Traditional alternating tone signal for wire identification, audible resistance/capacitance level measurement. Audible line condition testing (level) indicates dead, working and off-hook lines. Line 1 and 2 polarity testing using 4-conductor modular plug. Improved talk battery supply for communication over inactive pairs. Tone and test functions using either modular plug or 24" alligator clip leads. Audible resistance level measurement. Audible capacitance level measurement. Battery operated (9V)
