Section 196.217 - Average toll rates(1) DIFFERENT RATES RESTRICTED. A telecommunications utility may not charge different rates for residential basic message telecommunications service, business basic message telecommunications service, or single-line wide-area telecommunications service on routes of similar distances within this state, unless authorized by the commission. This subsection does not prohibit volume or term discounts, discounts in promotional offerings, differences in the rates for intralata and interlata services of similar distances, the provision of optional toll calling plans to selected exchanges or customers or the passing through of any state or local taxes in the specific geographic area from which the tax originates.(2) TOLL SERVICES. Notwithstanding sub. (1), a telecommunications utility may charge prices for toll services under contract that are unique to a particular customer or group of customers if differences in the cost of providing a service or a service element justify a different price for a particular customer or group of customers, or if market conditions require individual pricing.(3) AVERAGED RATES. Notwithstanding subs. (1) and (2), an intralata toll provider shall offer all optional toll calling plans on a statewide basis at geographically averaged rates until the provider deploys intralata dial-1 presubscription, except that an optional toll call plan need not be offered where deployment of that offering would not be economically or technically feasible.
