4 Phased Implementation by Software Release
The AT commands described in this document have been implemented into various ISU models in a phased software
release approach, building on previous implementations. The Phase I AT Commands have been implemented in all ISU
models. The Phase II, III, IV, V, VI and VII AT Commands have been implemented in other ISU models as shown in
Table 4-1 below.
Note that some AT commands select operation that is dependent on Iridium network service capability.
