§9.10. 911 Service. — Inbound Citations

(8) If E911 obligations apply to the licensee (see § 9.10 of this chapter), the licensee retains the obligations with respect to leased spectrum. However, if the spectrum lessee is a Contraband Interdiction System (CIS) provider, as defined in § 1.9003, then the CIS provider is responsible for compliance with § 9.10(r) regarding E911 transmission obligations.

(8) To the extent the licensee is required to meet E911 obligations (see § 9.10 of this chapter), the spectrum lessee is required to meet those obligations with respect to the spectrum leased under the spectrum leasing arrangement insofar as the spectrum lessee's operations are encompassed within the E911 obligations. If the spectrum lessee is a Contraband Interdiction System (CIS) provider, as defined in § 1.9003, then the CIS provider is responsible for compliance with § 9.10(r) regarding E911 transmission obligations.

(4) If E911 obligations apply to the licensee (see § 9.10 of this chapter), the licensee retains the obligations with respect to leased spectrum. A spectrum lessee entering into a short-term de facto transfer leasing arrangement is not separately required to comply with any such obligations in relation to the leased spectrum. However, if the spectrum lessee is a Contraband Interdiction System (CIS) provider, as defined in § 1.9003, then the CIS provider is responsible for compliance with § 9.10(r) regarding E911 transmission obligations.
