Figure 61 - Layer, protocols, and interfaces applicable to Dataradio implementation
All statistics presented by CalAmp follow a convention presented in Figure 62. Layer n statistics are giv-
en with respect to the layer immediately below it: layer n-1. RX (Receive) or IN refers to data received by
layer n from layer n-1. Transmit (TX) or OUT refers to data transmitted by layer n to layer n-1.
