   A measure of the electrical balance between the two conductors (tip and ring) of a telephone circuit; specifically, the difference between the tip-to-ground and ring- to-ground AC signal voltages, expressed in decibels. If the longitudinal balance of a circuit is insufficient, cross talk, electronic chatter, and miscellaneous noises can occur.
