Valid RTP Commands
The following list shows valid commands (CMDs):
The most significant bit of an RTP request block’s toggle+CMD byte is the toggle
bit. A new command is identified when the value of this bit changes and matches the
value of the toggle bit in the toggle+length byte.
A new RTP request is processed only if the preceding RTP request has finished.
Overlapping RTP requests are not allowed. A new RTP request made before the
completion of a preceding request is ignored.
To determine when an RTP command has been processed and its response is
complete, check the values of the toggle+CMD echo bytes in the RTP response
block. Continue to check both toggle+CMD bytes in the RTP response block until
they match the RTP request block’s toggle+CMD byte. Once they match, the
contents of the RTP response block is valid.
