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.
hmmm ....let me think what did I said

My look on this as someone in OSS for a telecoms company is that vendors are very reluctant to let you play on servers hosting their systems.
It seems the view is not that it's your server hosting their system so they need to fit to your build but that it's their system that happens to be hosted on your server. They take the view that that Perl module you installed makes the system non-standard and so non-supported.
Some are better than others.
Also some of them implement things in very odd ways. For example one vendors system security doesn't use standard system calls eg getent(), but greps password files. | [reply]

I used to work at a company that did IVR and prepraid cards, we used Perl as a glue language. We processed log files, monitored systems and extracted crap from databases for reports, and so forth. I also ran a small intranet server that used Mason for templating/application platform.
Your lamp work should give you a pretty good background.
