Not mine. Good luck accessing to the modem you provided which I reconfigured to be a dumb bridge and terminated the ADSL connection on my router. Oh, the router neither see the POTS line (it only gets Ethernet) nor have remove management capabilities.

Where endpoints are heterogeneous, there's guaranteed, real fun (Even more so if you make assumptions).

And this is why providers hate heterogeneous networks :-) Mine politely asks you to plug in the original modem before they'll help you debug a connectivity issue. But even then, there are sometimes standards like TR-069 that apply across vendors.
