Dying Gasp is a message (or signal) sent by the customer premises equipment (CPE) DSL device to the digital subscriber line access multiplexer (DSLAM) when a power outage occurs. A DSL interface with dying gasp must derive power for a brief period from another source so that the message can be sent without external power. The dying gasp message will end the session and a new session will be able to be made as soon as power returns and the modem retrains.
Dying Gasp is referenced in section 7.1.2.5.3 of ITU-T Recommendation G.991.2 (12/2003) as the Power Status bit.
Famous quotes containing the words dying and/or gasp:
“The night has a thousand eyes,
And the day but one;
Yet the light of the bright world dies
With the dying sun.”
—Francis William Bourdillon (18521921)
“Postmodernism is, almost by definition, a transitional cusp of social, cultural, economic and ideological history when modernisms high-minded principles and preoccupations have ceased to function, but before they have been replaced with a totally new system of values. It represents a moment of suspension before the batteries are recharged for the new millennium, an acknowledgment that preceding the future is a strange and hybrid interregnum that might be called the last gasp of the past.”
—Gilbert Adair, British author, critic. Sunday Times: Books (London, April 21, 1991)
