Electronic Folder Interface (EFI) is a messaging application in order to provide Electronic Disability (eDIB) effort that facilitates and regulates the communication between all existing disability components/systems through out the country and the Electronic Folder.

The flow of information between the various components/systems is achieved through sending and receiving of WebSphere Message Queue (WMQ) messages called transactions using Extensible Markup Language (XML) format. EFI validates and processes the transactions sent by the disability components/systems. Through EFI, other disability components/systems can create, read, update, and delete messages in the Shared Data Repository (SDR).

The Application LightSpeed gets the requests for new services offered by SBC. The major new services are HSIA and IPTV. These request come from External Clients Yahoo through SDP. SDP (Service Delivery Platform) is a component responsible for forwarding service and account related provisioning requests, update of customer account and billing information. Service attributes changes to downstream systems including SBCIS. Upon service registration SBCIS is responsible for forwarding the registration notification to SDP the service requests are initially provisioned for the initial requests and then they are given member privileges after they request for registration. This is a multi-tiered application which is in compliant with J2EE architecture and uses design patterns like Business Delegate, Session Façade, DAO and Value objects. Interaction with Yahoo uses session façade and the database access is obtained using value objects Involved in the Registration process for Lightspeed. The process of Registration is mandatory for customers who wish to use their HSIA / IPTV service. When the customer orders HSIA or IPTV services, SDP notify MPS on due date that the member’s services are eligible for activation. MPS receives these records and puts them into the MPS Holding Table so that they are available at the time of Registration. Once the member enters the Registration website, the Registration process will try to determine the identity of the customer.
