Chapter 25 Diagnostic The following table describes the fields in this screen. Table 81 Maintenance > Diagnostic > DSL Line ITEM 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. ATM Loopback Test outDiscards is the number of ATM cells sent that were rejected. 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. P-661HNU-Fx User's Guide 263
