Click this button to view your DSL connection's Asynchronous Transfer Mode (ATM)
statistics. ATM is a networking technology that provides high-speed data transfer.
ATM uses fixed-size packets of information called cells. With ATM, a high QoS
(Quality of Service) can be guaranteed.
The SAR driver is
These counters are set back to zero whenever the device
inPkts is the number of good ATM cells that have been received.
inDiscards is the number of received ATM cells that were rejected.
outPkts is the number of ATM cells that have been sent.
outDiscards is the number of ATM cells sent that were rejected.
inF4Pkts is the number of ATM Operations, Administration, and Management
(OAM) F4 cells that have been received. See ITU recommendation I.610 for more on
OAM for ATM.
outF4Pkts is the number of ATM OAM F4 cells that have been sent.
inF5Pkts is the number of ATM OAM F5 cells that have been received.
outF5Pkts is the number of ATM OAM F5 cells that have been sent.
openChan is the number of times that the ZyXEL Device has opened a logical DSL
channel.
closeChan is the number of times that the ZyXEL Device has closed a logical DSL
channel.
txRate is the number of bytes transmitted per second.
rxRate is the number of bytes received per second.
Click this button to start the ATM loopback test. Make sure you have configured at
least one PVC with proper VPIs/VCIs before you begin this test. The ZyXEL Device
sends an OAM F5 packet to the DSLAM/ATM switch and then returns it (loops it
back) to the ZyXEL Device. The ATM loopback test is useful for troubleshooting
problems with the DSLAM and ATM network.
