Troubleshooting

The analog modem does not dial my cable company’s server 
properly.

Make sure that the power supplies for both the analog 
modem and the TMX are plugged into electrical outlets 
and make sure the analog modem is turned on.

Make sure your phone line is active. Plug a telephone 
into the analog phone jack and listen for a dial tone.

Make sure there are no devices between the analog 
modem and the phone jack.

If you have voice mail, there may be messages waiting 
for you, altering the dial tone. Answer any messages to 
return the dial tone to normal.

Make sure you are dialing the correct access number for 
your cable company’s cable modem service.

Make sure the telephone cord is plugged into the 
analog modem you have connected to the TMX.

My computer went into “power save” mode. When it came 
out of power save mode, my screen was frozen.

If the upstream (analog modem) connection is active when 
a computer goes into power save mode, the computer may 
freeze when coming out of power save mode. Either hang 
up the analog modem before your computer goes into 
power save mode or disable power save on your PC. If you 
choose to disable power save, disable it in both the 
Windows 95 Control Panel and the BIOS setup. To disable 
power save in Windows 95, click Windows 95 

Start

, point 

to 

Settings

, and click 

Control Panel

. Double-click the 

Power

 icon and select 

OFF

 in the “Power Management” 

box. Click 

Apply

. To disable power save in the BIOS setup, 

you usually must press a function key while booting up to
