SIM CAR
RH-48 supports SIM CAR. The following waveform may be used to verify that sim_vcc; 
sim_i/o, cim_clk, and sim_rst signals are activated in the correct sequence at power up. 
This picture may be taken when the SIM CAR is installed on the phone to measure the 
signals when the phone is turned on. The diagram shows the proper waveforms when the 
interface is working. See Figure 23 (bottom view) diagram for the test point’s location.
