Transverse, an open source business solutions company, has launched its open source OSSIBSS platform called Business Logic Execution Environment and Platform, or blee(p). The solution is said to extend the promise of open source computing to telecom operational support systems to leverage better quality, application agility, innovation and lower total cost of ownership. Transverse said blee(p) takes advantage of the newest technology innovations and the most advanced open source projects to deliver an end-to-end telecom back office that is flexible and adaptable to the rapidly changing needs of carriers. It is designed as a fully integrated set of business management services for back office systems. blee(p) services are grouped into business domain structures that provide more than 2,100 services via metaŹdomains. Utilising service-oriented architecture (SOA), these domains are easily extended through a plug-in framework, allowing a limitless number of business solutions to be assembled in days, instead of weeks or months.
