  • 4. Major Operational issues
    • No correlated view of customer, service and network resources.
    • Increasing need to churn out commodity based (voice & data) services along with premium content based services instantly.
    • Fragmented OSS / BSS islands without common or single view of the operational ecosystem.
    • The ‘Multiplicity’ effect without standard naming conventions.
    • Lack of end - to - end visibility leading to poor control.
    • Resource utilization is not optimized.
    • Strict SLA conformance
  • 5. Introducing InstaServ
    • Application communication framework via a common metamodel based on SID business entities.
    • Use case driven model based on the e-TOM guidelines.
    • Defines processes through interfaces.
    • Standard Nomenclature to reduce data mapping issues.
    • SOA realization through Web Services.
    Refer to the embedded document for a brief introduction to Insta Serv
  • 6. Motivation
    • Need to have a single correlated view of the business entities viz. Customer, service, network, agreements, roles etc.
    • To de-couple business processes from internal software code.
    • Need to have a common interface for speed up service delivery and maintenance.
    • Tuning existing systems to e-TOM business process recommendations and mapping them to the SID nomenclature.
    • Need to implement a SOA based architecture to implement NGOSS contract based guidelines.
    • Use case based implementation versus simple product implementation and integration approach.

  • 12. USE CASE - Service fulfillment
    • The customer provides a Service Order.
    • Initial Pre Qualification and a limited local loop testing is carried out to determine feasibility of service.
    • Inside plant DSLAM ports are assigned to the service request.
    • Jumpering at the MDF is done to connect the local loop to the DSLAM.
    • ATM PVC provisioning and port activation is done manually by the NOC team through the vendor specific NMS and EMS.
    • Once the ports have been activated , notification is sent to the customer.
    • After customer acceptance , notification is sent to the billing group to start billing for the activated service.

  • 16. Use Case : Service Assurance
    • Fault Manager displays a network level fault with a certain degree or a customer trouble ticket is assigned to a NOC professional..
    • NOC professionals view the problem detail and determine the existing network topology and isolate the problem.
    • Run troubleshooting procedures to resolve the network problem through vendor specific EMS and NMS.
    • Once the problem has been resolved or the network fault has been repaired the trouble ticket is closed and the customer is informed.
    • If the problem cannot be solved directly by the NOC team then it needs to be staged to other teams or field engineers.
    How the Service Provider perceives Service Assurance function Network oriented & Reactive process !
