice as fast as T1. They also allow customers who, because of line quality problems, were previously limited to a 144 Kbps IDSL connection, to enjoy speeds of up to 576 Kbps using four IDSL lines.

The Netopia D-Series DSL DSU can be used in either of two ways:

■ as an intelligent Ethernet ﬁltering bridge for DSL connections, or

■ as a Digital Service Unit

When the appropriate cables are connected, it senses the connection type (Frame Relay or ATM FUNI) and automatically conﬁgures itself for use as a DSU or a DSL to Ethernet bridge.

See the following sections for suggestions on how to connect the Netopia D-Series to different types of networks.

In bridge mode the Netopia D-Series performs a simple algorithm. When the Netopia D-Series receives a packet on the Ethernet hub, the packet is examined for its destination Media Access Control (MAC) address.

The MAC address is the physical address of a device connected to a network, expressed as a 48-bit hexadecimal number. Sometimes this is called the hardware address, and is a unique number assigned to each device by the manufacturer.

If the destination MAC address is the Netopia D-Series’s MAC address, based on its serial number, and it is for management purposes (Telnet or SNMP) or is an ICMP that needs response, it is accepted. If it is the MAC address that is being proxied (supplied by the DSLAM) it is encapsulated in ATM FUNI and transmitted over the DSL connection. A packet received from the DSL connection will be de-encapsulated and its MAC address examined. Either it is management trafﬁc for the Netopia D-Series, or it is encapsulated for Ethernet and transmitted over the hub.

DDDDSSSSUUUU mmmmooooddddee

The DSU behavior is similar, except that the datalink encapsulation on the WAN is Frame Relay, and the destination for packets from the WAN is the Auxiliary port. The Ethernet hub is only available for management (Telnet or SNMP).

A special male HD-15 to female V.35 cable supports the Netopia D-Series as a DCE connecting the Auxiliary port to a Frame Relay Access Device (FRAD) such as a sync serial router.

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

Application software

TCP/IP stack

Ethernet Driver

Your PC or Macintosh computer

To the Netopia D-Series

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 communicate using Internet protocols. TCP/IP stacks must be conﬁgured with some of the same information you used to conﬁgure the Netopia D-Series. 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 95 or 98 computers” on page 4-28. Macintosh computers use either MacTCP or Open Transport. See “Conﬁguring TCP/IP on Macintosh computers” on page 4-30.

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

EtherTalk and LocalTalk: These are AppleTalk protocols used over Ethernet. Once the Netopia D-Series 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.

Computers on your network must have TCP/IP installed and conﬁgured. This chapter tells you how to conﬁgure TCP/IP on the desktop computers on your network.

This chapter covers the following topics:

■ “Conﬁguring TCP/IP on Windows 95 or 98 computers” on page 28

■ “Conﬁguring TCP/IP on Macintosh computers” on page 30

Note: For information on conﬁguring TCP/IP on Windows 2000 or NT computers, please see the Microsoft documentation.

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

If you are manually conﬁguring for a ﬁxed or static IP address, perform 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 Properties screen (shown below), 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 Netopia D-Series with the Easy option in the SmartStart Wizard. Your ISP or network administrator may ask you to use a different IP address and subnet mask.

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

192.168.1.1. Click Add. This is the Netopia D-Series’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.
