Step 1: Connecting your modem to the serial port

To configure your DSL modem you first have to connect it to the serial port on your computer. The Cisco 678 comes with a special serial cable to connect the serial port of a computer to the Cisco  678 management port. You can get detailed instructions on how to  do this from your US West DSL manual, or follow the diagram below. On a Apple, an adapter cable  is required. If the connection doesn't work using the Mac serial port, try the parallel port.

Step 2: Setting up Hyper Terminal

Now that your Sisco 678 is connected to the serial port, we'll  need to configure the Sisco 678 using Hyper Terminal. Do this by clicking 'Start' => 'Programs' => 'Accessories' => 'Hyper  Terminal'. Once Hyper Terminal is active, you'll get a window that  looks something like the one below.

Double click on Hypertrm.exe, and follow the steps to configure  your connection.

• Enter any name for the connection and click the 'OK' button
• Leave the phone number blank, and in the connect using field select 'Direct to com1'(Like below). You can Also try  'Direct to com 2' if com one does not work.
• Click the 'OK' button.

This will bring up the COM1 (or COM 2) properties window. Follow these steps to make sure that everything looks the same as below.

• Bits per second set to '38400'
• Data bits set to '8'
• Parity set to 'None'
• Stop bits set to '1'
• Flow control set to 'None'
• Click 'OK'

You should now see a blank Hyper Terminal screen, where you will type a series of commands to configure your modem. It is extremely crucial that you follow these steps exactly. The key below is used used only for clarity's sake. (The commands  you type will be in bold.

Hit enter until you see the following  cbos prompt. Then type the following commands.
