Response
Engineering Mode is designed to allow a field engineer to view and test the
network information received by a handset, when the handset is either in
idle mode or dedicated mode (that is: with a call active). In each mode, the
engineer is able to view network interaction for the "serving cell" (the cell
the handset is currently registered with) or for the neighboring cells.
TA returns the current engineering mode. The network information
including serving cell and neighboring cells are returned. <cell> carry with
them corresponding network interaction.
