When set as FTTH does the WAN port work on an unprovisioned device?
I do not, currently, have an answer.
The un-provisioned HHG2500 in my possession has never been connected via the xDSL port nor the EWAN port. Remembering that I do not have a service provided over a G.993.2 metallic pathway, what would be an appropriate test to answer your query?
I could, for example, attach a Huawei SmartAX MT882 to the incoming line, with the MT882 configured to perform the G.992.3, ATM, VC-MUX 0/38 <---> Ethernet frames conversion.
As my service is provided by TalkTalk, it is irrelevant as what the service login credentials are set. Although I have a classic email@example.com
plus alphanumeric string
allocated as the credentials, I routinely enter burakkucat
into the login & password fields . . . as the authentication is performed by the circuit ID.
So not knowing what the un-provisioned HHG2500 has set as the login & password should not be a problem. I would expect that if the EWAN port of the HHG2500 is active, then by connecting the LAN port of the MT882 to the EWAN port of the HHG2500 with a standard Ethernet patch cable I should be able to gain Internet access from the LAN ports of the HHG2500.
Does that read as a suitable experiment?
Or is there something else that I could try which would answer the question that you have posed?
