Connect your PC or hub to the LAN port: • Use the red crossover cable included to connect the router directly to a PC. • Use the white straight-through cable included to connect the router to a 10 Mbps or 100 Mbps hub or switch port. The router will sense the speed of the connected port and will automatically set its speed to match. Note: If you are using a 100 Mbps Fast Ethernet network or a mixed 10 Mbps/100 Mbps network, use Category 5 cabling (included). Model RT338 ISDN Router Installation Guide 2. Connect the analog devices to the phone ports (Phone 1 and Phone 2, respectively). 3. Connect the ISDN line from the router to the ISDN wall connection. Use the black cable that is provided. 4. Connect a network manager workstation to the RS-232 port. This step is optional. 5. Connect the DC power adapter cable to the power outlet on the rear panel of the switch and plug the power adapter into the wall outlet. Prepare the Router Do the following to prepare your router: • Order ISDN service from the phone company. • Configure your PC to use the TCP/IP networking protocol. • Order Internet service from an Internet service provider (ISP). The following section provides an overview of the requirements. Ordering an ISDN Line Contact the ISDN sales center of the phone company and order an ISDN Basic Rate Interface (BRI) phone line. In North America, provide the phone company with an ISDN ordering code (IOC). NETGEAR recommends codes IOC “U” or EZ-ISDN1 for the Model RT338 router. Additional information about ordering an ISDN line can be found in the Model RT338 ISDN Router Installation Guide. When the ISDN line is installed, make sure you have the following information: • ISDN directory number(s) • Service profile identifier numbers (SPIDs) (North America only) • Switch type and protocol of the switch (such as National ISDN NI-1) used at the telephone company (North America only) Order any additional ISDN or phone service at this time. Setting up Your Network The Model RT338 router uses the Internet Protocol (IP). To access the Internet using the Model RT338 router, all PCs must have TCP/IP installed and selected as their networking protocol. TCP/IP is built into Windows® 95, Windows 98, and Windows NT® but must be enabled and configured. Refer to “Configuring TCP/IP Properties” for instructions to install IP networking. In an IP network, all PCs must be assigned IP addresses. Most LANs use private IP addresses. These addresses are assigned automatically by the Model RT338 router whenever a PC reboots. Refer to “Using Private IP Addresses” for instructions to use private IP addressing. Model RT338 ISDN Router Installation Guide All PCs must also have other IP configuration information, including a subnet mask, a domain name server (DNS) address, and a default gateway address. This information is also assigned automatically by the Model RT338 router whenever a PC reboots. For mor...
