1 — ONT and MDU overview
1.6 ONT configuration using a web-based interface
Some Package C ONTs support additional limited configuration using web-based
GUIs not included in section 1.5. By using the provided GUIs, the customer can
perform the following configuration and reporting tasks:
•
Network (including LAN, WAN, and Wi-Fi service configuration)
•
Advanced (including SNTP, DDNS, Port forwarding, and Firewall
configuration)
•
Maintenance (including password change, revert to factory default, reboot
device, and upgrade tasks)
•
Status (including the display of device info, WAN status, and PON Statistics
information)
The Package C ONT that supports limited configuration using web-based GUIs is the
I-241W-P indoor ONT.
1.7 ONT physical security
Physical ONT security is provided to limit unauthorized access to remote or outdoor
units. Tamper-resistant seals and bolts are used to secure the TELCO access cover to
the ONT and to prevent easy access to the enclosure. Specialized security wrenches
are required to open the pin-in Allen-type tamper-resistant screws. Certain models of
indoor ONTs cannot be opened.
1.8 Rogue ONT defense
Fault or error conditions on a single ONT may disrupt the PON for other ONTs on
the same PON. Figure
