The DR system returns the data sent by the MUX unchanged. The MUX
compares the returned data to the data sent in the circuit test request; if the data
matches, the circuit is established. If the data does not match, the circuit test
request is repeated. The DR system waits up to 5 seconds from receiving the
00 command (i.e., receiving EOT ) before transmitting ENQ for the 80
command.
