In telecommunication, the term power failure transfer has the following meanings:
- 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.
- 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:
“You only have power over people so long as you don’t take everything away from them. But when you’ve robbed a man of everything he’s no longer in your power—he’s free again.”
—Alexander Solzhenitsyn (b. 1918)
“Girls tend to attribute their failures to factors such as lack of ability, while boys tend to attribute failure to specific factors, including teachers’ attitudes. Moreover, girls avoid situations in which failure is likely, whereas boys approach such situations as a challenge, indicating that failure differentially affects self-esteem.”
—Michael Lewis (late–20th-century)
“No sociologist ... should think himself too good, even in his old age, to make tens of thousands of quite trivial computations in his head and perhaps for months at a time. One cannot with impunity try to transfer this task entirely to mechanical assistants if one wishes to figure something, even though the final result is often small indeed.”
—Max Weber (1864–1920)
