Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

The following table shows the trace record content for MME.

The trace record is the same for management based activation and for signalling based activation.

MME shall support at least one of the following trace depth levels – Maximum, Medium or Minimum.
