Explain Echoplex

It is a method used to detect error in data link layer and is also called echo checking.
Here reciever retransmits the data back to the transmitter after reception.

When data is received at the transmitter,error can be detected by the human operator .
Its disadvantage is that it depends on humans for error detection and correction.
