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

The format of the random access message at the data link layer consists of 8 bits. The order of bit transmission is defined in 3GPP TS 44.004.

Annex G (normative):
Handling of frames with parameter errors in the address, control and length indicator fields
