said by Lorob:The tech also noted that I had the matching pairs at the distribution block all punched down, and advised that I clip all those that are not being used. He believes there is some inefficiency and performance hit when you distribute the DSL line to jacks throughout the house, even though only one jack is active.
Most likely causes an internal bridge tap. I received no SBC tech advice for a similar arrangement that I created, but my signals definitely changed for the worse, once I rewired as a star. I just clipped the unused pairs at the panel, and my connection went back to the levels I had before re-wiring. Figured it out on my own.
