40、TIA/EIA-732-830PART 830 State Transition Tables for Mobile Data Link Protocol (MDLP)1 IntroductionThe MDLP state transition tables are two dimensional matrices that define all possible states (as columns) and events (as rows) that can occur within MDLP. Each element of the matrix enumerates the acti
41、on(s) to be taken when the specified event occurs in a particular state. A state transition table has been defined for the Data Link Layer Entity (DLLE), the Sleep Management Entity (SME), and the TEI Management Entity (TME).Since MDLP is an asymmetric protocol, the behavior and procedures for user
42、side CDPD devices differ from those used by network side CDPD devices. Thus, there are two sets of state transition tables defined: one set for the network side procedures and one set for the user side procedures.2 Reading the State Transition TableThe following legend explains how to interpret the
43、various symbols used in the MDLP state transition tables.2.1 ComparisonsAll sequence number comparisons in the state transition table are modulo. Consequently, some conditions may intuitively appear to be nonsensical but are valid.TIA/EIA-732-830 State Transition Tables for Mobile Data Link Protocol

46、s it is stopped. The state transition table does not distinguish between starting an inactive or restarting a currently active timer.Stop Timer The specified timer is stopped and the value of the timer at the time it is reset is of no significance. Stopping or resetting a timer has the same effect.2
