Hello everyone. I am a woman technician who has been learning on the job and love this line of work--even the cabling! I found tek-tips over a week ago and have learned so much from all of you guys here--it's a great site. Ok, I have a customer who has bad static only on their line one, not any of the other 3 c.o.s going through the ksu. This has been ongoing for almost a year now, but because it is an intermittent static, hard to diagnose. Sprint has come out and checked 2 times now and says it is not on their end. I pulled the cross connect wire off and listened directly to the line with the buttset and heard some static--can I test Sprint's line somehow myself, as obviously it's not happening while they are there. One more question, IF it could be the KSU (just for future reference), how would you test that port? Thank you for any help you can throw my way--
