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.

This guide is designed to be your single source for information about your Netopia D-Series DSL DSU. It is
intended to be viewed on-line, using the powerful features of the Adobe Acrobat Reader. The information display
has been deliberately designed to present the maximum information in the minimum space on your screen. You
can keep this document open while you perform any of the procedures described, and find useful information
about the procedure you are performing.
If you prefer to work from hard copy rather than on-line documentation, you can also print out all of the manual,
or individual sections. The pages are formatted to print on standard 8 1/2 by 11 inch paper. We recommend
that you print on three-hole punched paper, so you can put the pages in a binder for future reference. For your
convenience, a printed copy can be purchased from Netopia. Order part number TED-DSU/Doc.
This guide is organized into chapters describing the Netopia D-Series’s advanced features. You may want to
read each chapter’s introductory section to familiarize yourself with the various features available.

IDSL connections.
Console port A DE-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 Netopia D-Series” on page 5-36.
Auxiliary port An HD-15 auxiliary port for attaching the V.35 interface cable to an external
Frame Relay router in DSU mode. In Filtering Bridge mode you can connect an
external modem to this port for remote out-of-band management. This
application requires separate purchase of the Async cable (Part TE6/DB25).
Crossover switch A crossover switch with Normal and Uplink positions. If you use Ethernet Port
#1 for a direct Ethernet connection between a computer and the Netopia
D-Series, set the switch to the Normal position. If you are connecting the
Netopia D-Series to an Ethernet hub, use Ethernet port #1 on the Netopia
D-Series and set the switch to the Uplink position.

The following table summarizes the meaning of the various LED states and colors:
8-port Ethernet hub Eight 10Base-T Ethernet jacks. You will use one of these to configure the
Netopia D-Series. 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 to any of the Ethernet ports on the Netopia D-Series, or
connect both your computer and the Netopia D-Series to an existing Ethernet
hub on your LAN.
