FTTH Application Guide

Summary

All the applications described may be done in sequence as shown in the

flowchart.

There must be synchronization between the OMCI profiles (particularly

regarding GEM ports and VLAN).

By activating the ONT you can add it to the system. If you are adding multiple

services, you would activate the ONT after all the services have been added.

If the OMCI profiles are configured, you may add other bridges without

resetting the ONT. If you changed OMCI profiles you will need to resent the

ONT.

Troubleshooting

This section is basically what can go wrong, how to recognize and understand

what went wrong, and how to fix it.

Symptom Discussion

You can see power LED

is green on the ONT,

but operational LED is

red. And ONT

OperStatus appears as

Down when you use the

gpononu status

command.

This symptom shows the fiber connection might be

loose or disconnected. Check the fiber connection on

ONT, splitter, and MXK.

You can see a MAC

address of the

downstream laptop, but

do not get the IP

address.

This symptom actually happened when setting up the

scenario. It is significant to note that with an

uplink-downlink bridge as we have created in this

scenario, addresses will not be learned until the

downstream device sends a packet to the MXK.

To rectify the situation we deleted the bridge and added

it again this time with the downlink parameter.

It is also possible that you do not have a DHCP server

upstream from the MXK. The DHCP upstream from

the MXK is a requirement of this scenario.

And also make sure the VLAN you assigned is a

routable VLAN.
