`
`
`Introduction
`
`Congratulations on your purchase of a TRENDnet TW-H6W1IR
`ISDN router with integrated Ethernet hub and ISDN T/A. 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 everything from Internet browsing to
`receiving calls from Remote Dial-in Users and making connections to
`other LANs via Remote Nodes.
`
`Distinguishing features of the TW-H6W1IR include support for a full
`range of networking protocols including TCP/IP (Transmission Control
`Protocol/Internet Protocol, also known as IP) and Transparent
`Bridging.
`
`This complete solution also includes remote dial-in user support, an
`Internet single-user account (Network Address Translation) option,
`extensive network management capabilities, and solid security features.
`
`Introduction

`

`

`TW-H6W1IR ISDN Remote Router
`
`Product Features
`
`The TW-H6W1IR 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.
`
`Ease of Installation
`
`Your TW-H6W1IR 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 10 Mbps Ethernet hub, and it uses
`twisted-pair Ethernet cables to connect to the host network.
`
`Built-in Hub
`
`As a 10 Mbps Ethernet hub, your TW-H6W1IR provides six ports for
`connecting standard Ethernet devices. Five ports are designed for
`connecting network end nodes—single-user computers, servers,
`bridges, other routers, etc.—through standard “straight-through”
`twisted-pair cables; the sixth is wired for making an “uplink” connection
`to another hub or switch through the same type of straight-through
`cable used to connect end nodes.
`
`ISDN Basic Rate Interface (BRI)
`
`Using a standard S/T the TW-H6W1IR 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-on-demand.

`
`Introduction
`
`

`

`TW-H6W1IR ISDN Remote Router
`
`
`ISDN Leased Line
`
`If the router is set up for an ISDN leased line, it can automatically
`initialize the leased-line connection each time it is powered up.
`
`Standard Phone Jacks
`
`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 TW-H6W1IR 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
`
`Your TW-H6W1IR supports bandwidth up to 128 kps over a single
`ISDN BRI line. It incorporates MLPPP (Multi-Link PPP) 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 the multi-link bundle.
`
`Full Network Management
`
`The TW-H6W1IR incorporates SNMP (Simple Network
`Management Protocol) support and menu-driven network management
`via an RS-232 or Telnet connection.
`

`
`

`

`TW-H6W1IR ISDN Remote Router
`
`RADIUS (Remote Authentication Dial In User Service)
`
`The RADIUS feature allows you to use a central external Unix or NT-
`based server to support thousands of users.
`
`PPP Security
`
`The TW-H6W1IR supports PAP (Password Authentication Protocol)
`and CHAP (Challenge Handshake Authentication Protocol).
`
`RIP-1/RIP-2
`
`Your TW-H6W1IR supports both RIP-1 and RIP-2 (Routing
`Information Protocol versions 1 and 2) exchanges with other 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.
`
`Data Compression
`
`The TW-H6W1IR incorporates Stac data compression and CCP
`(Compression Control Protocol).
`
`Networking Compatibility
`
`The TW-H6W1IR is 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.

`
`
`Applications for your TW-H6W1IR
`
`Some applications for the TW-H6W1IR include:
`
`Internet Access
`
`Your TW-H6W1IR 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 TW-H6W1IR 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 TW-H6W1IR can dial to or answer calls from another remote
`access router connected to a different LAN. The TW-H6W1IR
`supports TCP/IP and has the capability to bridge any Ethernet
`protocol.
`
`Telecommuting Server
`
`The TW-H6W1IR allows Remote Dial-in Users to dial in and gain
`access to your LAN. This feature enables users that have workstations

`
`Telephone Features
`
`Up to two telephones can be attached to the TW-H6W1IR router via
`the Phone 1 and Phone 2 telephone jacks located on the rear of the
`router. The router enables the attached telephones to have a number of
`features which may or may not be found on normal telephones and are
`described below. Additional features which must actually be configured
`are described in the Interface Configuration – ISDN Sub-menu
`section of this manual.
`? ? Hold – This feature is very similar with and can work in conjunction
`with call waiting as defined in the Interface Configuration – ISDN
`Sub-menu section of this manual. Press Flash 0 to place someone
`on hold (Flash is a very brief hanging up of the phone). Press Flash
`2 to take the caller off hold.
`? ? Hold (and pick up from another location) - Telephones
`connected to the router can be put on hold by pressing Flash 71,
`72, 73, or 74. Press the same number to take the caller off hold
`and speak from another phone on your telephone network.
`? ? Call forwarding – If you wish to forward incoming calls to a
`different telephone, press *77* and then the phone number you
`wish to forward the call to. All incoming calls will automatically be

`
`forwarded to the phone number entered. Press #77# to cancel call
`forwarding.
`? ? Three-person conference call – To use this feature, conference
`calling must be enabled by the telephone company. After this is
`done, pick up a phone and place a call. After connected, press
`Flash 0 (refer to call waiting in the Interface Configuration –
`ISDN Sub-menu section of this manual) and dial the second
`number. After connected, press flash 3 to speak to both parties at
`the same time. Press Flash 0 to hang up with the first party called.
`Press flash 1 to hang up with the second party called.
`? ? Call transfer – To transfer a call to the other phone jack on the
`router: if using Phone 1, press flash 20. If using Phone 2, press flash
`10.
`
`Installation and Initial Configuration
`
`This section discusses the different connections that can be made to the
`router when setting it up.
`
`Initially, you will only wish to connect the console to the router in order
`to configure the other ports. Once that is complete, you will need to
`turn off the power to the router and plug in the connection cables to the
`other devices. Next, power on the other devices. When they have
`finished powering up, power on the router. Each of these steps is
`described in detail in the sections below. Please skip any setting
`adjustments that do not apply to your configuration needs.
`
`14
`
`Installation
`
`

`

`TW-H6W1IR ISDN Remote Router
`
`
`For the initial configuration of your TW-H6W1IR, you must use an
`RS-232 console connection, either to a computer running serial
`communications software or to a serial data terminal.
`
`After the router has been successfully installed and the initial
`configuration is complete, you can continue to modify settings through
`the console, or you can change configuration settings through a remote
`Telnet connection or through a web browser. See the chapters entitled
`Configuration and Management and Using Telnet for detailed
`instructions on using Telnet to configure your TW-H6W1IR.
`
`A Warning on Connection Cables
`
`ISDN and Ethernet cables are very similar to each other. It is important
`that you use the correct cable for each connection; otherwise, your
`router could be damaged.
`
`Before connecting or disconnecting an RS-232 cable between two
`devices, turn both devices off to avoid any chance of damaging them.
`
`Step 1 - Setting up the Console
`
`The initial setup of the TW-H6W1IR, requires connecting a console
`to the 9-pin RS-232 Diagnostic port on the router’s rear panel. A
`serial cable is supplied with the router in order to make this
`connection. A console can be a terminal, such as a VT-100, or a
`normal PC running terminal emulation software (such as Microsoft
`HyperTerminal, included with Windows). The terminal emulation
`software needs to be configured to the following parameters:
`?? VT100 terminal emulation
`
`Installation
`
`15
`
`

`

`TW-H6W1IR ISDN Remote Router
`
`?? 9600 baud
`?? No parity, 8 data bits, 1 start bit, 1 stop bit
`?? No flow control
`
`Step 2 - Connecting the Console to the Router
`
`A serial cable is included in the TW-H6W1IR package. To connect
`this cable, plug its nine-pin connector into the 9-pin RS-232 Diagnostic
`port on the router’s rear panel, then connect the other end to the serial
`port on the rear of your computer or data terminal.
`
`Please make sure both machines are turned off before making this
`connection.
`
`After the connection is made, first power on the console. If you are
`using a PC, run the terminal emulation software at this time. After the
`PC and the terminal emulation software are up and running, power on
`the router.
`
`Using the Console
`
`The Console Program is the interface that you will be using to
`configure your TW-H6W1IR. Several operations that you should be
`familiar with before you attempt to modify the configuration of your
`router are listed below:
`? ?Moving the Cursor. Within a menu, use Tab and arrow keys
`to navigate through different information fields.
`? ?Moving Forward to Another Menu. To move forward to a
`sub-menu below the current one, use Tab or arrow keys to
`
`16
`
`Installation
`
`

`

`TW-H6W1IR ISDN Remote Router
`
`
`position the cursor on the sub-menu item and press Enter to
`view the selected sub-menu.
`? ?Entering Information. There are two types of fields that you
`will need to fill in. The first requires you to type in the appropriate
`information. The second gives you choices to choose from. In the
`second case, press the space bar to cycle through the available
`choices. Upon configuring all fields the sub-menu, position the
`cursor on SAVE and press Enter to save, or position the cursor
`on EXIT to cancel.
`? ?Refresh Screen. Console screens are notorious for becoming
`garbled. When this happens, simply press <Ctrl> + <R> to
`refresh the contents of the screen.
`
`Step 3 - Connecting an ISDN Line to the Router
`
`Your phone company will provide an S/T interface into your home or
`office. Plug the ISDN line from the router directly into the ISDN wall
`socket provided by your phone company.
`
`Step 4 - Connecting a Telephone or Fax Machine to the Router
`
`You can connect a regular telephone, fax machine, or modem to your
`router to be used for analog calls. Note that the router’s other functions
`all work the same whether you connect an analog device or not.
`
`To connect an analog device, just plug one end of the device’s cord
`into one of the sockets on the back of the router marked PHONE 1 or
`PHONE 2.

`TW-H6W1IR ISDN Remote Router
`
`To have incoming calls directed to a device on a PHONE jack, you
`must enter the telephone number for the phone in the console program
`under the Interface Configuration, ISDN submenu.
`
`Step 5 - Connecting Ethernet Cables to the Router
`
`Your TW-H6W1IR has six ports for connecting 10BASE-T Ethernet
`devices to form a LAN. The jacks for ports 1 through 5 are wired to let
`you connect network end nodes (computers, servers, bridges, other
`routers, etc.) using standard “straight-through” EIA (Electronic
`Industries Association) Category 3 or higher twisted-pair cables. The
`jack for the sixth port is labeled Uplink and is wired to let you connect
`to another 10Mbps Ethernet or dual-speed hub using a straight-through
`cable, or an end node using a cross-wired cable.
`
`Please refer to the following chart when deciding on the type of cable
`necessary for a given connection:
