Introduction

Congratulations on your purchase of a D-Link DI-304/DI-304M remote access router with integrated Ethernet switch and ISDN TA. No larger than an ordinary modem, your router offers inexpensive yet complete telecommunications and internetworking solutions for your home or branch office. It is ideal for applications such as Internet/intranet access, Wide Area Networking, Electronic Commerce, and Remote Network Access.

This complete solution also includes remote dial-in user support, an Internet singleuser account (Network Address Translation) option, extensive network management capabilities, and solid security features.

The DI-304/DI-304M provides multiple users with efficient and reliable access over a single ISDN BRI, DSL line, or Cable Modem (Dynamic IP is not supported) service to the Internet and corporate LAN for using E-mail, sharing documents, Web surfing, file transfers, etc. Moreover, the provision of a built-in four-port Fast Ethernet Switch and one Uplink port may give cost-effective workgroup connectivity over Ethernet.

In addition to improving the productivity of employee, flexible telecommuting access, and affordable management cost, the DI-304/DI-304M accommodates room for business growth from 4 computers or more.

The broadband access protocol supports PPPoE, PPTP, and Static IP. These protocols comply with worldwide Ethernet-based DSL/Cable Modem standards. For traditional ISDN users, the DI-304/DI-304M features a built-in Virtual TA (Remote CAPI) server that operates as a CAPI-based ISDN TA for LAN users. To run FAX transmission or data transfer services, users need to install a Virtual TA client driver on the PCs and use third-party CAPI-based software.

The Router provides seamless migration from ISDN to a broadband connection for multiple SOHO users and easy usage of ISDN for backup-dial and/or remote access while concurrently using the DSL/Cable modem connection.

PPPoE/PPTP allows users on the LAN interface to setup a dial-on-demand DSL connection sharing the same IP account, and paying for only one connection. The idle-time out function prevents wasted connection charges by shutting down the connection when it is idle. No PPPoE/PPTP client software is required for the computers.

DI-304/DI-304M ISDN Remote Router

Product Features

The DI-304/DI-304M router is packed with features that give it the flexibility to provide a complete networking solution for almost any small to medium-sized office environment.

DI-304/DI-304M ISDN Remote Router

Ease of Installation

Your DI-304/DI-304M is a self-contained unit that is quick and easy to install. Physically, it resembles an external modem; however, it is a combination ISDN router and Ethernet switch, and it uses twisted-pair Ethernet cables to connect to the host network.

Built-in Switch

A dual-speed NWay switch, the DI-304/DI-304M provides four ports for connecting network end nodes—single-user computers, servers, bridges, other routers, etc.— through standard “straight-through” twisted-pair cables and one port for making an “uplink” connection to another hub or switch through the same type of straightthrough cable used to connect end nodes.

ISDN Basic Rate Interface (BRI)

Using a standard S/T the DI-304/DI-304M supports DSS1 ISDN switches. The two ISDN B-channels can be used independently for two destinations, or they can be bundled together for one high-bandwidth connection supporting bandwidth-ondemand.

Standard Phone Jacks (Just for DI-304M)

The router is equipped with two standard phone jacks for connecting telephones, fax machines, or modems. This allows the ISDN line to be used for voice as well as data calls.

Dial On Demand

The Dial On Demand feature allows a DI-304/DI-304M to automatically place a call to a Remote Node whenever there is traffic coming from any workstation on the LAN (Local Area Network) to that remote site.

Bandwidth On Demand

Bandwidth-on-Demand (BOD) for ISDN Interface: As the ISDN BRI interface has two independent B channels, the BOD mechanism allows you to automatically add/drop a B channel according to data traffic throughput.

Full Network Management

The DI-304/DI-304M incorporates SNMP (Simple Network Management Protocol) support and menu-driven network management via a Telnet connection or an embedded Web configuration program.

PPP Security

The DI-304/DI-304M supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol).

RIP-1/RIP-2

Routing Information Protocol (RIP) Support: Used in most LAN-to-LAN applications. The RIP protocol exchanges routing information between routers.

DHCP Support (Dynamic Host Configuration Protocol)

DHCP (Dynamic Host Configuration Protocol) allows IP addresses to be automatically and dynamically assigned to hosts on your network.

Networking Compatibility

The DI-304/DI-304M is compatible with remote access products from other companies such as Ascend, Cisco, and 3Com. Additionally, Microsoft Windows 95, 98, 2000, and Windows NT remote access capability are all supported.

Firmware Upgrade (TFTP) Server

Using this server and the Firmware Upgrade Utility software, you may easily upgrade to the latest firmware whenever enhanced features are added.

DI-304/DI-304M ISDN Remote Router

Web (HTTP) Server

A Web browser is the most common tool used to surf the Internet. You may use Microsoft Internet Explorer or any Netscape browser to configure the Router. It’s as easy as surfing a Website.

Virtual TA Server (VTA)

The terminology Virtual TA means the DI-304/DI-304M can operate as traditional ISDN TA to transmit and receive data, FAX, and voice transmissions via third-party software running on a desktop computer. In fact, a virtual TA server works as a network TA to exchange packets between an ISDN BRI and an Ethernet LAN. Therefore, desktop computers can use the ISDN line resource via an Ethernet LAN. In short, multiple users can share a network TA for backward compatibility with traditional applications, such as BBS, file transfer, sending/receiving FAXs, etc.

Remote Access Server (RAS)

RAS provides remote dial-in access services for home workers, branch offices, or telecommuters. DI-304/DI-304M routers offer 10 dial-in user profiles, including an authentication mechanism through CHAP/PAP and Calling Line Identification (CLID), secure callback functions, and 16 Lan-to-Lan Dialer Profiles.

Domain Name Server (DNS) Proxy

The DNS proxy maintains a DNS cache, including a mapping table between domain names and IP addresses. The proxy also remembers DNS query packets sent through the router and saves them into its own DNS cache. For enhanced speed, when a DNS query packet enters the router, the proxy searches its local DNS cache.

DI-304/DI-304M ISDN Remote Router

If matched, the router sends an answer to the host that sent the DNS query packet. Only unmatched DNS queries require querying a WAN Domain Name Server.

Telnet Terminal Server

The Telnet User Interface (TUI) is an efficient method of configuring and managing routers. It utilizes a traditional command-line user interface and is mainly for advanced configuration, management, and troubleshooting.

Built-in Flash ROM

The Flash ROM memory saves the router firmware and configurations, even after power down.

Point-to-Point over Ethernet (PPPoE) Client Support

If you are a DSL user, the router has a built-in PPPoE client for establishing a DSL link connection with the ISP. There is no need to install a further PPPoE driver on your computers.

Point-to-Point Tunnelling Protocol (PPTP) Client Support

Some DSL modems (e.g. Alcatel modems) only provide a PPTP local connection for an end user computer. The DI-304/DI-304M has a built-in PPTP client for establishing a DSL link transport protocol for your entire local network. There is no need to install a PPTP driver on your computers.

Firewall

In addition to the built-in NAT mechanism, the Router features another powerful firewall to protect your local network or to deny specified local users access to unauthorized network services.

Remote Management

The system manager can remotely manage the routers through an ISDN remote dialin, ISDN, or DSL WAN interface.

Applications for your DI-304/DI-304M

Some applications for the DI-304/DI-304M include:

Internet Access

Your DI-304/DI-304M supports TCP/IP protocol, which is the language used for the Internet. It is also compatible with access servers manufactured by major vendors such as Cisco and Ascend.

Network Address Translation (NAT)

For small office environments, the DI-304/DI-304M allows multiple users on the LAN to access the Internet concurrently through a single Internet account. This provides Internet access to everyone in the office for the price of a single user.

NAT address mapping can also be used to link two IP domains via a LAN-to-LAN connection.

LAN-to-LAN Enterprise Connections

The DI-304/DI-304M can dial to or answer calls from another remote access router connected to a different LAN. The DI-304/DI-304M supports TCP/IP and has the capability to bridge any Ethernet protocol.

Remote Dial-In Server

The DI-304/DI-304M allows Remote Dial-in Users to dial in and gain access to your LAN. This feature enables users that have workstations with remote access capabilities, e.g., Windows 98, to dial in using an ISDN terminal adapter (TA) to access the network resources without physically being in the office.

adapter and plug the power adapter into a suitable AC outlet.

♦ STATUS— Should be blinking if the router is functioning properly.

♦ ISDN – LINK— Indicates that the router has an ISDN line connected to

the ISDN interface and it has been successfully initialized.

Note: On some NT1 boxes, the LINK indicator will go off when the ISDN line has

been idle for a while. When the router is dialing or answering a call, it should be on again.

♦ ISDN – B1 and B2— On if there is an active ISDN session on that

channel or if that channel is making or receiving a call.

♦ LINK/ACT— 1 through 4 These indicators light up when a port is

connected to a powered-on Ethernet/Fast Ethernet station. The LEDs blink when information is transmitted or received on a port.

♦ 100/10M – 1 through 4 These indicators light up when a port is

operating at 100Mbps. Otherwise, if this indicator is dark and the corresponding LINK indicator is lit, then the port is operating at 10Mbps.

♦ PHONE – 1 (DI-304M only) — Lights up when standard phone port 1

is in use.

♦ PHONE – 2 (DI-304M only) — Lights up when standard phone port 2

is in use.

DI-304

DI-304M

The DI-304 has a power jack, an uplink port, four RJ-45 ports, an ISDN port on the rear panel, and a factory reset button. The DI-304M is identical other than the addition of two RJ-11 phone ports. Please note that only the D-Link supplied power adapter should be connected to the power jack.

♦ POWER — This socket is an 18 volt, 750mA power input jack. If the

power adapter included with the router has been lost or misplaced, please ensure that the replacement adapter meets both the voltage and amperage requirements.

♦ ETHERNET – The Ethernet ports function as a normal, dual speed

NWay Ethernet switch.

♦ Uplink – This port is used to connect the router to another

switch or hub using a straight-through twisted-pair cable. When the Uplink port is used, Port 1x is unavailable.

♦ Ports 1x to 4x – These four ports can be used to connect

end-stations to the router using straight-through cables.

♦ ISDN – This socket is used to connect the ISDN line to either an NT-1

or directly to the ISDN wall jack, depending on the type of service delivered by your phone company.

♦ PHONE 1 and 2 (DI-304M only) – These normal telephone jacks can

be used to connect telephones or fax machines to the router for use over the ISDN lines. Plug telephone devices into these jacks as you normally would into a telephone wall socket.

jack on the rear panel of the router.

2. The Act LED should be blinking once every 2 seconds.

Connecting to the Ethernet

A. Connecting to PCs:

1. Attach the Ethernet cable to any P1 ~ P4 port.

2. Connect the other end of the Ethernet cable to your PCs' installed network interface card (NIC).

3. The LED indicators at both the Ethernet port and the NIC should be ON.

Note: If the Ethernet cable is not long enough to reach your PCs, purchase a longer

straight-through Cat. 5 UTP or STP Ethernet cable.

B. Connecting to an External Ethernet Hub:

1. Attach the Ethernet cable to the Uplink port.

2. Connect the other end of the Ethernet cable to the external Ethernet hub or switch.

3. The LED indicators on both the Uplink port and the external Ethernet hub or switch should be ON.

Note: If the Ethernet cable is not long enough to reach the external hub/switch,

purchase a longer straight-through 10BASE-T Ethernet cable, or connect two shorter cables to create a cable of sufficient length.

Connecting to an ISDN BRI Line

A. S/T-Interface Model

1. Locate the ISDN cable.

2. Plug one of the RJ-45 connectors on the cable into the ISDN port on the rear panel of the router.

3. Plug the other end of the cable into any of the NT-1 (or NT1 plus) S/Tinterface ports.

B. U-Interface Model

1. Locate the ISDN cable.

2. Plug one of the RJ-45 connectors on the cable into the ISDN port on the rear panel of the router.

3. Plug the other end of the cable into the ISDN wall outlet.

Connecting to a DSL/Cable Modem

DI-304/DI-304M ISDN Remote Router

The router supports connection of a DSL modem via an Ethernet interface only. Non-Ethernet interface DSL modems, such as USB and ATMF-25, will not be supported.

1. Attach the Ethernet cable to the Ethernet port of the DSL/Cable modem.

2. Plug the other end of the cable into the P1 to P4 port.

3. If the port’s LED is not bright, please change the direct cable to cross cable.

The hardware installation is now complete. The following sections will guide you through setting up your management PC and connecting to the Web Configurator.

Setting Up a Management PC

The Router has a built-in HTTP (Web) server for configuration. Before you use the router to access the Internet, you should set up a management PC to log into the router for further configuration. The management PC may be configured with a fixed or dynamically assigned IP address. For a fixed IP address, use an IP address from a 192.168.0.0/24 network, such as 192.168.0.2. For the dynamic IP address, you need to set the PC as a DHCP client, and then restart or renew the network settings. The DHCP server embedded in the router is enabled by default so the PC will then be assigned an IP address and related settings by the router. The following examples are for a Microsoft Windows 95/98 machine set to use a dynamic IP address. For other operating systems, please refer to the OS user manuals.
