(2) Transmission Message
One transmission message consists of 128 bytes of data. Each byte represents by ASCII codes the data to
be transmitted (Refer to Table below). The contents of the data to be transmitted vary with the kind of call,
but the first byte is always transmitted by ASCII code K (4B hex.). The second byte to be transmitted is the
data which specifies the kind of call.
If FCCS service is involved, the message can consist of more than 128 byte data.
