Reading pushed COSEM Object from tcp server (data frames)

Hi.
i can connect to meter with GXDLMSDirector via serial port.
i then push some register to a specific IP (that our server IP) and i can read its pushed values

it has some byte probably showing status header, clock, register, ... and every thing i selected to push and many 0 afterward
its 127 byte (my configured packet was of size 127)

but i cant decode these bytes, i don't know what they mean each.

i get these values from TCP server i made for testing

i realized (after pushing some different registers and clock) that there is clock byte in status and i can see the clock bytes what i wanted a document on how can i decode if i change the pushed value and what they mean or how many bytes do each value used

i cant push values if their size is big (like all COSEM objects), if i pushed for example 8 registers i cant but if i push like 7 in will do it and i will get some bytes followed by some 0.

is there any document on what are these bytes and how can i decode them?
i searched jDLMS library but i couldn't find decoding part.

can you tell me how can i decode them and what they means individual

thanks in advance
(sorry for poor english)
