Section 730.715 Service
Outside Exchange Boundaries
a) No telecommunications service will be established outside the
exchange boundary of the exchange that normally would provide service except on
an emergency temporary basis or after the serving local exchange carrier has
filed a notice of proposed boundary change with the Commission.
b) In cases where local exchange telecommunications service is
provided outside the exchange boundary of the normal serving exchange without
authorization of the Commission (other than foreign exchange service) and the
location of the service is in the exchange of another local exchange carrier
certificated by the Commission, the service shall be discontinued as soon as
facilities are made available from the exchange in which the service is
located. The customer whose service is affected by this Section shall be given
at least 90 days notice prior to the time service can be provided from the
proper telephone exchange.
