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.

SMC7301TAApplications

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.

A Physical Look at the SMC7301TA

Rear Panel:

The following illustration shows the rear panel of the SMC7301TA:

SWITCH WAN LAN CONSOLE AC 7.5V

One RJ-45 ISDN port for connectio n to your ISDN line.

One RJ-45 10/100 Mbps LAN port for connection to a workstation, or to

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 the 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.
