65- 407 C.M.R. ch. 280, § 7
All interexchange carriers shall pay access charges as required by section 8 of this Chapter, and their continued authorization to provide service is contingent upon such payment. Where it is technically possible to distinguish and separate intrastate from interstate traffic, LECs shall deny intrastate access to interexchange carriers (IXCS) that are telephone utilities as defined in 35-A M.R.S.A. §102(19) but are not authorized to provide intrastate telecommunications services. Where the LEC or LECs cannot deny access and the unauthorized IXC can block unauthorized traffic, the IXC shall block all such intrastate traffic. For unauthorized intrastate interexchange traffic that cannot be blocked, the unauthorized IXC shall pay a charge that is equal to the undiscounted Message Telecommunications Service (MTS) of the local exchange carrier.
