47 CFR § 42.11 - Retention of information concerning detariffed interexchange services.
(a) A nondominant IXC shall maintain, for submission to the Commission and to state regulatory commissions upon request, price and service information regarding all of the carrier's international and interstate, domestic, interexchange service offerings. A commercial mobile radio service (CMRS) provider shall maintain such price and service information only about its international common carrier service offerings and only for those routes on which the CMRS provider is classified as dominant under § 63.10 of this Chapter due to an affiliation with a foreign carrier that collects settlement payments from U.S. carriers for terminating U.S. international switched traffic at the foreign end of the route. Such a CMRS provider is not required to maintain its price and service information, however, on any such affiliated route if it provides service on that route solely through the resale of an unaffiliated facilities-based provider's international switched services. The price and service information maintained for purposes of this paragraph shall include documents supporting the rates, terms, and conditions of the carrier's international and interstate, domestic, interexchange offerings. The information maintained pursuant to this section shall be maintained in a manner that allows the carrier to produce such records within ten business days. For purposes of this paragraph, affiliated and foreign carrier are defined in § 63.09 of this chapter.
(b) The price and service information maintained pursuant to this section shall be retained for a period of at least two years and six months following the date the carrier ceases to provide services pursuant to such rates, terms and conditions.
