Overview of the SMC7301TA ISDN

Router

The SMC7301TA ISDN Router is a small desktop router that sits between your local Ethernet network and a remote network (For example, the Internet or a remote office). The SMC7301TA contains an ISDN S/T interface, a 10Mbps WAN port, a 10/100Mbps LAN port, and a conso le port for management capability. Data comes into the SMC7301TA from the LAN and then is “routed” to the remote network, and vice versa. In addition to its capability to route IP traffic, the SMC7301TA also acts as a bridge for other network protocols , such as Appletalk or SNA.

SMC7301TA Applications

The main functions of the SMC7301TA are to support devices on your LAN to access the Internet, to support remote users to dial -in and access resources on your LAN, and to support communications among branch

offices.

Accessing the Internet

The most common use for the SMC7301TA is to provide Internet access, so that everyone on your LAN can surf the web, send/receive e -mail, or share files. The SMC7301TA automatically acquires the necessary IP addre ss when the connection to the Internet is established. You don’t need to apply for or assign an IP address to each PC or workstation on your network. There are two alternatives in establishing the connection between the LAN and the Internet: either thr ough ISDN or through an xDSL/cable modem. With built-in PPPoE (Point-to-Point Protocol over Ethernet) support, the SMC7301TA provides virtual dial -up environments and allows end users to connect via an xDSL/cable modem to the Internet whenever they wan t. Alternatively, end users can connect via an ISDN connection to the Internet. In this situation, the SMC7301TA supports “bandwidth on demand”. For example, any user’s initial intent to access the Internet will trigger a B-channel connection to be se t up. As the traffic builds (for example, more users try to access the Internet, or the same user generates a lot of traffic), the SMC7301TA will establish the second connection through the other B-channel. As traffic decreases, one B -channel will be taken down, until finally, after a configurable period of inactivity, the remaining B -channel will also be disconnected.

Supporting Dial-in Access to Your Network

Under an ISDN connection you can set up your SMC7301TA to allow users to connect to your ne twork and share resources from their homes while

they are traveling. The SMC7301TA’s built -in “Broadband Router Manager” makes the necessary setup a snap. As a security feature, after a user calls in, the SMC7301TA will hang up and call that user back at a pre-configured telephone number.

Creating Your Own Private Wide Area Network

Under an ISDN Connection you can also create your own private wide area network with the SMC7301TA and allow two or more remote networks to connect to one another and share resources. The remote network can use an ISDN router from a different vendor - as long as it also supports LAN -to-LAN communication.

Security Overview

More and more people are concerned about security of their data in this Internet era. The SMC7301 TA provides many ways to help make your network and your data secure:

 All dial-in users and LAN -to-LAN communications require

CHAP/PAP/MS-CHAP authentication (basically, user name and

password).

 SMC7301TA also supports call back for dial -in users so that remote

users are really who they say they are.

 ISDN Caller ID may be used for incoming call authentication.  SMC7301TA uses a private IP addressing scheme to prevent devices

on your LAN from being accessed by users on the Internet.

 Console and Telnet Configu ration provide password protection.  IP packet filtering may be used to enhance security requirements.

another switch or hub.

 One RJ-45 10 Mbps WAN port for connection to an xDSL/cable

modem.

 One RS-232 DB-9 port to enable console management capability.  One 7.5V AC power connector for connection to an AC power adapter

(included as part of the product).

 One DIP switch on the rear panel allows you to set the terminating

resistor conveniently if the single ISDN line supports more than one ISDN terminal equipment at the sa me time.

The LEDs on the front

There are seven LEDs on the front of the SMC7301TA that show the status of Power, LAN activity, WAN activity, and ISDN activity. You can tell at a glance if your SMC7301TA is functioning properly, and if there is any t raffic passing through. Note that the second, the third, and the forth LED (left to right when you are facing the front of the SMC7301TA) are dual -colored. Please note that the third or the forth LED will flash with orange color when collisions occur on th e LAN port or on the WAN port. The sixth or seventh LED will flash with green color, respectively, when data is transmitted over the corresponding B channel. The following table shows a brief description for each LED.

Chapter 2 Installing the

SMC7301TA

Hardware Installation

Follow these steps to complete the hardware installation for the SMC7301TA:

 Connect the SMC7301TA from the WAN port to an xDSL/cable modem,

or attach an ISDN line to the ISDN port (S/T interface).

 Connect your PC to the RJ -45 LAN port. Two or more PCs can be

connected via a multi-port hub or switch which you can connect to the RJ-45 LAN port of the SMC7301TA.

 Plug the power adapter into a wall outlet and the AC connector on the

back of the SMC7301TA.

 The RS-232 port is only used to connect a terminal to run the

Command Line Interface using the null modem cable. (This is an

optional connection.)

 There is a DIP switch located on the rear panel for setting the

terminating resistor. You only need to adjust this switch if ther e are two or more external ISDN equipment attached to the local telephone line.

Setting Up a Windows PC

This section describes the configuration required by LAN -attached PCs which communicate with the SMC7301TA, either to configure the SMC7301TA, or for network access. These PCs must have an Ethernet interface installed properly, be connected to the SMC7301TA either directly or through an external hub or switch, and have TCP/IP installed and configured to obtain an IP address through a DHCP server. Directly connect a Windows 95/98/2000 PC to the SMC7301TA. If TCP/IP is not already installed, follow the steps below for its installation.

Note: Any TCP/IP capable workstation can be used to communicate with or through the SMC7301TA. To configure oth er types of workstations, please consult the manufacturer’s documentation.

Step 1: Connect your PC to the SMC7301TA’s LAN port or to a hub/switch that is connected to the SMC7301TA as depicted above. . Step 2: From the Win95/98 Start Button, select Settings, then Control Panel. The Win95/98 Control Panel will display. Step 3: Double-click on the Network icon.

Step 4: Check your list of Network Components in the Network window Configuration table. If TCP/IP has already been installed, go to Step 8. Otherwise, select Add to install it now.

Step 5: In the new Network Component Type window, select Protocol.

Step 6: In the new Select Network Protocol window, select Microsoft in the

Manufacturers area.

Step 7: In the Network Protocols area of the same window, select TCP/IP, then click OK. You may need your Win95/98 CD to complete the installation.

After TCP/IP installation is complete, go back to the Network window shown in Step 4.

Step 8: Select TCP/IP in the list of Network Components. Step 9: Click Properties, and check the settings in each of the TCP/IP

Properties window:

 Bindings Tab: both Client for Microsoft Networks and File and

printer sharing for Microsoft Networks should be selected.

 Gateway Tab: All fields should be blank.  DNS Configuration Tab: Disable DNS should be selected  IP Address Tab: Obtain IP address automatically should be selected

Step 10: With the SMC7301TA powered on and connected to the LAN, reboot the PC. After the PC is re -booted, you should be ready to configure the SMC7301TA. See Chapter 3.

Chapter 3 Internet Access

Configuration

Once you have completed the installation stage and have configured PCs in the way described in chapter two, you are ready to configure the SMC7301TA for actual applications. This chapter describes how to configure you’re SMC7301TA for basic Internet access, as well as Internet access with advanced features. In the following sections you will be shown how to configure the SMC7301TA for basic Internet acce ss in less than five minutes using the web-based “Broadband Router Manager”.

Using Different Browsers to

Configure the SMC7301TA

To configure your SMC7301TA, you can use popular browsers such as Netscape 4.x and Internet Explorer 4.x and 5.x. The fol lowing describes how to access the “Broadband Router Manager” through IE or Netscape Navigator.

Netscape Navigator 4.x:

In the Location box (where you normally enter the URL address), enter

the default private IP address of SMC7301TA followed by hitt ing the return key: http://192.168.2.1

Internet Explorer 4.x and 5.x:

In the Address box (where you normally enter the URL address), enter the default private IP address of SMC7301TA followed by hitting the return key: http://192.168.2.1

Logging On

A password screen will ask you to log on after you enter the default IP address described above. If you are logging on for the first time, you should accept the factory default password (which is “password”). The password is always displayed as a string of asterisks (“*”). Clicking the Log On button will begin the Configuration process for the SMC7301TA.

The next time you log in, even if you have modified the password, the default password (“password”) will still be us ed as the default. You need to change it to the correct password before you will be let in. No matter what password you use, each character will always be displayed as a “*”. If you forget the password, you need to follow the steps described later in the chapter to be able to log on.

After clicking Log On, the following screen will display, and you must select either ISDN or WAN as the interface for Internet Access. Click Next to proceed in the configuration process. Please see the following text for de tails.

Customizing the User Interface to

Fit Your Specific Needs

When you enter into the main configuration window, click “ Customize User Interface” in the SYSTEM TOOLS Menu on the left side of the screen, this will allow you to customize the Broadband Router Manager to suit your own specific needs. The selections you make determine what configuration menus and buttons will appear in the screen. For example, if you select Basic Internet Access only, the interface will only displa y buttons that you need for basic Internet access. If you subsequently use Broadband Router Manager to configure the SMC7301TA for other applications, you can return to this screen to “re-customize” your interface by selecting Customize User Interface from the SYSTEM TOOLS Menu.

Basic Internet Access

Select this option if you need basic Internet access. This will enable you to configure Internet Access for all of your LAN users. There are two Internet access interface selections provided by the SMC7301TA: through ISDN or through WAN.

Internet Access with Advanced

Configuration

Select this option if you want to configure advanced options, such as changing the private IP address (for example, when you intend to create your own private WAN between multiple SMC7301TA routers), or adding a public IP address (e.g., when you want to install servers on the LAN which are accessible from the Internet).

Access to/from Remote Site (e.g., Branch Office)

Select this option if you want to create connec tions to other LAN sites, that is, users at each site can share resources. If you use Windows PCs, for example, then from the Network Neighborhood facility, you can access files from remote PCs directly. This feature is valid only when you select ISDN as

the interface for Internet access.

Dial-in Access for Off-Site Users

Select this option if you want to allow users on a stand -alone computer to dial in and access resources on your network. This feature is valid only when you select ISDN as the interfa ce for Internet access.

Click Next when you have selected the options you want. The quantity of selections is not limited but step -by-step configuration is recommended.

Overview of Broadband Router

Manager Screen

Before you begin the configuration process, take a moment to look at the Broadband Router Manager screen. Look for these areas:

 Menu Window (in the left side of the screen)  Configuration Window (in the right -upper side of the screen)  Message Window (in the right -lower side of the screen)  System Status Monitoring Window (the separate window)

Menu Window

This part of the browser screen contains items you can click to display the various screens for configuring your SMC7301TA.

Configuration Window

This is the window where the actual configuration screens appear.

Message Window

Whenever appropriate, the SMC7301TA will display system status or error messages in this window. For example, when you try to connect to the Internet, if you had configured your password incorrectly, the message window will display an appropriate message.

System Status Monitoring Window

This section displays statistics and the status of all interfaces. This window is invoked as a separate browser screen from the main Broadband Router Manager browser screen and appears automatically each time you start Broadband Router Manager . If you close this window, you can always restart it by clicking System Status in the MONITORING Menu. It does not contain any toolbars or browser menu buttons. Although the main Broadband Router Manager screen will timeout, this screen will not, and will continue to be operational as long as it is active.
