Java Developer – Remote work only

 

PROJECT DESCRIPTION:

 

The Access Optimization (AO) project has been implemented by ACELA to integrate several of Verizon’s Networks provisioning systems like, NetPro, F&E, Cameo etc. The Access Optimization application accepts orders from NetPro, F&E and COMS, stores the order in the ICS transient database, and then interacts with:

 

·   The CAMEO application, which determine the optimal path to provision the order. During the determination of the optimal path, CAMEO invokes the CFA Validation routine of the AO application. The CFA Validation routine in turn interacts with F&E, NetPro, TCOMS and Symphony to determine circuit availability.

·   The Symphony application to do LEC Address Validation.

Once A & B are complete, the AO application returns the processed order information back to the originating system. AO application also processes requests from the PSG to do Path Selection, CFA Validation and LEC Address Validation.
