My current configuration has what appears to be an RJ11 connection going from the wall jack directly to my DSL modem.
Here is a picture of the faceplate; the blue jack is the phone line and the green jack is the "data" line.
However, this connection is in a central hallway and I'd like to move the modem to another room without having to rewire anything.
The disused blue RJ11 connection on the same faceplate is wired to other rooms, and I don't think its connected to anything externally. I believe this blue jack is intended to be the "line-in" connection with the modem translating VoIP calls over the DSL connection into an analog connection for telephones in other rooms.
I am not currently using this phone line, nor do I intend to use it for connecting a landline telephone or fax in the future.
Therefore, can I simply jumper from the current green "data" jack to the disused blue "phone" jack, and then connect the modem to a phone jack in a different room?
Is there any reason why I shouldn't attempt this?
And, if this is even viable, is there anything I should test or verify beforehand to ensure I won't risk damaging anything (e.g. checking for line voltage)?
Here is a picture showing the back of the faceplate with both jacks connected, albeit with what appears to be different wires within a shared cable:
I'm not sure whether there's a DSL splitter/filter present within the NID (Network Interface Device) box - I wouldn't know what to look for. Although here is a picture showing what's inside:
