Barker code

signals are equal in voltage to ground but opposite in polarity, which has the effect of reducing radiated energy and, therefore, reducing attenuation. See also unbalanced and UTP. 2. Referring to symmetrical relationship. For example, the X.25 protocol suite includes Link Access Procedure-Balanced (LAP-B), a balanced protocol that operates in Asynchronous Balanced Mode (ABM), which refers to the fact that the devices have a balanced, rather than a master/slave, relationship.Therefore, a device at either end of the link can initiate a dialogue at any time. See also ABM, LAP-B, master/slave, and X.25.
