I am running cable for a new wired desktop. I was going to go from the existing telus device and add a switch where one one the current devices are. There are four existing ports all in use. Teo lines run to some weird little junction that appears to wire directly to two of the lines in the house. The other two do the same for two other lines. It looks like telus cut the ends off my lines and wired them into these little boxes. Any suggestions. I can't see any way to add a switch to get more ports.
