at the common mounting platform.
complete the following tests:
■ POTS tests described in
■ Ensure Provisioning of the ONT at the OLT has been completed. For the provisioned
Ethernet link, use external equipment (for example, a laptop computer) to verify the
Ethernet link is active. Verify the OLT can run and pass the loop-back tests for the
Ethernet port.
If the above tests are successful, the indication of the trouble is directed back toward the
CPE wiring/equipment.
