The second page of the ATM statistics is dependent whether the
ADSL or G.SHDSL interface is active on the Quadro.
Correspondingly, the ADSL or G.SHDSL page will be displayed.
For ADSL interface, the ADSL page has the following subpages:
The Common subpage displays the ADSL device
characteristics on the first line: type, version number and the
serial number.
Operational mode displays the supported Annex type as
detected by the modem after connecting to the central.
The Driver Condition displays the internal status of the modem
driver. It should be active for normal modem operation.
The Link displays the ADSL link status and the internal status of
the modem connection is displayed as link value.

The Performance subpage indicates an overview of available
bandwidth, noise levels and events. It provides information
about the line quality and for detecting line problems. The
information below is displayed for both Upstream and
Downstream.
The Capacity Occupation represents the ratio of the achieved
linerate over the attainable linerate.
When the modem is up, Noise Margin indicates the realized
noise margin. When the modem is down, last measured noise
margin is displayed.
The Output power gives the measured total output power
downstream and upstream. When modem is down, last
measured power is given.
The Attenuation is measured upon activation. It represents the
difference between the total received power and references
transmit power. Received signal power in dBm is the sum of the
received power of all tones. Reference transmit signal power in
dBm is the allowed transmit power taking into account power
cutback transmitted over the full band. A value of 31db reported
by ATU-R should be interpreted as 31db or higher.
When the modem is up, Bitrate interleaved and Bitrate fast
fields indicate the actual ATM bitrate (without overhead) for the
upstream / downstream fast or interleaved channel data flow.
Counters and Defects indicates the counters for cells, events
and anomalies of the fast (f) and interleaved (i) data flow.
Events – bit errors that do not effect the device performance:
FEC – Forward Error Correction.
Anomalies – errors that effect the device performance:
CRC – Cyclic Redundancy Check;
HEC – Header Error Correction.

The Carrier Load subpage indicates an overview of the usage
of the carrier signals frequencies.
