274 NPA delayed for two years [telecom]

What number conservation measures does Wisconsin mandate?

I'm not really sure, but I would assume them to be the fairly standard ones, such as carrier-to-carrier number portability, 1000 number block assignments, etc.

NXX assignments in 920 have been fairly slow over the past couple of years anyways (conservation measures, wireless market saturation plus the blah economy all to credit/blame?). Ditto in Wisconsin's 715, now 'officially' overlaid by 534, but still without a 534 NXX in revenue service after about four months of mandatory 10D local dialing and a significant number of remaining 715 NXXs still unassigned.
