Check out this link
http://www.dslreports.com/forum/rema...9180~mode=flat for another Siecor-Corning POTs splitter, and this link
http://www.dslreports.com/forum/rema...2760~mode=flat for installation. I bought one of the Seicor-Corning (my telco and aDSL service is SBC-Ameritech (SBC/Yahoo).
Took only about five minutes to install the splitter (once I read the instructions

) and wire the POT line to the splitter and re-wire my old (long inactive) unbunlded loop line as my new "homerun."
PS: I bought my splitter from "KAIFS" mentioned in these two threads. Ordered and paid by Paypal Friday about 6pm, he shipped before noon Saturday, I rec'd the unit Tuesday and was up and running by 4:30pm. Splitter+homerun has made significant difference in stability and speed.
