1. A method for determining at a central office site, whether or not a remote span-powered telecommunication unit is properly grounded comprising the steps of:

  • (a) providing, at said remote span-powered telecommunication unit, a controlled conduction path that is operative to selectively couple circuitry of said remote span-powered telecommunication unit to earth ground;

    (b) from said central office site, selectively applying said controlled conduction path and monitoring said span for the occurrence of a ground fault;

    (c) in response to detecting a ground fault as a result of application of said controlled conduction path, generating an output indicating that said remote span-powered telecommunication unit is properly grounded.
