|Not to pick knits guys but........most every home in north america has a single phone line coming into the house yes, but, it's a 2 pair (ie: 4 wire) line and each phone connection itself uses only 2 wires. So, you have enough for two separate phone's (or two separate DSL connections) in your home. |
But, as jefro pointed out, if you had two separate DSL connections, you'd be paying for them and you'd know it.
When they first came out with DSL where I live, they used to put a filter on the line with the DSL connection. These days, they give you little filters you actually plug into the wall jacks and then you connect your telephone to the filter. With my most recent connection, I got 4 filters. These are required on the lines with the telephone(s) attached.
'cooleydd' may be talking about a situation where they've put a filter on the line for the actual DSL connection. This wouldn't make for two separate DSL connections but would give you two separate places you could plug your DSL modem into.
coolyedd: you can find out simply by plugging your DSL modem into the second location. Does it work? If yes, then you can use it, if no, then it's not a DSL connection and you can't. But I would bet it's not a "second separate" connection. As again, you would know if it were because you'd be paying for it.
You could always call your provider and talk to them about it and find out for sure.
