47 CFR 22.947 - Discontinuance of service.
(a)Termination of authorization.
(1) Except with respect to CMA672-A (see paragraph (a)(2) of this section), a licensee's Cellular Geographic Service Area (CGSA) authorization will automatically terminate, without specific Commission action, if the licensee permanently discontinues service. A new-system licensee is not subject to this provision until after expiration of the construction period specified in § 22.946.
(2) The licensee's authorization for CMA672-A (Chambers, TX) will automatically terminate, without specific Commission action, if the licensee permanently discontinues service after meeting its interim construction requirement as specified in § 22.961(b)(1).
(b)Permanent discontinuance. Permanent discontinuance of service is defined as 180 consecutive days during which a Cellular licensee does not operate or, in the case of a commercial mobile radio service provider, does not provide service to at least one subscriber that is not affiliated with, controlled by, or related to the providing carrier.
(c)Filing requirements. A licensee that permanently discontinues service as defined in this section must notify the Commission of the discontinuance within 10 days by filing, via the ULS, FCC Form 601 requesting license cancellation. An authorization will automatically terminate, without specific Commission action, if service is permanently discontinued as defined in this section, even if a licensee fails to file the required form requesting license cancellation.
