  High resolution optical spectra (R = 60 000) of the LBV star P Cyg beyond
outburst were obtained on the 6-meter BTA telescope in the wavelength range
477-780 nm. We perform a detailed identification of different types lines
(photospheric absorptions, permitted and forbidden emissions, components of
lines with P Cyg type profiles), and studied the variability of their profiles
and radial velocities. The average radial velocity from positions of forbidden
emissions ([NII] 5754.64, [FeII] 5261.62, [FeII] 7155.14 and [NiII] 7377.83
\r{A}) is accepted as the system velocity Vsys=$-34\pm1.4$ km/s. About a dozen
photospheric absorptions of CNO triad ions and SiIII are found, their stable
position, Vr(abs)=$-73.8$ km/s, shifted relative to at $-40$ km/s, indicates
that these absorbtions are formed in the pseudophotosphere region. The
high-excitation emissions ([OI] 5577, 6300, 6363 \r{A}, [OIII] 4959 and 5007
\r{A}, as well as HeII 4686 \r{A}) are absent in the spectra. The radial
velocity Vr(DIBs)=$-11.8$ km/s according to the position of numerous DIBs is
consistent with the position of the interstellar components of the D-lines NaI
and KI forming in the galactic Perseus arm. A color excess E(B-V)=0.34+/-0.03
mag and interstellar absorption Av=1.09 mag were determined by measurements of
equivalent widths of nine DIBs.
