"Network connection" − A voice grade communication channel directly between a subscriber and a telecommunications carrier's public switched network, without the intervention of any other telecommunications car­rier's switched network, that would be required to carry the subscriber's inter-premises traffic. The connection either is capable of providing access through the public switched network to a 9-1-1 system, if one exists; or if no system exists at the time a surcharge is imposed under Section 15.3 of ETSA, would be capable of providing access through the public switched network to the local 9-1-1 system if one existed.
