  We construct holomorphic local conformal framed nets extended from a tensor
power of the Virasoro net with c=1/2 with a pair of binary codes (C,D)
satisfying the conditions given by Lam and Yamauchi for holomorphic framed
vertex operator algebras. Our result is an operator algebraic counterpart of
theirs, but our proof is entirely different. We apply the alpha-induction in
order to identify the representation theory of "code local conformal net" and
this gives rise to the existence of the desired local conformal net.
