Project: Integrated Switch Provisioning System

The tools used by this client for provisioning switches were relatively primitive, required significant subject-matter expertise to use and did not produce acceptable levels of reliability or performance.

These projects were aimed at replacing low level provisioning tools for switches manufactured by three different vendors with a web user interface, integrated tool with a common user interface and workflow for each of the switch types. In addition to improving the interface and the workflow the new tool was tasked with reducing reliance on switch engineers, improving accuracy, and timing.

ASIX’s Role:

Initially, ASIX consultants worked on a team made up of Client and ASIX employees. For; design, construction, implementation, testing, and debugging of the version for the first brand of switch, ASIX led most design sessions, and ASIX designers and implementers took on many critical aspects of the project. Once the first version was released, ASIX was asked to expand the system to provision the other two brands of switches and add some extensions to the first brand. ASIX developed the preliminary design and the initial estimate and went on to develop the detailed design, develop the code, document the application, and build the test scripts and databases. The ASIX team supported testing, the First Office Application (FOA) and the training of end-users.

Application Architecture:

Integrated Switch Provisioning System High Level Architecture

The system consists of interactions between sub-system that managed a database of subscribers with roaming privileges, a Provisioning System front end User Interface and the Provisioning System back end Server Components. Users interact with the front end via a web interface. The web server resides on the same server as the back end. The front-end interface interacts with the subscriber database and with the back end scheduler via FIFO commands. The back end components interface with each other and with the database. The component architecture is shown below:

Application Benefits:

The Integrated Switch Provisioning System design simplified switch provisioning processes, which reduced the need for subject matter expertise and improved provisioning speed and reliability.

Methodology:

We used the Client’s standard gating and development methodologies in this project.

Technology:

• UNIX
• Object-oriented Perl
• C++
• Oracle data base
• Apache Web Server.

Outcome

The Integrated Switch Provisioning System met all defined objectives and was praised for the detail of its design and the usability of its documentation. The expanded system which was outsourced to ASIX was completed within 5% of the final budget.
