Configuring a Wireless Modem Card
ALPHA DRAFT - CISCO CONFIDENTIAL
Example
The following example will configure a histogram specification. The histogram collection will start
as soon as the command succeeds. It will collect a histogram for interference noise ratio. The
histogram will be collected on dsprx2a with starting bin of 2^-4 (a starting ratio of 0.0625), bindelta
of 1 and 32 bins in total, and no bitshift. It will cycle through the frequency tones for every successive
sample. The collection will continue for 1 hour, reporting data every 30 seconds and keeping the
cumulative histogram.

Use this command to display the details of the histogram specifications currently configured. If none
of the optional parameters are specified then all histogram specifications on the modem card are
displayed.
Unless an error occurs, no notifications are displayed on the console.

NumBins The number of histogram bins to be configured for the collection.
BitShift Specifies the number of bits by which the collected data should be shifted to the right,
providing a mechanism to control overflow of the values in the histogram.
collectionInterval Specifies, in seconds, the interval in which histogram data will be collected.
periodic Specifies, in seconds, how often the collected histogram data should be printed to the
screen. The sum option specifies whether successive histogram sets retrieved from the
hardware should be added to replace the existing histogram data.
Specifying a statistic collection to be periodic effectively reduces the size of the
NumBins to half the possible amounts. The default is periodic. If the interval is 0,
output is generated only at the termination of the collection.
tone Identifies how the histogram sample should be computed when sampling a burst. A
burst contains data samples from N frequency tones.
circulate
Implies successive histogram data samples should use successive frequency tones.
average Implies successive histogram samples should average the burst data over all the
frequencies and use that value.
number Specifies that a particular tone in the burst should be used to report the histogram data.
The frequency tone is passed in as a number specified in the <tone-number parameter.
