Example 2: Measurements From a Batch File
This example describes only the command line functionality to acquire the
signals with a system under test. For an example of how to use the
command line option to analyze files, please refer to the OPERA™ user
manual.
Again, you will have to take care that the telephone line is looped back on
the far end, so you will get your signal to the terminating line. Connect both
trunks of the E1/T1 interface board to the SUT. As described in the example
in 6.1, we have to configure the E1/T1 interface using the OptiConf™ dialog,
before we run the automated measurement from the script file. In OptiConf™
™, we select the protocol type "E1_MFCR2", the protocol version
"Mfcr2_ITU" and the subversion using 5 digits without ANI function (see
Figure 6.1). Since all the other parameter values are fine for our example, we
leave them as they are and start the initialization process by clicking on the
Apply button.
Note:
Only run the batch file after you have received the message
that the initialization process has been finished. Only then the
board configuration is available for the automated execution.
We now want to use the same settings as described in Example 1. We will
perform a loop measurement, the number to dial is "12345", the reference
file is taken from the location "C:\programme\opera\DefaultRefFile.wav",
destination directory is "D:\test#E1_T1". The originating line index is chosen
corresponding
to
E1_MFCR2_ITU_5Digits_no_ANI Port 0 BCh 0" and the terminating line
index would then be 34. We will use the
terminating line. The correct offset value is then 30 in accordance with the
chosen E1 protocol. Thus, the correct command line will be as follows
(should be written in one line in the batch file):
Opticall /Exec –Loop –OriginatingLine 4 –Mirror 30
–Phonenumber 12345 –RefFileOrigin
C:\programme\opera\DefaultRefFile.wav –
RefFileTermination
C:\programme\opera\DefaultRefFile.wav –
DestinationPath D:\test –Root E1_T1
After the batch file has been executed, the resulting files will be
D:\test\E1_T1-Line4.wav (to be used for PSQM or PESQ analysis) and
D:\test\E1_T1-Line34.wav (for Echo analysis).
