ACR TimeStamp Setup
Adaptive Clock Recovery (ACR) is a process that negates the effect of random packet
delay variation and captures the average rate of transmission of the original bit stream.
ACR recovers the original clock for a synchronous data stream from the actual payload of
the data stream. ACR is a technique where the clock from the TDM domain is mapped
through the packet domain, but is most commonly used for Circuit Emulation (CEM).
This function is mainly used for RD analysis. When the equipment has encountered
malfunctioned and the cause cannot be found at the same time, using ACR TimeStamp
to search for the data at each time stamp that has already been analyzed by the RD. This
function is not required for normal use.
