A power connector is connectable with a cable having a number of conductors and matable with a complementary connector for power transmission. The ONU separates the optical signal transmitted from the OLT into the broadcast signal and the communication signal, processes upstream information transmitted from a user, and optically transmits the broadcast signal and the communication signal selected on a user-by-user basis, on the basis of a time slot. The clamping member includes a first clamping post, a second clamping post, and a screw post located between the first clamping post and the second clamping post. The movable connector may alternately communicatively couple the first device with the second device via the first or second branch and disconnect the second or first branch respectively in response to corresponding placement of the second device in the first or second position. This invention relates to the maize variety X08D399, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of maize variety X08D399. The compounds and compositions of the invention can induce the biosynthesis of various cytokines and are useful in the treatment of a variety of conditions including viral diseases and neoplastic diseases.
