DESCRIPTION
ATM
Status
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 (Segmentation and Reassembly) SAR driver translates packets into ATM
cells. It also receives ATM cells and reassembles them into packets.
These counters are set back to zero whenever the device starts up.
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.
ATM
Loopback
Test
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.
