CDR Sample for Electrical EngineeringFull description
Data and functionality are two primary aspects of systems. Unfortunately, there is a mental gap between these two aspects. Therefore, nowadays many are looking for the corresponding research and development fields as quite distinct with different ter
Normalization CDR General information Before come into detailed description some clarification regarding CDR (Call Details Record), CDR format etc needed. Here in Aircel Limited Ericsson switch has been used and the CDR format for Ericsson switch is ASN.1 Format. ASN.1CDR format is normally supported by the TAG-LENGTH-VALUE combination. The CDR is started with the conventional CDR starter A0 and it is followed by the length of the CDR. After that the different CDR types are identified by the CDR Tag (A0 for transit, A1 for originating etc). The different fields appear in the order of Tag first then the length of the field and that follows the field values. The CDR Types, which are actually may generated here in Aircel Limited, are: a) b) c) d) e) f) g) h) i) j)
0xA0 0xA1 0xA2 0xA3 0xA4 0xA5 0xA6 0xA7 0xA8 0xA9

Length Calculation: ASN.1 Format follows this logic for finding length of data. If next byte of TAG is 0x80 or 0x81 then next one byte is for length, If next byte of TAG is 0x82 then next two byte is for length, If next byte is other than those value the that byte itself is for length. Here is an example for reading HEX CDR: CDR Tag :: A0 82 ==> Length of Data ==> 014C ==> 332

Inside the program, we calculate according to tag length value and then converting the particular values to ASCII format with the c++ functions the we are sending it to different deliverable files.
