JeTSI is a Value Added Reseller for the Space Link Extension (SLE) SW products developed for the European Space Agency (ESA) and provided as commercial products by Vega.

A commercial SLE-API application can greatly reduce the cost and risk associated with integrating your existing or new product with the SLE protocol as well as insulate your code from changes or additions to that protocol.

The ESA SLE includes both the SLE User and Provider nodes, including the SLE-API for user applications to connect up to the SLE interfaces. The CCSDS Recommendations governing the SLE SW products are:
