Hi,
I have some queries regarding the GSM.
What are the Layer1 and layer 2 functions?
How a data packet filters?
How the systems recognize whether the data packet is of data or control
signal?
What are the role of DLP at layer2?
What are the role of Length identifier and Fill bits?
Difference between A, B Abis and Bbis LAPDm frame format?
Regards,
Saurabh
