Diagnostic
This window is used for hardware testing of the Creative DSL PCI 7430 card.
ADSL Statistic
This window keeps tabs on errors that might affect the overall system performance. The counts
are reset whenever the PC system is restarted. This window contains three sub-categories:
a. ADSL Information
Re-training Count
This tracks the number of ADSL connections performed. Due to unexpected line condition
changes, the drivers can retrain the connection causing the ‘Re-training Count’ total to
increment. The ‘Diagnostic Tool’ icon will flash yellow while reconnecting.
FEC Count
This tracks the forward error correction count.
CRC Count
This tracks the accuracy of correcting data errors over each 17msec.
ATM HEC Count (header error check)
This records errors as an indication of ATM packet accuracy.
b. ATM Received Side Statistics
Good Received Packets
Bad Received Packets
c. ATM Transmission Side Statistics
Transmitted Packets
ADSL implements Reed Solomon (RS) error checking:
As a measure of packet transfer performance, the ‘Packet Errors’ are counted and tracked
against the total number of ‘Packets Received’. An error rate of less than 0.1% is reasonably
under clean ADSL line conditions.
If you have Bad Received Packets and are concerned about your service, multiply the ‘Bad
Received Packets’ count by 1000 and compare the result with the total ‘Packets Received’
count. If the number is smaller than the total ‘Packets Received’ count, then the board is operating
normally.
