Power Up
(15 minutes)
·
Your modem is now powering up. Wait
for the Power, Ethernet, Broadband,
and Service lights to turn solid green.
(The Activity light will flicker.) This may
take up to 15 minutes.
!
During this time do not unplug the
black Power Adapter or green Data
Cable. This can damage the modem.
·
If the Broadband or Service light does
not turn solid green after 20 minutes
(or has turned red), see the "Having
Trouble?" section later in this guide.
DSL Modem 3360 Quick Start Guide
?
Having Trouble? Many issues can be resolved in three simple steps:
1. Check your connections.
Verify that cables, cords, and filters on all devices are connected properly. Make sure:
• The Dual-Port Filter is plugged into the wall jack (and not the modem).
• The Data Cable is plugged directly into the DSL/HPNA port on the filter.
• Your Phone Cable is connected to the Phone port on the filter.
• You are using the supplied Power Adapter.
Cables usually make an audible "click" when secure. If connections are secure and you have AT&T voice service,
make sure the phone jack has a dial tone. If you are still unable to connect to the Internet, try another phone jack.
2. Power down, power up.
Shut down your computer and unplug the black Power Adapter and any other devices from the back of the modem.
Wait 15 seconds and then plug devices back in, making sure the modem's power light is on. (If the light is not on,
try another power outlet.) Then turn your computer back on.
3. Wait for blinking indicator lights.
Wait for blinking indicator lights to turn solid (may take up to two minutes), and then attempt to access the Internet.
Specific Issues
What if I have a monitored security system or health alarm?
Once you have completed the installation, please contact your alarm
monitoring provider to test your alarm.
What if the Broadband light doesn't turn solid green?
Follow the steps in the "Having Trouble?" section above. If the light
continues to blink, make sure the Dual-Port Filter is plugged directly into the
wall and not the modem.
Why do I need to install filters?
Without filters, you may experience disruptions or hear static on the phone
line. You may purchase additional filters (including wall-mount filters) at att.
com/equipment or most electronics stores.
Note: Filters are not necessary for customers without AT&T voice service.
However, customers in California without AT&T voice service may still have
access to 911 service on their DSL line, and may use filters to reduce the
possibility of static when placing 911 calls.
