  • MHz narrowband interoperability channels. The NCC recommends that the Commission amend this section to reflect a ``changed standard in the ANSI/TIA/EIA documents applicable to the narrowband voice/data channels.'' Specifically, the NCC states that the standard for automatic frequency control currently referenced in Section 90.548 of the Commission's rules (ANSI/TIA/EIA-102.BAAA-1998) will not meet the frequency stability requirements set out in Section 90.539 of the Commission's rules. The NCC recommends that the rules reference a revised document ANSI/TIA/EIA-102.BAAA-A-203 which now specifies a frequency stability that meets the rules. In addition, TIA-PRS notes that they have revised or reaffirmed several additional documents referenced in Section 90.548 and that these references should also be updated. Specifically, TIA-PRS suggests that Section 90.548 reference the following updated
