The invention discloses a multifunctional port traversal test board for a voice terminal device and relates to the field of voice testing in optical-fiber communication. The test board includes four test modules which are different in sequence number of input lines, but identical both in basic structure and function. Each test module includes a slideway, a sliding double-selection switch, odd/ even number input lines in 16 pairs of Tip and Ring input lines, a Tip output line, a Ring output line, two contact pins, three via holes, seven single-selection switches, five resistors and a capacitor. The multifunctional port traversal test board for the voice terminal device is capable of testing a plurality of functions of on-hook detection, off-hook detection, flash hook detection, pulse number detection, ringing, ring cutting, feed voltage, feed current, reverse billing, pulse billing, user loop resistance, gain adjustment, impedance interface method and voice Z interface testing and the like so that self-testing time of a laboratory can be shortened significantly and testing efficiency and accuracy can be improved. The multifunctional test board is convenient to store and produce in batch.
