  For a sequence of complex numbers $\Lambda$ we consider the restriction
operator $R_{\Lambda}$ defined on Paley-Wiener spaces $PW_{\tau}^{p}$
($1<p<\infty$). Lyubarskii and Seip gave necessary and sufficient conditions on
$\Lambda$ for $R_{\Lambda}$ to be an isomorphism between $PW_{\tau}^{p}$ and a
certain weighted $l^{p}$ space. The Carleson condition appears to be necessary.
We extend their result to $N-$Carleson sequences (finite unions of $N$ disjoint
Carleson sequences). More precisely, we give necessary and sufficient
conditions for $R_{\Lambda}$ to be an isomorphism between $PW_{\tau}^{p}$ and
an appropriate sequence space involving divided differences.
