DESCRIPTION
Click this 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.
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.
inF5Pkts is the number of ATM OAM F5 cells that have been received.
outPkts is the number of ATM cells that have been sent.
outDiscards is the number of ATM cells sent that were rejected.
outF4Pkts is the number of ATM OAM F4 cells that have been sent.
outF5Pkts is the number of ATM OAM F5 cells that have been sent.
Click this 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 AMG1302/AMG1202-TSeries sends
an OAM F5 packet to the DSLAM/ATM switch and then returns it (loops it back) to the
AMG1302/AMG1202-TSeries. The ATM loopback test is useful for troubleshooting
problems with the DSLAM and ATM network.
