Dear shola,

If you are talking about existing cable, the best way is with a piece of equipment that includes or is dedicated to a TDR function (Time Domain Reflectometor). Most tester that test for the various category type cable include this as part of their functionality.

Sincerely,
Joseph Golan, RCDD
