If any items you ordered were not delivered, please contact Cisco or your service provider. Refer to "Cisco 678 Connectors" for information on connector pin assignments.

Hardware Requirements

The following hardware is necessary to configure and use the Cisco 678:

Setting Up the Cisco 678 Hardware Environment

This section describes how to connect and configure the Cisco 678 ADSL router.

Connect the Management Port to the Serial Port

Follow these steps:

Step 1 Connect the RJ-45 connector on the serial cable to the Cisco 678 management port. (See Figure 2-2.)

Step 2 Connect the other end of the serial cable to the computer serial port. If your computer is equipped only with a DB-25 serial port, you need a DB-9-male-to-DB-25-female adapter.

Step 3 Use the terminal emulation program from your PC's operating system to access the Cisco 678.

Step 4 Log in to the Cisco Broadband Operating System (CBOS) as outlined in "Log On to the Cisco Broadband Operating System" section.

Configure the Serial Port

For the best access to the CBOS, use your terminal emulation program (such as HyperTerminal in Windows) to set your COM protocol to the following settings:

Connect All Cables to the Network

The procedure for connecting cables differs depending on whether or not your telephone equipment is connected to a POTS splitter.

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 ADSL router has a dedicated cable for data transmission. Figure 2-3 shows telephone equipment connected to a POTS splitter. In Figure 2-3 and Figure 2-4, the PHONE port cannot be used. Figure 2-6 shows how to connect all cables to the Cisco 678 ADSL router.


Figure 2-3: Cisco 678 Connected through an Internal POTS Splitter


Note The POTS splitter can also be installed adjacent to the telephone network interface device (NID) on the outside of the house . Figure 2-6 shows how to connect all cables to the Cisco 678.

Figure 2-4 shows how to connect a Cisco 678 when using an external POTS splitter.

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 a telephone can interfere with the router's operation, and the router can cause noise on the telephone line. To prevent this from happening, small microfilters must be connected to the telephone lines. If you implement an EZ-DSL configuration, your installation landscape should look similar to Figure 2-5.


Figure 2-5: Splitterless Configuration


Note The microfilters do not work if connected improperly. For connection instructions, see "EZ-DSL Microfilter Specifications."

Figure 2-6 shows how to connect the cables to the Cisco 678 ADSL router.


Figure 2-6: Rear Panel Cabling Diagram


Complete the following steps to connect the cables to the Cisco 678 ADSL router:

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

Step 2 Connect the Ethernet cable.

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 via a straight-through cable.

Step 3 Connect the ADSL cable to the Cisco 678 and then connect the Cisco 678 to the ADSL line with the telephone cable provided.

Step 4 (Optional) Plug the microfilter into the phone port, then plug the telephone into the microfilter.

Note Never connect a telephone directly to the phone port as this affects the Cisco 678 performance.

Power On the Cisco 678

Step 1 Connect power to the Cisco 678 by plugging the power supply into an appropriate electrical outlet.

Note Use only the Cisco-approved power supply that shipped with the Cisco 678 as your power supply.

Step 2 When you have powered up the Cisco 678, check that the Power LED is ON.

Step 3 If the Power LED is not lit, immediately remove the barrel power connector from the Cisco 678. Refer to "Troubleshooting," for information.

Note To power down the Cisco 678, unplug the power supply cable from the Cisco 678 rear panel PWR connector.

Warnings and Cautions

Warning To prevent dangerous overloading of the power circuit, read the label on the rear of the Cisco 678 that indicates maximum power load ratings. Failure to follow these rating guidelines could result in a dangerous situation.
Warning Do not use this product near water; for example, near a bath tub, wash bowl, kitchen sink or laundry tub, in a wet basement, or near a swimming pool.
Warning Never install telephone wiring during an electrical storm.
Warning Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Warning Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
Caution Use caution when installing or modifying telephone lines.
Warning Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of electric shock from lightning.
Warning  Do not use a telephone to report a gas leak in the vicinity of the leak.
