Enabling Fec; Configuring An Onu To Report Information To The Olt; Configuring Traffic Encryption - 3Com S7906E Configuration Manual

Enabling FEC

Forward Error Correction (FEC) can implement downlink error correction on the OLT and uplink error
correction on the ONU to lower the bit error rate and extend the optical transmission distance. The
packets enabled with FEC carry error correction codes. Therefore, the actual uplink bandwidth of the
ONU will be less than that configured.
Follow these steps to enable FEC:
To do...
Enter system view
Enter ONU port view
Enable the FEC function

Configuring an ONU to Report Information to the OLT

When an ONU attached to an OLT encounters configuration changes or failures or is being debugged,
you can configure the ONU to report the specified types of information to the OLT.
Note that:
Because a large number of ONUs are attached to an OLT, enabling ONUs to report information to the
OLT may generate a large amount of traffic and thus cause congestion. Therefore, you are
recommended to select the reported information type as required.
Follow these steps to configure an ONU to report information to the OLT:
To do...
Enter system view
Enter ONU port view
Configure the ONU to report
the specified types of
information to the OLT

Configuring Traffic Encryption

Complete this task to configure the encryption of the downlink traffic transmitted from the OLT to ONUs,
thereby protecting user information against illegal access.
Follow these steps to configure traffic encryption:
To do...
Enter system view
Enter ONU port view
Use the command...
system-view
interface onu
interface-number
forward-error-correction
enable
Use the command...
system-view
interface onu
interface-number
onu-event { debug | log |
trap } enable level severity
Use the command...
system-view
interface onu
interface-number
3-13
