ATM Fast/Interleaved bit rate: Is the current maximum bit rate available for ATM 
Fast or Interleaved path. 

 

Only one path at time is available on the ADSL line, so the other 
value will be zero. 

ATM maximum line rate: Is the maximum theoretic ATM bit rate, without overhead, 
available on the line assuming there where no ATM or rate adoptions limits. 

Relative Capacity: Is the relative capacity occupation of ADSL line. This parameter 
represents the ratio of the achieved line rate over the attainable line rate, expressed 
in percentage. Both line rates are the sum of ATM speed rate and all the overhead 
data. 

Noise margin: Is the realised noise margin. 

Attenuation: Is the line attenuation on entire ADSL bandwidth, it‘s the difference 
between the reference transmitted signal power and the received power of all tones.  

Output power: is the total output power measured in upstream and downstream 
sides.  

 

All data are reported for downstream (DOWN) and upstream 
(UP) link. 

 

In order to save test results into the device memory. 

 

Prints the test results. 

With this test it’s possible to verify if the ATM layer is working fine until the first ATM 
termination unit. This test allows the OAM cells test with Response time (ms), errors 
and statistics. 

The display shows the Test Status (running or not). 

► 

The LED STATUS is OFF if no test running, is ON (green) during regular test 
running, is ON (red) when an error/alarm occurs.
