Installing the Cisco 676 ADSL Router
The following sectio ns will pr ovide the in format ion necess ary to ins tall the
Cisco 676 ADSL Router. Please refer to Chapter 2 of the
Cisco 676 ADSL
Router Installation and Configuration Manual
for detailed installation
instructions and procedure illustrations.
Connecting the Cables
Figure 2-7 in the “
Cisco 676 ADSL Router Installation and Operation
Manual
” shows where to connect all cables to the rear panel connectors of
the Cisco 676 ADSL Router.
Step 1
Plug the power connector into the back of the unit.
Step 2
Connect the Ethernet cable to the Cisco 676 ENET connector.
Step 3
If the computer at the customer premise has only a single
Ethernet-equipped computer, attach the Cisco 676 to the
computer’ s Ethe rn et ad apter wit h the cr osso v er cabl e pro vi ded.
Otherwise, connec t the Cisco 6 76’s Ethernet port to an Ethe rn et
hub using a straight-through cable.
Step 4
Connect the provided telephone cable to the Cisco 676 WALL
connector and then connect the other end of the cable to the
telephone wall-mounted connector.
The POTS Splitter Configuration
A POTS splitter separates data sign als from voice sign als on your phone
line. The POTS spl itter works by ru nning a separate data line from the voice
line, so that the AD SL mod em has a d edi cated cabl e fo r data tra nsm iss ion .
Figure 2-4 in the
Cisco 676 ADSL Router Installation and Operation
Manual
shows a POTS splitter configuration. If you are using an external
POTS splitter, connect the provided telephone cable to the wall connector
that is labelled as going to the external POTS splitter.
Note: Contact your s erv ice pr ovider if you have questions regarding you r
configur a tion.

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. Fi gur e 2 -6 in the
Cisco 676 AD SL R ou ter I ns t allation and O peration
Manual
shows a splitterless configuration. Make sure there is a micr of i lter
connected to the line of each telephone that connects to your network.
Installing the EZ-DSLTM Microfilter
Use EZ-DSL microfilters to connect ph ones at the customer premise to the
premise phone wi ring. The microf ilters are designed to pre vent i nterf erence
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 mic rofil ter should be inst alled a t eac h home te lephone .
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 micr o f ilters function, conn ect th e wall side of the micr ofilter 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.
1
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 pow er from th e Cisco 67 6 ADSL Router by
removing the power cord from the router’s rear panel. Reconnect the
power cord. If yo ur router still do es not co nnect t o the servi ce provi der ,
call your service provider. Your service provider can assist you to
correct your configuration.
2
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 pro vider with as close to an exact len gth of
time as possible you remain connected before the 676 disconnects
from the Internet.
3
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.
