Bipolar violation; the detection of any isolated error, whether it deletes a pulse or adds a pulse

See Bipolar Violation.

A condition which occurs when an AMI-coded signal contains a pulse of the same polarity as the previous pulse and which is not part of a bipolar zero substitution code (e.g., B8ZS for a DS1 signal or B3ZS for a DS3 signal).

Benign Positional Vertigo. also called Benign Paroxysmal Positional Vertigo describes a vertigo which is often induced while a patient turns over in bed, or gets in and out of bed. It is a benign disorder, which while it will remit spontaneously, often reappears. It is diagnosed by the use of the Dix Halpike Maneuver. BPV is often cured, just after it is diagnosed, by a maneuver performed by the treating doctor, which dislodges a clot of material from one of the inner ear canals.
