Abstract
A system and method is provided for facilitating robust reception of multiple frame protocol messages. Initially, a first frame of data is received including therein a first segment of a multi-frame protocol message. Next, the received frame is placed into a data buffer. The buffer is then examined and the message contained therein is parsed to determine whether the received message is a complete message or not. If it is determined that the received message contained in the buffer is an incomplete message, a continuation message is sent to the remote transceiver ATU. However, if the message is determined to be complete, the message is parsed again and the complete message information contained therein is extracted and processed in accordance with the handshaking requirements. Upon receipt of the next frame in the message, this frame is concatenated onto the existing frames in the data buffer. The entire buffer is then re-parsed to determine its completeness. If incomplete, the process repeats until a completed message is identified.
