I had to split a 2 line Pots in order to add DSL service. I used a Radio shack L1,L2, L1+L2 splitter where L1 went to DSL modem and L1+L2 went to my PBX . The problem is that now when I use the L1 or L2 lines on my phones I can hear the other line in tthe background.
Is there a better way of splitting these lines? Any help appreciated.
