2Check that the:

•Termination system and termination adapter have the same privacy key. Unmatched privacy keys make it impossible for termination adapters to send/receive data to/from the termination system. (The Web Configurator EP Management screen shows a red background for unmatched termination adapters.)

•Host limit for each termination adapter is not zero. If the host limit of the termination adapter is 0 (zero) or the IN port is disabled, the termination adapter is not allowed to send/receive data.

•IN port for each termination adapter is not disabled.

3Check the physical connection quality between the termination system and each termination adapter by diagnosis tools.

4If the connection quality is not good enough, please review the whole coax segment.

•Check the wiring topology does not have amplifiers.

•Check the total path attenuation, including mixers, combiners, splitters and taps.

•Check for noise sources.

5Check the firmware version of the termination system and termination adapters.

I cannot transmit/receive data between termination adapters.

For security, termination adapters can’t communicate directly with each other.

I cannot reach high speed communication.

1Check the bandwidth control settings, or the maximal throughput of your WAN service.

2Check your physical connection quality.

13.4Resetting the EOC350-TS to Factory Defaults

If you reset the EOC350-TS, you lose all of the changes you have made. The EOC350-TS re-loads its default settings, and the username/password resets to admin/1234. You have to make all of your changes again.

You will lose all of your changes when you reset the EOC350-TS to its factory defaults.

To reset the EOC350-TS,

1Make sure the power LED is on.
