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.
