LABEL DESCRIPTION

ATM Status Click this to view your DSL connection’s Asynchronous Transfer Mode

(ATM) statistics. ATM is a networking technology that provides high­speed 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.
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.

ATM Loopback
Test

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 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.

Click this to view statistics about the DSL connections.
noise margin downstream is the signal to noise ratio for the

downstream part of the connection (coming into the ZyXEL Device from
the ISP). It is measured in decibels. The higher the number the more
signal and less noise there is.

output power upstream is the amount of power (in decibels) that the
ZyXEL Device is using to transmit to the ISP.

attenuation downstream is the reduction in amplitude (in decibels) of
the DSL signal coming into the ZyXEL Device from the ISP.

Discrete Multi-Tone (DMT) modulation divides up a line’s bandwidth into
sub-carriers (sub-channels) of 4.3125 KHz each called tones. The rest of
the display is the line’s bit allocation. This is displayed as the number (in
hexadecimal format) of bits transmitted for each tone. This can be used
to determine the quality of the connection, whether a given sub-carrier
loop has sufficient margins to support certain ADSL transmission rates,
and possibly to determine whether particular specific types of
interference or line attenuation exist. Refer to the ITU-T G.992.1
recommendation for more information on DMT.

The better (or shorter) the line, the higher the number of bits transmitted
for a DMT tone. The maximum number of bits that can be tr ansmitted per
DMT tone is 15. There will be some tones without any bits as there has to
be space between the upstream and downstream channels.

Click this to reinitialize the ADSL line. The large text box above then
displays the progress and results of this operation, for example:
