I want to reiterate what Arthur said about toners and probes. With everybody getting into the act these days there is a lot of junk out there and the proper equipment will either make your job easy or impossible. I have always used exactly what Arthur uses and if you aren't an old telecom guy you probably have no idea who Aines is. Notice the metal tip on the probe? I second one of the methods of sticking the probe into the end of each cable but if you try that with a probe with an insulated tip it ain't gonna work (assuming that the probe itself has sufficient amplification).
