The ISP’s custom firmware either hides or disables the DNS configuration fields. This is often done to force subscribers to use the ISP’s own DNS servers (which may block certain websites or perform filtering).
The software capabilities are closely tied to the hardware infrastructure of the Titanium 2122A ONT . The firmware regulates the following key hardware specs:
Perform a hard hardware reset. Press and hold the pinhole button on the back for 15 seconds while the unit is on. Advanced Configuration: Bridge Mode and OpenWrt
