The LPT take place between the Transmission sink and source, while the LLF is between Client to Client:

Hi Lylanadya, the CCM is Continuous Check Messager. It acts like a ping to the devise continuously, but in a message.

Hi Steve, good question. When we implemented both LPT and LLF, the result is just like we implement the LLF only.
