QXDM Capture Tool

QUALCOMM eXtensible Diagnostic Monitor (QXDM) is a debug tool designed by Qualcomm, which allows you to trace and debug the data through mobile trunks.

Prerequisites

Make sure a GSM/3G/4G LTE module is installed in the correct slot:

  • S412: Slot3
  • S20: Slot1
  • S50: Slot1
  • S100: Slot1 on Expand Board1
  • S300: Slot1 on Expand Board1

Procedure

  1. Log in to the PBX web interface, go to Maintenance > Troubleshooting, click QXDM Capture Tool.
  2. Click Start.

    The PBX starts to trace data through mobile trunk. During this time, you should duplicate the problem of the GSM/3G/4G LTE trunk.

  3. Click Stop to stop tracing data.
  4. Click Download to download the captured packet.
    Tip: Decompress the .tar file and use Wireshark software to open the packet file.
