Hi,
I am implementing CRC-4 checksum on E1 transmitted data.
--------------------------------------------------------------------------------------------
CRC-4 is structured in a multiframe consisting of 16 frames numbered 0 to 15.The CRC-4 multiframe is then divided into two eight frame Sub-Multiframes (SMF) called SMF I and SMF II. Each SMF contains four CRC-4 bits designated C1, C2, C3, and C4.the CRC-4 bits sent in each SMF are compared to each other and if they match, the frame is considered error free. Bit 1 is used for the CRC-4 bits.
--------------------------------------------------------------------------------------------
So My point is during comparison of SMF its means in the same multiframe CRC-4 bit of SMF1 must be equal to CRC-4 bit of SMFII.Please provide me help on how we can compare CRC-4bit of SMF.
Regards,
