Troubleshooting

Problem: 
Telephone on FXS port has no dial tone

Solution: 
1. Ensure that all cables (power, RF, telephone) are properly connected to the 

ESBC. Ensure that ESBC’s AC power adapter is plugged in, and “PWR” 
indicator lights are ON (see Front Cover Picture).

2. Pick up telephone handset (phone off-hook), check for corresponding PHONE 

(1-4) indicator light to be ON. Also, the “ONLINE” indicator light is steady green. 
If not, please disconnect ESBC power cable, and then reconnect it again (see 
Front Cover Picture).

3. If previous steps fail, report the failure to service provider for attention.

Problem: 
Cannot establish Internet connection.

Solution:
1. If the PWR, RECV, SEND, and ONLINE LEDs are solidly lit, the cable modem 

is working properly. Try restarting the computer so that it could reestablish a 
connection with the cable modem.

2. Power cycle the ESBC by switching the power to the Off position, remove 

the power adapter from the electrical outlet and plug it back in. Wait several 
minutes for the cable modem to reestablish communications with your cable 
service provider.

3. If your PC is connected to a hub or gateway, try connecting the PC directly into 

the cable modem.

4. If you are using a cable splitter, try removing the splitter and connect the cable 

modem directly to the cable wall outlet. Wait several minutes for the cable 
modem to reestablish communications with your cable service provider.

5. Your Ethernet or coaxial cable may be damaged. Try using another cable.

6. If none of these suggestions work, contact your cable service provider for 

further assistance.
