GLOSSARY......................................................................... 147 INDEX ................................................................................ 157 ISDN Router User' Guide s Introduction Congratulations on your purchase of a D-Link DI-300 series Remote Access Router. In a modem-sized box, your router offers inexpensive yet complete telecommunications and internetworking solutions for your home or branch office. It is ideal for everything from Internet browsing to receiving calls from Remote Dial-in Users and making LAN-to-LAN connections to Remote Nodes. Distinguishing features of the DI-300 series include support for a full range of networking protocols such as TCP/IP (Transmission Control Protocol/Internet Protocol, also known as IP), Novell IPX (Internet Packet Exchange), and Transparent Bridging. DI-300: DI-300W: DI-300M: ISDN S/T interface, IP routing ISDN U interface, IP routing ISDN S/T interface, IP/IPX routing, bridging DI-300MW: ISDN U interface, IP/IPX routing, bridging This complete solution also includes Remote Dial-in User support, an Internet Single User Account (Network Address Translation) option, extensive Network Management, and solid security features. Introduction 1 NOTE: Throughout the remainder of this manual, the term "DI-300" refers to any DI-300 or DI-300W, and the term "DI-300M" refers to any DI-300M or DI-300MW. Features Each DI-300 series router is packed with features that give it the flexibility to provide a complete networking solution for almost any user. Ease of Installation Your DI-300 or DI-300M is a self-contained unit that is quick and easy to install. Physically, it resembles an external modem except for the fact that it is a router and uses an Ethernet cable to connect to the host network. ISDN Basic Rate Interface (BRI) Using a standard S/T or U Interface (the DI-300 and DI-300M use the S/T interface, while the DI-300W and DI-300MW use the U interface) the DI-300 and DI-300M support a full range of switch types. The switch type depends on the CO (Central Office) switch your ISDN line is connected to. See the ISDN Switch Types chapter for more information on North American, European, and Asian ISDN firmware and switch types supported by these routers. 2 Introduction The two B-channels can be used independently for two destinations. Or they can be bundled for one connection to support bandwidth-on-demand. ISDN Leased Line If the router is set up for an ISDN leased line (that is, if any option but Switch/Switch or Switch/Unused is selected for the B Channel Usage control in setup menu 2, "ISDN Setup," and the Transfer Type control is set to Leased in either setup menu 4, "Internet Access Setup," or setup menu 11.1, "Remote Node Profile"), the router will automatically initialize the leased-line connection each time it is powered up or setup menu 2, 4, or 11.1 is saved. The DI-300 and DI-300M implement the PPP echo mechanism for verifying ISDN leased line status. The setting of the Idle Timeout control in setup menu 11.1 will be used as the interval between two LCP_Echo_Req messages. It is supposed that there exists an echo reply corresponding to an echo request. Whenever an echo request is sent, the counter will be incremented by one. The send counter will be reset to zero after an echo response is received. The leased-line error recovery mechanism will be triggered after the send counter reaches 4. If the Idle Timeout control is set to zero, the PPP echo mechanism will not be used. Multiple Networking Protocol Support The DI-300M is a multi-protocol router. It supports TCP/IP, Novell IPX, and Transparent Bridging. Introduction 3 Dial On Demand The Dial On Demand feature allows a DI-300 or DI-300M to automatically place a call to a Remote Node whenever there is traffic coming from any workstation on the LAN to that remote site. Bandwidth On Demand Your DI-300 or DI-300M supports bandwidth up to 128 Kbps over a single ISDN BRI line. It incorporates PPP/MP (Point-to-Point Protocol/Multilink Protocol) to bundle two B channels over a BRI line. In addition, the router dynamically allocates bandwidth between the two B channels, increasing or decreasing bandwidth as needed to allow for greater efficiency in data transfer. It supports BAP (Bandwidth Allocation Protocol) and BACP (Bandwidth Allocation Control Protocol) to manage the number of links in multilink bundle. Full Network Management The DI-300M incorporates SNMP (Simple Network Management Protocol) support and menu-driven network management via an RS-232 or Telnet connection. In addition, both the DI-300 and the DI-300M offer the Call Detail Record (CDR) function to help you analyze and manage your telephone bill. RADIUS (Remote Authentication Dial In User Service) The RADIUS feature allows you to use a central external Unixbased server to support thousands of users (DI-300M only). 4 Introduction PPP Security The DI-300 and DI-300M support PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol). MS (Microsoft) CHAP Your DI-300 or DI-300M and a Microsoft Windows 95 or Windows NT server can authenticate each other using Microsoft's proprietary CHAP algorithm. No special setup is needed to support MS CHAP. Everything is done through PPP negotiation between the router and the server. RIP-1/RIP-2 Your DI-300 or DI-300M supports both RIP-1 and RIP-2 (Routing Information Protocol versions 1 and 2) exchanges with other routers. RIP version controls in setup menus 3.2 (TCP/IP and DHCP Ethernet Setup) and 11.3 (Remote Node Network Layer Options) let you control RIP use, and offer the following version options: RIP-1 (accept and send RIP-1 messages only), RIP-2B (accept RIP-1 and RIP-2 messages, both broadcast and multicast, and send RIP-2 messages in broadcast format), and RIP-2M (accept RIP-1 and RIP-2 messages, both broadcast and multicast, and send RIP-2 messages in multicast format). (The suggested choice in both menus is RIP-2B, except in environments where there are routers that do not understand RIP-2 packets at all. "Broadcast," above, means a destination MAC or IP host address consisting of all binary ones; "multicast" means a Introduction 5 MAC address of 01:00:5E:00:00:09 hex or an IP destination address of 224.0.0.9.) DHCP Support (Dynamic Host Configuration Protocol) DHCP (Dynamic Host Configuration Protocol) allows you to dynamically and automatically assign IP address settings to hosts on your network. Call Control Your DI-300 or DI-300M provides budget management for outgoing calls and maintains a "blacklist" of unreachable phone numbers in order to save you the expense of unnecessary charges. Data Compression The DI-300 and DI-300M incorporate Stac data compression and CCP (Compression Control Protocol). Networking Compatibility The DI-300 and DI-300M are compatible with remote access products from other companies such as Ascend, Cisco, and 3Com. Furthermore, they support Microsoft Windows 95 and Windows NT remote access capability. 6 Introduction Applications For Your DI-300 or DI-300M Some applications for the DI-300 and DI-300M include: Internet Access Your DI-300 or DI-300M supports the 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. Internet Single User Account (SUA) For small office environments, the DI-300 and DI-300M offer a Single User Internet Account (also known as a Network Address Translator, or NAT) from an ISP (Internet Service Provider). This allows multiple users on the LAN (Local Area Network) to access the Internet concurrently for the cost of a single user. Single User Account address mapping can also be used for LAN to LAN connections. Multiprotocol LAN-to-LAN Connection The DI-300 and DI-300M can dial to or answer calls from another remote access router connected to a different network. The DI-300M supports TCP/IP and Novell IPX, and has the capability to bridge any Ethernet protocol. Introduction 7 Telecommuting Server The DI-300 and DI-300M allow 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 95, to dial in using an ISDN terminal adapter (TA) to access the network resources without physically being in the office. What This Manual Covers This manual is divided into five parts. 1. Part One--Getting Started--is structured as a step-by-step guide to help you connect, install, and set up your DI-300 or DI-300M to operate on your LAN. 2.

These chapters are designed as a guide for you to collect the necessary information about your ISDN phone line and the LAN which you will be connected to. Once this information has been collected, it will be used to configure your router. After you have successfully configured your DI-300 or DI-300M, see the appropriate chapters to set up your applications. For Internet Access, see the Configuring for Internet Access chapter starting on page 38. Road Map and Flow The chart below is provided as a step by step guide to successfully installing your DI-300 or DI-300M. Before You Begin 11 Completing the Worksheet Before you continue, locate the worksheet at the end of this chapter. This information worksheet has been provided to help you get through setup and installation of your DI-300 or DI-300M as easily as possible. 12 Before You Begin Ordering Your ISDN Line If you do not have the ISDN line installed already, we suggest that you order it from your telephone company as soon as possible to avoid the long waiting period common when ordering a new line. Use the information in this section to place the order (see the ISDN Switch Types chapter for information on provisioning your ISDN line). If you have already installed your ISDN line, you can check the following section to make sure that you can use all the features of your DI-300 or DI-300M. 1. Contact your local telephone company's ISDN Ordering Center. 2. Find out what type of ISDN service is available. Refer to the ISDN Switch Types chapter to find out the provisioning information for the appropriate switch type and ISDN service. For the U.S., the DI-300W and DI-300MW (U Interface) have been approved by Bellcore and have IOC (ISDN Ordering Code) "S" Capability, EZ-ISDN 1. 3. Provide your telephone company with the proper provisioning information. 4. When the telephone company installs your ISDN line, be sure to obtain the following information: ISDN switch type. ISDN telephone number(s). ISDN Service Profile Identifier (SPID) number(s) (only for North America). Before You Begin 13 Collecting General Setup Information Your DI-300 or DI-300M requires the following system information. You can obtain all the pertinent information from your network administrator. Record this information into the worksheet as it becomes available. This worksheet will later be referred to as you configure your router. System Name--This is the name given to the router for identification purposes. This name should be no more than 8 alphanumeric characters. Spaces are not allowed, but "-" and "_" are accepted. This name can be obtained remotely via the SNMP management protocol and will be displayed as the prompt when the user enters Command Interpreter Mode. Route IP Field--For Internet access, you will need to enable the Route IP Field. See the Configuring for Internet Access chapter starting on page 38 for more details on configuring your router for Internet access. To support Novell IPX, or Bridging, enable the appropriate protocol and reference the related chapters for detailed information. You have now collected all of the general setup information you need. Make sure that you have entered all the values onto the worksheet before proceeding to the next section. Collecting ISDN Phone Line Information After you have successfully installed the ISDN phone line or if you already have one installed, you need to use the ISDN line information to complete the worksheet and configure your router. 14 Before You Begin Your telephone company can give you the following information to configure the DI-300 or DI-300M: Switch Type AT&T 5ESS NI-1 AT&T 5ESS Point to Point AT&T 5ESS Multipoint Northern Telecom NI-1 Northern Telecom Custom DSS1 1TR6 Geography North America North America North America North America North America Europe, Asia Germany No. of Phone #s 2 1 2 2 2 2 2 No. of SPIDs 2 0 2 2 2 N/A N/A Switch Type--This is the type of switch used by your telephone company. Check with your telephone company and choose the appropriate option on the worksheet. For North America, select your ISDN switch type. For DSS1 and 1TR6, verify this field to make sure that you have the proper firmware loaded. B Channel Usage--Determine which connection is appropriate for your B channel and check the corresponding option on the worksheet. If your DI-300 or DI-300M is the only device using the ISDN line, configure B Channel Usage to Switch/Switch so the router device will use both B channels to communicate. If the router is sharing the ISDN line with other devices, configure B Channel Usage to Switch/Unused. If your DI-300 or DI-300M is on a leased line, configure B channel usage to Leased/Leased or Leased/Switch, depending on the setting of the line. Telephone Number(s)--Record on the worksheet the telephone number(s) given to you by your ISDN provider. Some switch types only have one telephone number. These phone numbers should be in a standard digit format (for example, 5551212). Note that these fields will only accept digits, so--and spaces will not be accepted. Before You Begin 15 SPID Number(s)--(For North America only) The SPID (Service Profile Identifier) is a number used by a central office switch for identification purposes. With the switch information, see the previous table for the number of SPIDs you must enter. You have now collected all of the necessary information about your ISDN phone line. Make sure that these values are entered into your worksheet before you continue to the next section. For DSS1 and 1TR6 ISDN, refer to the Installation chapter starting on page 21. Collecting Ethernet Setup Information This section assumes that you are setting up your router for a TCP/IP connection. If you want to configure the system for other protocols (e.g., IPX), refer to the appropriate chapters. Ethernet Interface--Your DI-300 or DI-300M is equipped with an NWay auto-sensing 10/100-Mbps port. Just plug in the cable, and the router will automatically determine the network speed (10 Mbps or 100 Mbps) and mode (full or half duplex) based on the capability and configuration of the attached device. IP Address--An IP Address is required for TCP/IP protocol. The IP Address is a unique 32-bit number assigned to your router. It is written in dotted decimal notation (four 8-bit numbers, between 0 and 255, separated by periods), e.g., 192.68.203.5. Record the IP Address into the worksheet as assigned by your network administrator. Note that every machine on a TCP/IP 16 Before You Begin network (the global Internet, for example) must have a unique IP address; do not assign an arbitrary address to any machine. IP Sub-net Mask--This field is required for TCP/IP protocol. An IP address consists of two parts, the network ID and the host ID. The IP Subnet Mask is used to specify the network ID portion of the address, expressed in dotted decimal notation. Your DI-300 or DI-300M will automatically calculate this mask based on the IP address that you assign. Unless you have special need for subnetting, use the default mask as calculated by the router. The table below lists some examples of IP subnet masks and the number of hosts that are allowed. Consult your network administrator if you are unsure of this value. IP Subnet Mask 255.255.255.0 255.255.255.128 255.255.255.192 255.255.255.224 255.255.255.255 Number of Host IDs 254 126 62 30 1 Number of Bits 24 25 26 27 32 Before You Begin 17 DI-300/DI-300M Setup and Installation Worksheet *HQHUDO 6HWXS ,QIRUPDWLRQ System Name (for identification purposes): _______________________________________ Protocol(s): ___TCP/IP ___IPX (DI-300M only) ___Bridging (DI-300M only) ,6'1 6HWXS ,QIRUPDWLRQ Switch Type (check one): ___AT&T 5ESS NI-1 ___AT&T Point to Point ___AT&T 5ESS Multipoint ___Northern Telecom NI-1 ___Northern Telecom Custom ___DSS1 ___1TR6 B-Channel Usage (check one): ___Switch/Switch ___Switch/Leased ___Leased/Switch ___Leased/Unused 18 Before You Begin ___Unused/Leased ___Leased/Leased ___Leased128 ___Switch/Unused North American ISDN 1st Telephone Number: _______________________________________ 1st SPID Number: _______________________________________ 2nd Telephone Number: _______________________________________ 2nd SPID Number: _______________________________________ DSS1 ISDN ISDN Data Number & Subaddress: _______________________________________ Outside Line Prefix Number: _______________________________________ PABX Number (S/T Bus Number): _______________________________________ Incoming Number Matching: ___MSN ___Calling Party Subaddress ___Don't Care Before You Begin 19 1TR6 ISDN: ISDN Data Number: _______________________________________ Outside Line Prefix Number: _______________________________________ PABX Number (S/T Bus Number): _______________________________________ Incoming Number Matching: ___EAZ ___Don't Care (WKHUQHW 6HWXS ,QIRUPDWLRQ IP Address: _______._______._______._______ IP Subnet Mask: _______._______._______._______ 1RWHV= 20 Before You Begin Installation This chapter outlines how to connect your DI-300 or DI-300M to your LAN and ISDN line. Refer to the diagram below to identify all of the ports on your device when you make connections. A Warning On Connection Cables The RS-232, ISDN line, and Ethernet cable, are very similar to each other. It is important that you use the correct cable for each connection; otherwise, your router could be damaged. Installation 21 Connecting Your Computer and Your DI-300 or DI-300M For the initial setup of your DI-300 or DI-300M, you must use RS-232 and communications software. After the router has been successfully installed, you can modify the configuration through a remote Telnet connection. See the Telnet Configuration and Capabilities chapter for detailed instructions on using Telnet to configure your DI-300 or DI-300M. Connecting the RS-232 Cable to the Router An RS-232 cable is included in your package. To connect this cable, connect the 9-pin end of the cable to the DCE port on the router's back panel. Connect the other end to the RS-232 cable connected to the serial port (COM1, COM2, or any other COM port) of your computer. Connecting an ISDN Line to the Router Plug one end of your ISDN phone line into the socket on the rear panel of the router labeled ISDN and the other end into the ISDN wall jack. S/T interface--This can only connect to your NT-1 (Network Termination) device. NOTE: Do not under any circumstances connect directly to the ISDN wall jack. 22 Installation U interface--This allows you to connect directly to your ISDN wall jack. NOTE: The ISDN jack is for ISDN line connection only. Connection of a phone line may result in damage to your DI-300 or DI-300M. Connecting an Ethernet Cable to the Router Your DI-300 or DI-300M is equipped with an RJ-45 jack for connection to a 10BASE-T Ethernet or 100BASE-TX Fast Ethernet hub or switch via a standard straight-through twisted-pair cable. Connecting a Power Adapter to the Router Plug a 12V DC, 500 mA power adapter into the jack on the router's side panel labeled POWER At this point, you should have connected the RS-232 cable, the ISDN phone line, the Ethernet cable, and the power supply. You can now power up your DI-300 or DI-300M. The DI-300 or DI-300M's Front Panel Names and descriptions of your router's front panel LEDs are given below: Installation 23 POWER--Comes on as soon as you connect the router to the power supply. TEST--Should be blinking if the router is functioning properly. ISDN: LINK--Indicates that the router has an ISDN line connected to the WAN interface and it has been successfully initialized. ISDN: B1 and B2--On if there is an active WAN session on that channel or if that channel is making or receiving a call. LAN: 10/100--When you connect a network cable to the DI-300 or DI-300M, the router will automatically detect the network speed. The 10/100 LED will light up if the LAN is operating at 100 Mbps. LAN: Link/Act--When the LAN connection is ready but idle, the Link/Act LED will shine steadily. When data are being transmitted or received, this LED will blink off and on. LAN: FDX/COL--The FDX/COL LED will shine green when the LAN connection uses full-duplex signaling. It will flash yellow when the router and another device on the LAN transmit at the same time. Occasional collisions are normal. If collisions are too frequent, the LAN must be reconfigured to reduce traffic loads. Powering Up Your DI-300 or DI-300M When you power up your DI-300 or DI-300M, the router will perform several internal tests and do an ISDN line initialization. 24 Installation After ISDN line initialization, the router will ask you to press ENTER to continue. When you press ENTER, the router will display a login screen and ask you to enter the password, as shown below: Enter the default password, 1234, to get into the Main Menu of the System Management Terminal (SMT). Note that once you are in the SMT and if there is no activity for more than 5 minutes, the router will automatically log you out and display a blank screen. If you see a blank screen, press ENTER to bring up the password screen. Navigating Through the System Management Terminal Interface
