From this menu, the user will be able to see ADSL Information, ATM Transmission 
statistics, ATM Receive statistics and ADSL Connection Information. 
 
ADSL Information 
Re_training - The number of times handshaking has occurred. 
FEC Count - The number of forward error correction accumulated during showtime. 
 
CRC - The number of cyclic redundancy check (CRC) errors during showtime. The 
count will be reset to zero after the next handshaking. During showtime, the receiver 
keeps checking the CRC check sum for each received superframe. If there is a 
mismatch between the received check sum and the locally calculated check sum, a 
CRC error has occurred. 
 
ATM HEC - The number of ATM header error check (HEC) errors accumulated during 
showtime. The count will be reset to zero after the next handshaking. After entering 
showtime, the ATM TC layer at the reciever will undergo a cell delineation hunting 
process by finding the header of each received ATM cell. After successfully finding the 
cell delineation, the ATM TC layer will keeps checking the HEC check sum for each 
received ATM cell. If there is a mismatch between the received check sum and the 
locally calculated check sum, an ATM HEC error has occurred.
