PURPOSE: This rule describes the LEC-to-LEC network and adopts restrictions for use of that network.

1. (1) The LEC-to-LEC network is that part of the telecommunications network designed and used by telecommunications companies for the purposes of originating, terminating, and transiting local, intrastate/intraLATA, interstate/intraLATA, and wireless telecommunications services that originate via the use of feature group C protocol, as defined in 4 CSR 240-29.020(13) of this chapter. InterLATA wireline telecommunications traffic shall not be transmitted over the LEC-to-LEC network, but must originate and terminate with the use of an interexchange carrier point of presence, as defined in 4 CSR 240-29.020 (31) of this chapter. Nothing in this section shall preclude a tandem carrier from routing interLATA wireline traffic to a nonaffiliated terminating carrier over the LEC-to-LEC network, provided such terminating carrier has agreed to accept such traffic from the tandem carrier and such acceptance is contained in a commission-approved interconnection agreement.
