Purpose and Scope This standard specifies a Radio Link Protocol (RLP1) that layer-3 functions may use to asynchronously transport data octets across a TDMA radio interface. RLP1 requires an underlying half-rate@ full-rate@ double-rate@ or triple-rate digital traffic channel as specified in TIA-136-131@ 132@ and 133 [7]. To aid the reader@ ?? 2 and 3 contain descriptive information: ?? provides an overview; ?? describes the protocol's structure. ?? 4 and 5 contain requirements: ?? specifies RLP1 signals; ?? specifies processes. References appear in ??. Finally@ Annex A illustrates protocol operation@ and Annex B lists and defines acronyms. Note that ?? refers to figures too large to fit within the body of the standard. These figures are enclosed in a separate envelope. Readers will find the following documents helpful in understanding this standard: X.200 [4] and Z.100 [5]. Similar to X.200@ this standard uses reference models to organize concepts and requirements into a logical structure. These reference models are not meant to unnecessarily constrain implementations ?? any RLP1 implementation that@ as a whole@ behaves the same as the RLP1 specified in this standard@ by definition@ complies with this standard. If the requirements of this standard conflict with the requirements of referenced standards@ this standard shall govern.
