Power Failure Transfer

In telecommunication, the term power failure transfer has the following meanings:

  1. The switching of primary utilities to their secondary backup whenever the primary source operates outside its design parameters. This is accomplished via a transfer switch.
  2. In telephony, a function which, when activated in the event of a commercial power failure or a low-voltage battery condition at a subscriber location, supplies power to predesignated subscriber equipment via the central office trunk.

Power-failure transfer is an emergency mode of operation in which one and only one instrument may be powered from each trunk line from the subscriber location to the central office.

Famous quotes containing the words power, failure and/or transfer:

    To play safe, I prefer to accept only one type of power: the power of art over trash, the triumph of magic over the brute.
    Vladimir Nabokov (1899–1977)

    Government is actually the worst failure of civilized man. There has never been a really good one, and even those that are most tolerable are arbitrary, cruel, grasping and unintelligent.
    —H.L. (Henry Lewis)

    If it had not been for storytelling, the black family would not have survived. It was the responsibility of the Uncle Remus types to transfer philosophies, attitudes, values, and advice, by way of storytelling using creatures in the woods as symbols.
    Jackie Torrence (b. 1944)
