NME–3 PAMS Technical Documentation JBD–2 User Guide Introduction JBD–2 is used to test the NME–3 in the Service Center. It is possible to use the JBD–2 for testing, analyzing, repairing, and fault logging of the Radio Unit (RU) and the Handset (HS). JBD–2 is an interface between the phone and the computer when WinTesla service software is running. With the JBD–2, it is possible to simulate a normal call, to check all interfaces are working and to run a final test via WinTesla service software.
NME–3 PAMS Technical Documentation JBD–2 User Guide Common Functional Description In the Test Interface Box (JBD–2), the different audio signal paths are switched with relays. The actual setting is displayed with LED’s. In addition the original handsfree equipment can be connected. Two VDA–signals (IGNS and BLD) will be set from the JBD–2. The AMC and CRM signals are tested from the JBD–2. The RS–232 from NME–3 can be tested by using WinTesla together with RS232 test circuit of the Test Interface Box.
NME–3 PAMS JBD–2 User Guide Technical Documentation Figure 2. Rear Panel Map Modes of Operation JBD–2 has three operation modes. They are selectable with the switch 1 (TEST/FLASH/FLS1). The general mode is TEST. In this case, the box is testing all interfaces from NME–3.
NME–3 PAMS Technical Documentation JBD–2 User Guide Possible Audio Test Paths There are six different audio modes. All audio modes are selectable with the switch . Set the switch into the upper position then change the JBD–2 into the next mode. Switching to the next mode will be indicated by a shift of the indicator LED one position to right. On the end of the LED line, there is a wrap around with the next push up.

NME–3 PAMS JBD–2 User Guide Technical Documentation Test Setup HS PC TDC–4 JBD–2 AOUT OSCI CH1 CH2 RU AIN Signal Generator Measure Application The ear path can be tested by injecting a sinusoidal signal to AIN then a tone can be detected on the HS. To test the microphone path, inject a tone in the microphone of HS and measure the signal with oscilloscope at AOUT. In addition, with an acoustic coupler between ear and microphone in HS you can estimate the audio HS path with an oscilloscope.

While the RU is running press the IGNS switch (operates/stroke) for a short time in the other position, WinTesla will show the changes in a window. BLD The signal can be superimposed (supercharged) with fixed values of a PWM. If the backlight signal is active the green LED (BLD), has to be lit.
NME–3 PAMS JBD–2 User Guide Technical Documentation Test Setup HS PC TDC–4 JBD–2 RU Measure Application With the tappet switch it is possible to inject a specific PWM signal. E.g., 75% and WinTesla reads the converted signal from NME–3–RU and show it in the correct window. Check if the signal value meets the expected value. RS232 Test Connect to the RS232 interface to test the functionality of the connector.
NME–3 PAMS Technical Documentation JBD–2 User Guide • In the advance–loop mode check the RI and DCD lines. The service SW has to ensure care that the lines CTS & DSR are activate during measurement. Test Setup HS PC TDC–4 JBD–2 RU RS232 Measure Application Activate the loop–back test in WinTesla. The test result will be displayed in a window of WinTesla. Additionally the RS232 control lines can be tested discretely. This is using the settings in WinTesla.
NME–3 PAMS JBD–2 User Guide Technical Documentation Operation Mode FLS1 In this mode, the NME–3–RU can be reprogrammed with the new flash concept. HS MBUS FLS–1 JBD–2 PC RU Figure 15. Principle new Flash concept Power Distribution Diagram The main operational voltage is +5 and +12V, but the balanced–to–unbalanced and unbalanced–to–balanced converters need a special operating voltage: +10V. In the audio mode 5, the power supply of the handset will be supplied from the JBD–2.
