Ping test verifies the overall downstream/upstream communication route and connectivity of a DSAM within the Ethernet system. The ping test allows you to select the IP address, packet size, and time between pings and displays ping test result data that includes; round trip time, time-to-live (TTL), packets sent and lost, average round trip time, and loss to sent ratio. To perform the Ping test, press the VIEW softkey, use the arrow keys to select Ping, and press ENTER.
