Multichannel PRA
6.6 Calls statistic (CDRs)
The statistic functions (CDR = Call Detail Record) are intended for the storing of call
data. Incoming and outgoing calls are registered. Due to the limited memory space
in the Multichannel PRA, call data can only be stored without loss of data until the
available memory is used up (CDR memory is 512kByte, can hold approx. 8000
CDRs. With a call every 2 minutes on 30 channels (15 CDRs/minute) this lasts
around 8 hours).
The remote service PC with installed coM.s.a.t PRAC software (e.g. the central
office) should then build up a connection to the coM.s.a.t Multichannel PRA and read
out the statistical data.
Statistic data can be read out by clicking the “Statistics”/"Load Statistics" menu
entry.
It is recommended to read out the CDRs periodically by setting the refresh interval in
the parameter dialog ("Statistics"/"Parameters") to a value greater than 0, e.g. to 600
for refreshing the CDRs every 10 minutes.
The read-out data is stored in predefined files. The file name is composed by the
Identification string as entered in General Parameters and the date of the CDR’s to
store. For each day a separate file is created.
The path to store the CDR files is selectable in the “Statistics/Parameter” dialog.
The read-out data is stored in CSV format to be easily processed with standard worksheet
applications like Microsoft Excel®.
