Quick Start
for the
Cisco 678 ADSL Router

Introduction

The Cisco 678 is an asymmetric digital subscriber line (ADSL) router that provides home connectivity to an ADSL service provider (SP) network over an ADSL/ATM physical layer. The Cisco 678 ADSL router receives and transmits at rates up to the following adaptive rates:

The Cisco 678 ADSL router uses the Cisco Broadband Operating System (CBOS).

System Requirements

This list defines the hardware and software requirements necessary to install and configure the Cisco 678:

• Personal computer (either standalone or on a network)
  
  
• Terminal emulation application
  
  
• DB-9 serial port
  
  

Note If only a DB-25 serial port is available on the computer, you must also use a DB-9-male-to-DB-25-female adapter to connect the serial cable to the computer.

• Ethernet port or adapter, or a connection to the immediate local area network (LAN)
  
  

Installing the Cisco 678

This section provides basic information necessary to install the Cisco 678. Refer to Chapter 2 of the Cisco 678 ADSL Router Installation and Operation Manual for detailed installation instructions and illustrations.

Connecting the Cables

To connect the cables:

Step 1   Plug the power connector into the back of the unit.

Step 2   Connect the Ethernet cable to the ENET connector.

Step 3   If the computer at the customer premises has only a single Ethernet-equipped computer, attach the Cisco 678 to the computer's Ethernet adapter with the crossover cable provided. Otherwise, connect the Cisco 678 Ethernet port to an Ethernet hub using a straight-through cable.

Step 4   Connect the provided telephone cable to the Cisco 678 WALL connector and then connect the other end of the cable to the wall-mounted telephone connector.

Step 5   (Optional) Plug the microfilter into the PHONE connector, and plug the telephone into the microfilter.

Note Never connect a telephone directly to the PHONE connector as this affects the Cisco 678 performance.

POTS Splitter Configuration

A POTS splitter separates data signals from voice signals on your telephone line. The POTS splitter works by running a separate data line from the voice line, so that the Cisco 678 has a dedicated cable for data transmission.

The Cisco 678 ADSL Router Installation and Operation Guide shows a POTS splitter configuration. If you are using an external POTS splitter, connect the provided telephone cable to the wall connector that is labeled as going to the external POTS splitter.

Note Contact your SP if you have questions regarding your configuration.

EZ-DSL™ (Splitterless) Configuration

In the EZ-DSL configuration, your telephone equipment is not connected to a POTS splitter. Without a POTS splitter and under certain circumstances, transient noise from the telephone can interfere with the operation of the Cisco 678, and the Cisco 678 can cause noise on the telephone line. To prevent this from happening, connect small microfilters to the telephone lines as shown in the Cisco 678 ADSL Router Installation and Operation Guide.

Figure 2-5 in the Cisco 678 ADSL Router Installation and Operation Guide shows a splitterless configuration. Make sure there is a microfilter connected to the line of each telephone that connects to your network.

Installing the EZ-DSL Microfilter

Use EZ-DSL microfilters to connect telephones at the customer premises to the premises telephone wiring. The microfilters are designed to prevent interference between the Cisco 678 and the telephone set, as well as to reduce the effect of POTS-generated noise on the ADSL transceiver.

Step 1   Identify all home telephones plugged in and in service. Install an EZ-DSL microfilter at each home telephone.

Step 2   Unplug the telephone from the wall. Plug the telephone cord into the end of the EZ-DSL microfilter marked PHONE.

Step 3   Using the 3-inch telephone cord provided, plug one end of the cord into the microfilter marked WALL. Plug the other end of the cord into the telephone wall receptacle.

Step 4   After you complete the installation, verify that your telephone service works. If your telephone service does not work, disconnect the EZ-DSL microfilter and contact your local telephone company or Cisco Systems.

Note The microfilters do not function if connected incorrectly. To ensure that the microfilters function, connect the wall side of the microfilter to the wall jack and the telephone side of the microfilter to the telephone.

Configuring the Cisco 678

Having completed all the above procedures, you have now successfully installed your Cisco 678 and are ready to begin your configuration.

Your configuration requirements will vary depending on your SP. Contact your SP for detailed information regarding how to configure your Cisco 678 for optimal performance.

Troubleshooting Tips

If the suggested course of action does not resolve your issue, contact your SP. For detailed information, refer to Chapter 4 of the Cisco 678 ADSL Router Installation and Operation Guide.

• If the WAN LNK LED blinks continuously and fails to achieve a solid state within a minute, your Cisco 678 configuration might not be compatible with the SP's server configuration.
  
  

  Solution: Remove power from the Cisco 678 by removing the power cord from the router's rear panel. Reconnect the power cord and check all cables, especially the WALL cable. If your router still does not connect to the SP, call your SP. Your SP can assist you to correct your configuration.

• If the WAN LNK LED turns off after the Cisco 678 has successfully been transferring data between your PC and your SP, the Cisco 678 or the SP's server might have a timeout set.
  
  

  Solution: Call your SP and provide an estimate of the time (be as accurate as possible) that you remain connected before the Cisco 678 disconnects from the Internet.

• If the WAN LNK LED turns on solid for approximately four seconds and then turns off and remains off, this might indicate a user authentication failure. Either your Cisco 678 or your SP's server might contain incorrect user authentication information.
  
  

  Solution: Call your SP with the amount of time it took before the WAN LNK LED turned off.
