ADC SWD4573I1 Manuale Utente

From the 

::alarm=>

 prompt, type the new command in the following format then press 

 to create a new SDSL cell alarm profile. The profile is automatically assigned the next 

available index number in the SDSL cell alarm profile table.

<threshLOSS> <threshLOCD> <threshSLOCD> <threshSNR>

<threshLOSS>

The loss of signal seconds threshold. When the number of loss of signal seconds in the 
current 15-minute data collection interval exceeds the specified threshold, the loss of signal 
seconds alarm is activated. Loss of signal seconds are seconds during which the SDSL cell 
line is incapable of transmitting or receiving data and all data is lost.

<threshLOCD>

The loss of cell delineation threshold. When the number of loss of cell delineation seconds 
in the current 15-minute data collection interval exceeds the specified threshold, the loss of 
cell delineation alarm is activated. Loss of cell delineation seconds are seconds in which 
some cells transmitted during that second were lost.

<threshSLOCD>

The severe loss of cell delineation threshold. When the number of severe loss of cell 
delineation seconds in the current 15-minute data collection interval exceeds the specified 
threshold, the severe loss of cell delineation alarm is activated. During a severe loss of cell 
delineation second most of the cells transmitted during that second are lost. 

<threshSNR>

The signal-to-noise ratio threshold. When the signal-to-noise ratio margin drops below the 
specified threshold in the current 15-minute collection interval, the signal-to-noise ratio 
alarm is activated. SNR margin is a measure of signal quality indicating how much margin 
can be dropped before the number of bit errors exceeds the ratio of 1x10

-7

 errored bits per 

bits transmitted.
