There is probably a simple solution to this. My cable modem is directly below my office and I have already run my network cables to a keystone plate with no problem. I now want to run a telephone cable from the modem to the last insert of the keystone using this http://www.homedepot.com/p/CE-TECH-V...H-10/204410599 I had an older flat 4 wire cord laying around so I connected it as follows red wire to 3, green to 4, black to 2, and yellow to 5 but no signal. Should I be using a better quality phone cable? Perhaps the cheaper cable is not making contact with the terminals? What am I missing to get a phone line to the keystone insert? Thanks in advance!
