Each test generates one of the following result codes:
Statistics
When you click the Statistics link, the Links Bar expands to display seven statistical sub-
headings: DSL, ATM, Ethernet (supported models only), IP, LAN, Wireless (supported mod-
els only), and Logs. These screens will vary depending on your Gateway’s model and traffic
activity.
DSL
When you click DSL , the DSL Statistics page appears.
The DSL Statistics page displays information about the Router's WAN connection to the
Internet.
• Line State: May be Up (connected) or Down (disconnected).
• Modulation: Method of regulating the DSL signal. DMT (Discrete MultiTone) allows con-
nections to work better when certain radio transmitters are present.
• Data Path: Type of path used by the device's processor.
Downstream and Upstream statistics
• Max Allowed Speed (kbps): Your maximum speeds for downloading (receiving) and
uploading (sending) data on the DSL line, in kilobits per second.
• SN Margin (db): Signal to noise margin, in decibels. Reflects the amount of unwanted
“noise” on the DSL line.
• Line Attenuation: Amount of reduction in signal strength on the DSL line, in decibels.
• CRC Errors: Number of times data packets have had to be resent due to errors in
transmission or reception.
