Project Name: NCR @Your Service- Global Incident Management
Company: Tata Consultancy Services
Client: NCR CORPORATION LTD.-USA
Description:
NCR @ Your Service Global Incident Management (GIM) provides a means for customers to view create and update NCR service requests. This solution supports multiple Managed Services offers by providing customers a Web based method to manage their Service Requests. GIM enables service requests to be viewed that originate in incident management systems Dispatch-1, Global Enterprise Management System (GEMS), Gasper ATM Incident Management (GATMM) and Oracle Enterprise Services (ES). GIM enables service requests to be created and updated in Dispatch-1, GEMS, GATMM and ES.
Each GIM user has a profile that controls access to functionality, restricts the customer and service request data to which the user has access and records user preferences.
GIM can display a graphical view of the status of a customer’s ATM/Kiosk network based on GATMM service request data. GIM profile functionality enables customers to specify the categories of the graphs and associate ATM/Kiosk failure types with the categories.
A GIM application sends e-mail notification of Dispatch-1 and ES service request events to customers who, at service request create or update, requested notification.
GIM provides functionality that maps Product IDs (PIDS) to data which is used on Software service create requests to allow the user to create against an NCR Branded Solution Name instead of a PID or set of PIDs, route the request to the proper Global Software Support (GS2) team and present problem identification questions to capture information regarding the request.

Domain: Telecom
Company: Ericsson India Ltd.
Client: Ericsson Product Development Unit, Netherlands
Description:
Ericsson Composition Engine offers a Service Development Environment (SDE). SDE includes information on how to set-up a development environment using recommended tools, architecture guidelines, an Apache Maven repository containing the platform libraries, Apache Maven archetypes, test kits, examples, and domain components (SS7 domain, IMS domain etc.)

Push Proxy Gateway (PPG)
Domain: Telecom
Company: HCL Technologies Ltd.
Client: Comverse (Israel)
Description:
The MIG Push service enables content providers to deliver content, notifications and content data to a client handset using Push technology. Authorized third-party servers (called Push Initiators or PIs) can send notification messages to subscriber handsets, prompting subscribers to click the embedded links or interactive buttons to view content on specific Web sites or servers.
This service is triggered by authorized PIs who send the messages with message delivery instructions to the Push Proxy Gateway (PPG) using the Push Access Protocol (PAP) Based on these instructions; the PPG delivers the messages to the relevant subscriber clients.
The PPG delivers SMS messages to subscriber handsets via external SMSC servers, which store and deliver them to the target subscriber handsets. A typical message includes both a text message and an optional interactive button or a URL link. When a subscriber clicks the interactive button or the URL that appears in the Push message, the MIG system initiates a browsing session.
The PPG system includes three layers:
The front-end layer includes the PPG units, which perform most of the PPG functionality. The Middle tier layer that include, Java Application Server and Tomcat server that perform proxy services to the backend. The backend layer that includes the DBase.
Most of the logic of the backend was implemented in complex store procedures on the DB. The front-end layer is linear scalable. However, the middle tear and the backend layer can be scalable by 2N by having 2 communication channels/accounts with the SMSC simulator using as a substitute of mobile device.
Environment:
• Java 1.5/1.6, Servlets, Spring, JDBC, JMS, EJB, XML, Apache Ant, Apache Tomcat 5.x as a Web Server, BEA Weblogic 9.2 as an Application Server, Oracle 10g, PL/SQL, Linux 5.1/3.1 as OS, SNMP(TRAP), SMSC, SMPP and IntelliJIDEA 6.0 as an IDE.
