Asynchronous Balanced Mode (ABM) is a communication mode of HDLC and derivative protocols, supporting peer-oriented point-to-point communications between two nodes, where either node can initiate transmission.
For systems that work in the ABM (Asynchronous Balanced Mode), there is no master/slave relationship. Each station may initialize, supervise, recover from errors, and send frames at any time. The DTE (Data Terminal Equipment) and DCE (Data Circuit Terminating Equipment) are treated as equals. The initiator for Asynchronous Balanced Mode sends an SABM
Famous quotes containing the words balanced and/or mode:
“I balanced all, brought all to mind,
The years to come seemed waste of breath,
A waste of breath the years behind
In balance with this life, this death.”
—William Butler Yeats (1865–1939)
“I have no scheme about it,—no designs on men at all; and, if I had, my mode would be to tempt them with the fruit, and not with the manure. To what end do I lead a simple life at all, pray? That I may teach others to simplify their lives?—and so all our lives be simplified merely, like an algebraic formula? Or not, rather, that I may make use of the ground I have cleared, to live more worthily and profitably?”
—Henry David Thoreau (1817–1862)
