hi siva_kumar,

Right now I am working for Vodafone australia and Newzland. I will explain about the technology used in here for Vodafone.

• for telecom domains, the most preference is given to processing the data which comes from the Telecom Switches.
• Perl will come into picture in processing all these datas in a specified format and get loaded into DB. we are using informix as Database. Some other clients are using Oracle.
• Telecom switches datas are releases as a XML data, CSV data or Space delimited data. In all these cases perl will play a major role in parsing these data before these datas are getting loaded into DB.
• In Telecom Projects most of the GUI part is developed using Java. Perl is not used there.
• The Technology Packs like nokia,ericsson blahblah are the heart of the telecom products. These Technology Packs are Tested using Perl Only.
• For DataValidation Test Perl scripts are used extensively.
• Once you come to Telecom Domain you will come to know the concepts of Counters and KPI. These values are validated using Perl once it is loaded into DB.
• To produce backend reports perl scripts are used.
• If you are having hands on experience in perl it would be more helpful in Telecom Projects. From my experience I am sure that you are not going to write a perl script for Telecom Projects from the scratch. Keep that in mind.

Best wishes for your new work, hope you will go great.
