Assuming you have a single line, then the blue/white pair would be used. You just have to connect that to the jack on the modem. It doesn't matter where you find that pair to connect to it. While you're at it, you might want to get rid of that "biscuit". Either get a proper 3 way splitter, if still needed, or use that 110 strip to break out to multiple phones.Thanks for any input you can give.
BTW, 110 strips are unusual in Canada. I've only seen one. Telcos generally install a BIX strip. Did Rogers provide it? I've only seen them use BIX. With BIX, it's easy to set up parallel connections, as the punch can be configured to punch only, but not cut. I've never tried that with 110.
The 110 is common in the U.S., but I was surprised to see a bunch of BIX in the State Farm headquarters, in Indianapolis, Illinois, when I was down there several years ago.
