EZ-DSL (Splitterless) Configuration

In the EZ-DSL configuration, your phone equipment is not connected to a

POTS splitter. Without a POTS Splitter and under certain circumstances,

transient noise from the phone can interfere with the modem's operation,

and the modem can cause noise on the phone line.

To protect this from happening, connect small microfilters to the phone

lines. Figure 2-6 in the Cisco 676 ADSL Router Installation and Operation

Manual 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 phones at the customer premise to the

premise phone wiring. The microfilters are designed to prevent interference

between the modem and the phone 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. An

EZ-DSL microfilter should be installed 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 676 ADSL Router

Having completed all the above procedures, you have now successfully

installed your Cisco 676 ADSL Router and are ready to begin your

configuration.

Your configuration requirements will vary depending upon who your

service provider is. Contact your Internet Service provider for detailed

information regarding how to configure your Cisco ADSL 676 Router for

optimal performance.

Troubleshooting Tips

The following are troubleshooting tips. If the suggested course of action

does not resolve your issue, contact your Internet Service Provider. For

detailed information, refer to Chapter 4 of the Cisco 676 ADSL Router

Installation and Operation Manual.

If the WAN LNK LED blinks continuously and never stays solid on,

the 676 never connects to the service provider equipment. Your Cisco

ADSL 676 Router configuration may not be compatible with the

service provider's server configuration.

Solution: Remove power from the Cisco 676 ADSL Router by

removing the power cord from the router's rear panel. Reconnect the

power cord. If your router still does not connect to the service provider,

call your service provider. Your service provider can assist you to

correct your configuration.

If the WAN LNK LED turns off after the 676 has successfully been

transferring data between your personal computer and your service

provider, the 676 or the service provider's server may have a timeout

set.

Solution: Call your service provider with as close to an exact length of

time as possible you remain connected before the 676 disconnects

from the Internet.

If the WAN LNK LED turns on solid for approximately four seconds

and then turns off and remains off, this may indicate a user

authentication failure. Either your Cisco ADSL 676 Router or your

service provider's server may contain incorrect user authentication

information.

Solution: Call your service provider with the amount of time it took

before the WAN LNK LED turned off.
