  Charge transport in tunnel junctions between singlet anisotropically paired
superconductors is investigated theoretically making use of the Eilenberger
equations for the quasiclassical Green functions. For specularly reflecting
tunnel barrier plane we have found and described analytically characteristic
singular points of the I-V curves which are specific for the case of
anisotropic pairing. All four terms for the electric current are examined. Two
of them describe ac Josephson effect and two correspond to the quasiparticle
current (the last term occurs only for a time-dependent voltage). Various
momentum dependences of the order parameter in the bulk of superconductors and
different crystal orientations are considered. The results of numerical
calculations for the total I-V curves are presented for some particular cases.
