EncodixOnline - Decoder: 3GPP2 C.S0005 (cdma2000)

The online version of the Encodix multistandard 5G/LTE/3GPP/WiMax/cdma2000 encode/decode C code generator (see the list of available decoders).

The C.S0005 decoder, based on the Encodix code generator, decodes the 3GPP2 SDUs as defined by specification C.S0005 for all revisions up to REV-13 (see 3GPP2, C.S0005-F 2.0).


We would like to decode a Data Burst Message (DBM) on the r-dsch using REV 7; this SDU is defined on C.S0005 at chapter

This is how it is defined on the specification:

We want to set MSG_NUMBER=12, BURST_TYPE=4, NUM_MSGS=4 and NUM_FIELDS=5; then the five CHARi fields will be set to 1, 2, 3, 4 and 5. Click here to run the decoder.

Binary input field

The binary input field supports the following format:

0/1Numbers 0 and 1 are inserted as bits. So 1100 is encoded as four bits 1, 1, 0 and 0.
dNwhere N is a decimal value in range 0..255; it is encoded as an 8 bit value. For example, d240 will be encoded as 11110000.
xNwhere N is an hex value in range 0..FF; it is encoded as an 8 bit value. For example, xF0 will be encoded as 11110000.
d{K}N / x{K}NSame as dN/xN but encoded in K bits. For example, d{3}2 will be encoded as 010.
