Provision Ethernet Interface at OLT

Provision and unlock the Ethernet port to be used at the OLT. For the provisioned Ethernet
link, use external equipment (for example, a laptop computer) to verify the Ethernet link is
active.

Troubleshooting

Consider the following two principles when troubleshooting a SBU ONT unit:
• Because voice and data signals originate at the OLT equipment, a failure of all services
• The OLT has diagnostic testing procedures that can monitor the status of every SBU ONT
NOTE
The home telephone wires are connected using pivot connectors, and the RJ-
11 jack serves as a test access point. In this configuration, inserting a
telephone cable into the RJ-11 jack will disconnect the SBU ONT from home
wiring and connect the SBU ONT to the inserted cable instead. This allows
the home owner or service provider to diagnose SBU ONT or home wiring
related problems. Inserting an RJ-11 jack (such as a telephone cable or
telephone test set) into the connector, will connect the telephone set and also
disconnect the subscriber service from the SBU ONT. Hence fault may be
isolated to the SBU ONT or premises wiring.

WARNING
• Do not look into the ends of optical fibers. Exposure to invisible LASER
radiation may cause serious retinal damage or even blindness. Verify the
optical source is disabled through the use of an optical power meter before
handling optical fibers.
• This equipment must be connected to a known good earth ground at all
times during service. Refer to the National Electrical Code (NEC) and
state/local codes for details on grounding requirements.
