Troubleshooting
Problem:
Telephone on FXS port has no dial tone
Solution:
1. Ensure that all cables (power, Ethernet, 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 “WAN” indicator light is
Blinking Amber. 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, WAN, and LAN LEDs are lit, the ESBC 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 ESBC 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 ESBC.
4. Your Ethernet cable may be damaged. Try using another cable.
5. If none of these suggestions work, contact your cable service
provider for further assistance.
