    Except as provided in Sec. 22.901(d), equipment used in the Cellular 
Radiotelephone Service must be designed in compliance with the technical 
specifications for compatibility of mobile and base stations in the 
Cellular Radiotelephone Service contained in ``Cellular System Mobile 
Station-Land Station Compatibility Specification'' (April 1981 Ed.), 
Office of Engineering and Technology Bulletin No. 53. This bulletin is

Radiotelephone Service as specified in OET Bulletin No. 53 is not
