We present a large family of -valued discrete spectral problems.
The associated discrete nets generated by the so called Sym--Tafel
formula are circular nets (i.e., all elementary quadrilaterals are
inscribed into circles).
These nets are discrete analogues of smooth multidimensional
including isothermic surfaces, Guichard nets, and some other families
of orthogonal nets.
