Finally I was able to find one PLDT Fiberhome ONU HG6245D around the NCR area, the good thing is that the firmware is still unchanged its RP2602 so the default Super Admin username and password for the graphical user interface (GUI) is widely known no need to guess. How about adminpldt user account and password? Its by default you can just find it on this blog its identical to AN5506-04-FA/T there's no need to worry.
Looking at the menus I can see no difference with RP2627 and RP2631 of AN55-0406-FA but except of the IPTV sub-menu is already revealing.
Another sub-menu we can see under the Network Menu is the VoIP Settings, this will remind us that it would be possible for us to replicate the VoIP settings and make our own relay server and use a soft phone.
On the hardware side it is also an ARMv7 Processor but Broadcom chips only a single core.

We will wait this ONU if the updates takes place will visit again to see if the CLI will most like the AN5506-04-FA/T.
