rates.
ATM / ADSL Statistics Menu
From this menu, the user will be able to see Error Count Information, ATM Transmission
statistics and ATM Receive statistics.
Error Count Information
Re_HSK Count - The number of times handshaking has occurred.
CRC error count - The number of cyclic redundancy check (CRC) errors accumulated
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.
