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 one of the RJ-11 cables to the “Telco 1" port, and the other end to one of your wall outlets.
Making the Physical Connections 2-3
If you have two phone lines on a single wall outlet, this is the only T elco connection you need to make. The pinout configuration for the lines on the Telco 1 port is shown in the following diagram:
1234
5678
Telco 1
Telco 2
Your first Telco number is carried on the inner pair and the second number on the outer pair.
3. If you have a second phone line with its own separate wall outlet, and want to use both built-in modems, connect one end of one of the RJ-11 cables to the “Telco 2" port, and the other end to your second wall outlet.
4. Connect the Ethernet cable to any of the Ethernet ports on the router. (If you are connecting the router to an existing Ethernet hub, use Ethernet port #1 on the router and set the
crossover switch to the Uplink position.) You should now have: the power adapter plugged in; the Ethernet cable connected between the router and
your computer; and the telephone cables connected between the router and the wall outlets.
5. Insert your Netopia CD and follow the instructions to install an Internet browser and the Adobe Acrobat Reader, if you don’t already have them.
6. Now, run the SmartStart application. SmartStart requires the following:
your computer must be Ethernet-capable, that is it must have both an Ethernet card and TCP/IP stack
software. See “Before running SmartStart” on page 3-1.
your computer and the Netopia R2121 are powered ON.
the computer running SmartStart and the Netopia R2121 to be configured must be on the same Ether-
net segment; there can be no intervening routers. Repeaters, such as 10Base-T hubs, are acceptable.
Go to the section “Setting up your Router with the SmartStart Wizard” on page 3-3 for details on running SmartStart.

Once you’ve connected your router to your computer and your telecommunications line and installed a web browser, you’re ready to run the Netopia SmartStart™ Wizard. The SmartStart Wizard will help you set up the router and share the connection. The SmartStart Wizard walks you through a series of questions and based on your responses automatically configures the router for connecting your LAN to the Internet or to your remote corporate network.
The SmartStart Wizard will:
automatically check your Windows 95, 98, or NT PC’s TCP/IP configuration to be sure you can accept a
dynamically assigned IP address, and change it for you if it is not set for dynamic addressing
check the physical connection from your computer to your router without your having to enter an IP address
assign an IP address to your router
allow you to register with a new ISP if you don’t already have one (for analog modem and ISDN models).
For a list of ISPs that support Netopia Routers in North America, see the Netopia website at http://www.netopia.com.

Notes:
The computer running SmartStart must be on the same Ethernet cable segment as the Netopia R2121.
Repeaters, such as 10Base-T hubs between your computer and the Netopia R2121, are acceptable, but devices such as switches or other routers are not.
• SmartStart for the PC will set your TCP/IP control panel to “Obtain an IP address automatically” if it is not already set this way. This will cause your computer to reboot. If you have a specified IP address configured in the computer, you should make a note of it before running SmartStart, in case you do not want to use the dynamic addressing features built in to the Netopia Router and need to restore the fixed IP address.
Setting up your Router with the SmartStart Wizard 3-3

Setting up your Router with the SmartStart Wizard

The SmartStart Wizard is tailored for your platform, but it works the same way on either a PC or a Macintosh. Insert the Netopia CD, and in the desktop navigation screen that appears, launch the SmartStart Wizard application.
SmartStart Wizard configuration screens
The screens described in this section are the default screens shipped on the Netopia CD. They derive from two initialization (.ini) files included in the same directory as the SmartStart application file. Your reseller or your ISP may have supplied you with customized versions of these files.
If you have received a CD or diskette that has been customized by your reseller or ISP , you
can run the SmartStart Wizard directly from the CD or diskette and follow the instructions your reseller or ISP provides. This makes your Netopia R2121 configuration even easier.
If you have received only the .ini files from your reseller or ISP, perform the following:
Copy the entire directory folder containing the SmartStart Wizard application from the
Netopia CD to your hard disk.
Copy the customized .ini files to the same directory folder that contains the Smart-
Start Wizard application, allowing the copy process to overwrite the original .ini files.
Run the SmartStart Wizard from your hard disk. You can then follow the instructions
your reseller or ISP provides.
The SmartStart Wizard presents a series of screens to guide you through the preliminary configuration of a Netopia R2121. It will then create a connection profile using the information you supply to it.
Welcome screen. The first screen welcomes you to the SmartStart Wizard configuration utility.
Click the Next button after you have responded to the interactive prompts in each screen.
The Help button will display useful information to assist you in responding to the interactive prompts.

When the test succeeds, SmartStart indicates success. If the test fails, the wizard displays an error screen. If the test fails, check the following:
Check your cable connections. Be sure you have connected the router and the computer properly, using the
correct cables. Refer to the Step 1 “Connect the Router” sheet in your Netopia R2121 documentation folio.
Make sure the router is turned on and that there is an Ethernet connection between your computer and the
router.
Check the TCP/IP control panel settings to be sure that automatic IP Addressing (Windows) or DHCP
(Macintosh) is selected. If you are using a Windows PC, SmartStart will automatically detect a static IP address and offer to configure the computer for automatic addressing. On a Macintosh computer, you must manually set the TCP/IP Control Panel to DHCP. See “Configuring TCP/IP on Macintosh computers” on
page 3-13. If you currently use a static IP address outside the 192.168.1.x network, and want to continue
using it, use the Advanced option to assign the router an IP address in your target IP range. See “Advanced
option” on page 3-8.
If all of the above steps fail to resolve the problem, reset the router to its factory default settings and rerun
SmartStart.

SmartView overview

SmartView is a Java-based applet that runs in a web browser window. It intermittently polls the Router for information to monitor the Router’s state and control connection and disconnection of Connection Profiles. SmartView should run under any Java Virtual Machine (JVM)-enabled browser, and is therefore platform independent.
Note: The SmartView applet will only run under Java-enabled browsers. Be sure that the browser you are using is at least Microsoft Internet Explorer Version 3.0 or higher, or Netscape Navigator Version 3.0 or Communicator Version 4.0 or higher. If your browser does not meet this requirement, you can upgrade with a browser supplied on the Netopia CD.
Using SmartView, you can view your Router’s:

Event History pages

The Netopia R2121 records certain relevant occurrences in event histories. Event histories are useful for diagnosing problems because they list what happened before, during, and after a problem occurs. You can view two different event histories: one for the router’s system and one for the WAN. The Netopia R2121’s built-in battery backup prevents loss of event history from a shut down or reset.
The Router’s event histories are structured to display the most recent events first, and to make it easy to distinguish error messages from informational messages. Error messages are prefixed with an asterisk. Both the WAN Event History and the Device Event History retain records of up to 128 of the most recent events. Y ou can refresh the Event history logs by clicking the Update button.

Connecting through a Telnet session

Features of the Netopia R2121 may be configured through the console screens. Before you can access the console screens through Telnet, you must have:
a network connection locally to the router or IP access to the router through the WAN port. This could be
the same connection as the one you used with SmartStart. Note: Alternatively, you can have a direct serial console cable connection using the provided console cable
for your platform (PC or Macintosh) and the “Console” port on the back of the router. For more information on attaching the console cable, see “Connecting a local terminal console cable to your router” on
page 6-3.
Telnet software installed on the computer you will use to configure the router
Console-based Management 6-3
Configuring Telnet software
If you are configuring your router using a Telnet session, your computer must be running a Telnet software program.
If you connect a PC with Microsoft Windows, you can use a Windows Telnet application or simply run Telnet
from the Start menu.
If you connect a Macintosh computer, you can use the NCSA Telnet program supplied on the Netopia
R2121 CD. You install NCSA Telnet by simply dragging the application from the CD to your hard disk.

Connecting a local terminal console cable to your router

You can perform all of the System Configuration activities for your Netopia R2121 through a local serial console connection using terminal emulation software, such as HyperTerminal provided with Windows95 on the PC, or ZTerm, included on the Netopia CD, for the Macintosh.
The Netopia R2121 back panel has a connector labeled “Console” for attaching the Router to either a PC or Macintosh computer via the serial port on the computer. (On a Macintosh, the serial port is called the Modem port or the Printer port.) This connection lets you use the computer to configure and monitor the Netopia R2121 via the console screens.

The Easy Setup Profile screen is where you configure the parameters that control the Netopia R2121’s connection to a specific remote destination, usually an ISP or a corporate site.
On a Netopia R2121 Dual Analog Router you can add up to 15 more connection profiles, for a total of 16. See
“Creating a new Connection Profile” on page 8-2.
1. Select Number to Dial and enter the telephone number you received from your ISP. This is the number the Netopia R2121 dials to reach your ISP. Enter the number as you would dial it, including any required prefixes (such as area, access, and long-distance dialing codes).
Note: When placing a multi-channel call, the answering equipment must either:
be in a “hunt group,” where a single telephone number services multiple lines, or
the answering side must implement MP or BAP as a method to advise the calling side what number(s)
to use.
ISPs or corporate IS groups will meet these conditions. For other non-standard dialup connections, you should verify that one or the other of these conditions is true.
2. To enable address translation, toggle Address Translation Enabled to Yes. For more information on Network Address Translation, see “IP Setup, SmartIP and Network Address Translation” on page 10-1.
3. Select Local WAN IP Address and enter the local WAN address your ISP gave you.
7-4 User’s Reference Guide
The default address is 0.0.0.0, which allows for dynamic addressing, when your ISP assigns an address each time you connect. However, you may enter another address if you want to use static addressing.
When using numbered interfaces, the Netopia Router will use its local WAN IP address and subnet
mask to send packets to the remote router. Both routers have WAN IP addresses and subnet masks associated with the connection.
When using unnumbered interfaces, the Netopia Router will use either its local Ethernet IP address or
its NAT address (if so configured) and subnet mask to send packets to the remote router. Neither router has a WAN IP address or subnet mask associated with this connection.
Note: If your ISP has not given you their IP or subnet mask addresses, then you may enter an IP address such as 127.0.0.2, and an IP subnet mask such as 255.0.0.0. With these settings the router will get this information dynamically when it connects to the remote site.
4. If your ISP uses unnumbered (system-based routing), select Remote IP Address and enter the IP address your ISP gave you.
Then select Remote IP Mask and enter the IP subnet mask of the remote site you will connect to.
5. Select the PPP Authentication pop-up menu and choose the type of connection security your ISP told you to use (PAP, CHAP , P AP-TOKEN, or CACHE-TOKEN). If you choose any of these authentication methods, go to the next step. If your ISP does not use any of these authentication methods, choose None and skip to the last step. When you create a connection profile from Easy Setup, the default setting is PAP.
6. If your ISP uses PAP or PAP-TOKEN, select Send User Name and enter the user name your ISP gave you to connect. If you selected PAP, select Send Password and enter your password. If you selected PAP-TOKEN, you don’t enter the password now. Your name and password can be up to 32 characters each.
If your ISP uses CHAP , select Send Host Name and enter the user name your ISP gave you to connect. Then select Send Secret and enter the secret (CHAP term for password) your ISP gave you.
If your ISP uses CACHE-TOKEN, select Send User Name and enter the user name your ISP gave you to connect. Select Send Password and enter your password.

1. Select Ethernet IP Address and enter the first IP address from the IP address range your ISP has given you. This will be the Netopia Router’s IP address.
If Network Address Translation is enabled in the Easy Setup connection profile, the Ethernet IP Address defaults to an address within a range reserved by the Internet address administration authority for use within private networks, 192.168.1.1.
Because this is a private network address, it should never be directly connected to the Internet. Using NAT for all your connection profiles will ensure this restriction. See “IP Setup, SmartIP and Network Address
Translation” on page 10-1 of this guide for more information.
2. Select Ethernet Subnet Mask and enter the subnet mask your ISP has given you. The Ethernet Subnet Mask defaults to a standard class C mask (for unlimited user models; smaller, for restricted user models).
3. Select Domain Name and enter the domain name your ISP has given you.
4. Select Primary Domain Name Server and enter the IP address your ISP has given you.
5. The Default IP Gateway defaults to the remote IP address you entered in the Easy Setup connection profile. If the Netopia Router does not recognize the destination of any IP traffic, it forwards that traffic to this gateway.
Do not confuse the remote IP address and the default gateway’s IP address with the block of local IP addresses you receive from your ISP. You use the local IP addresses for the Netopia R2121’s Ethernet port and for IP clients on your local network. The remote IP address and the default gateway’s IP address should point to your ISP’s router.
6. To use DHCP and (if installed) MacIP address serving, toggle IP Address Serving to On. Note: For information about dynamic IP address serving, see “IP Setup, SmartIP and Network Address

Upgrade Feature Set

You can upgrade your Netopia R2121 by adding new feature sets through the Upgrade Feature Set utility. See the release notes that came with your router or feature set upgrade or visit the Netopia web site at
www.netopia.com for information on new feature sets, how to obtain them, and how to install them on your Netopia R2121.

Logging

You can configure a UNIX-compatible syslog client to report a number of subsets of the events entered in the router’s WAN Event History. See “WAN Event History” on page 13-6.The Syslog client (for the PC only) is supplied as a .ZIP file on the Netopia CD.
Select Logging from the System Configuration menu. The Logging Configuration screen appears.

8-14 User’s Reference Guide
By default, all events are logged in the event history.
By toggling each event descriptor either Yes or No, you can determine which ones are logged and which are
ignored.
You can enable or disable the syslog client dynamically. When enabled, it will report any appropriate and
previously unreported events.
You can specify the syslog server’s address either in dotted decimal format or as a DNS name up to 63
characters.
You can specify the UNIX syslog Facility to use by selecting the Facility pop-up.

Installing the Syslog client

The Goodies folder on the Netopia CD contains a Syslog client daemon program that can be configured to report the WAN events you specified in the Logging Configuration screen.
To install the Syslog client daemon, exit from the graphical Netopia CD program and locate the CD directory structure through your Windows desktop, or through Windows Explorer. Go to the Goodies directory on the CD and locate the Sds15000.exe program. This is the Syslog daemon installer. Run the Sds15000.exe program and follow the on screen instructions for enabling the Windows Syslog daemon.
When using syslog with a switched connection, if the host you are logging into is located on the WAN, the act of tearing down the call generates WAN events. This requires the torn down line to come back up, effectively making a call that will go up and down continuously. This will only occur when the router tears down the call. If the call is cleared remotely the redial restriction takes precedence and the packets are transparently aged out of the queue.

The Netopia R2121 Dual Analog Router can answer calls as well as initiate them. To answer calls, the Netopia R2121 uses a Default Answer Profile. The Default Answer Profile controls how incoming calls are set up, authenticated, filtered, and more.
This chapter also describes how to use the Netopia R2121’s SmartPhone™ feature. With SmartPhone, other analog devices such as telephones, facsimile machines, or modems can connect to the Netopia R2121 and communicate over the same lines. The Netopia R2121 with SmartPhone provides:
Caller ID support for call authentication
distinctive ring detection, primarily for party line sharing
parallel off-hook detection, preventing the Netopia R2121 from initiating calls when the telephone line is
otherwise busy
auxiliary telephone control, allowing management of whether a “downstream” phone can pre-empt or
interfere with a Netopia R2121 data call. This is also called Call Bumping and Squelch Blocking.

Enter the optional telephone or Directory Numbers for the two onboard modems to provide the Netopia
R2121 with the information needed to establish a two-channel call using MP or BAP. This will advise the remote side of an inbound data call how to connect to a second channel.
Note: When placing multi-channel calls, the answering equipment must either:
be in a “hunt group,” where a single telephone number services multiple lines, or
the answering side must implement MP or BAP as a method to advise the calling side what number(s)
to use. ISPs or corporate IS groups will meet these conditions. For other non-standard dialup connections, you
should verify that one or the other of these conditions is true.
You may choose to selectively Answer inbound calls, based on a distinctive ring pattern, on each onboard

Default Answer Profile for Dial-in Connections
The Netopia R2121 Dual Analog Router can answer calls as well as initiate them. To answer calls, the Netopia R2121 uses a Default Answer Profile. The Default Answer Profile controls how incoming calls are set up, authenticated, filtered, and more.
How the Default Answer Profile works
The Default Answer Profile works like a guard booth at the gate to your network: it scrutinizes incoming calls. Like the guard booth, the Default Answer Profile allows calls based on a set of criteria that you define.
The main criterion used to check calls is whether they match one of the Connection Profiles already defined. If PAP or CHAP authentication is being used, the default profile checks that the incoming call’s name and pass­word/secret match the receive name and password/secret of a Connection Profile. If P AP or CHAP is not being used, an incoming call is matched to a Connection Profile using the remote network’s IP address (that is, the caller is defined as the destination of a particular connection profile).
If an incoming call is matched to an existing Connection Profile, the call is accepted. All of that Connection Profile’s parameters, except for authentication, are adopted for the call.
You could set up the Default Answer Profile to allow calls in even if they fail to match a Connection Profile. Continuing the guard booth analogy, this would be like removing the guards or having them wave all calls in, regardless of their source.
Managing Voice and Data Calls 9-5
If an incoming call is not required to match a connection profile, and fails to do so, it is accepted as a standard IP connection. Accepted, unmatched calls adopt the call parameter values set in the Default Answer Profile.
To determine the call parameter values that unmatched calls will adopt, customize the Default Answer Profile parameters in the Default Answer Profile screen.
Customizing the default profile
You can customize the Netopia Router’s default profile in the Default Answer Profile screen.
1. Select Default Answer Profile in the WAN Configuration screen. Press Return. The Default Profile screen appears.
Default Answer Profile
Calling Number Authentication... Preferred
Must Match a Defined Profile: Yes
PPP Authentication... PAP Bandwidth Allocation... BAP
Configure values which may be used when receiving a call in this screen.
2. To enable CNA-authentication, select Calling Number Authentication in the Default Answer Profile screen and choose one of the following settings:
Ignored: Calling Number Authentication (CNA) is not in effect. Preferred: This is the default setting. Authentication is attempted if the calling number is available. If
authentication fails, or the calling number is not available, the call proceeds as usual and the caller may still connect successfully. Use this setting if you expect to receive both regular and CNA-authenticated calls.
Required: Authentication is attempted if the calling number is available. If authentication fails, or the calling number is not available, the Netopia Router disconnects the caller. Use this setting if you require all calls to be CNA-authenticated.
Calling Number Authentication (CNA), is an application of CallerID. It is a method of verifying that an incoming call is originating from an expected site. Using CNA, you can increase the security of your network by requiring that callers not only possess the correct PPP authentication information, but also are calling from a particular physical location.
9-6 User’s Reference Guide
CNA works by checking the calling number that the Netopia Router receives during the initial setup phase of an incoming call against a set of stored numbers. Each number in the stored set is defined in a specific connection profile. When a match occurs, the incoming call is handled by the connection profile containing the matched number.
Using CNA can also provide cost savings because calls are not billed during the CNA phase. With CNA, a caller can set up a connection to the Netopia Router without incurring any charges by accessing a dial-back connection profile. If the caller’s rates are higher than those charged to the Netopia Router’s return call, then using CNA has saved the difference.
CNA should be available where CallerID services are available. Y ou will need to consult with your telephone service provider to find out if your line is provisioned for CallerID.
Also note that if the calling side has instructed the phone company to block delivery of its caller ID, the answering side will not be able to authenticate.
If your line does not support the appropriate service, CNA may not work properly.
3. To force incoming calls to match connection profiles, select Must Match a Defined Profile and toggle it to Yes. Incoming calls that cannot be matched to a connection profile are dropped. To allow unmatched calls to be accepted as standard IP or IPX connections, toggle Must Match a Defined Profile to No.
If Must Match a Defined Profile is set to Yes, the answer profile only accepts calls that use the same authentication method defined in the Authentication item. If PAP or CHAP are involved, the caller must have a name and password or secret that match one of the connection profiles. The caller must obtain these from you or your network administrator before initiating the call.
For example, if Must Match a Defined Profile is set to Yes, and Authentication is set to PAP, then only incoming calls that use PAP and match a connection profile will be accepted by the answer profile.
If authentication in the Default Answer Profile is set to CHAP, the value of the CHAP Challenge Name item must be identical to the value of the Send Host Name item of the Connection Profile to be matched by the caller.
If Must Match a Defined Profile is set to No, Authentication is assumed to be None, even if you’ve set it to PAP or CHAP. The answer profile uses the caller’s IP address to match a connection profile. However, the answer profile cannot discover a caller’s subnet mask; it assumes that the caller is IP address:
Class A addresses are assumed to have a mask of 255.0.0.0 Class B addresses are assumed to have a mask of 255.255.0.0 Class C addresses are assumed to have a mask of 255.255.255.0. Class C address ranges are generally
the most common subnet allocated. If a remote network has a non-standard mask (that is, it uses subnetting), the only way for it to successfully
connect to the Netopia Router is by matching a connection profile. In other words, you will have to set up a connection profile for that network.If Must Match a Defined Profile is set to No, you can also set the following parameters for accepted calls that do not match a connection profile:
