ROC Data Integrity Management - Leased Line Cost Recovery

Transcription

1 White Paper powering the ROC ROC Data Integrity Management - Leased Line Cost Recovery Consider this What is your monthly bill for leased lines? Calculate 5% of this amount Now multiply this by 12. Would your business be interested in saving a MINIMUM of this amount every year? Explore how ROC Data Integrity Management can help you capture these savings through Leased Line Cost Recovery.

2 Introduction For many mobile operators the cost of leased lines and off -network transport is a significant operational expenditure. Reconciling these costs against actual service status can be extremely difficult. Subex drives the guesswork out of leased line cost reconciliation with the ROC Data Integrity Management Leased Line Cost Recovery solution, part of its Subex Fulfi llment Solutions suite. This unique solution set automates critical steps in service creation and delivery, while ensuring all OSS/BSS functions are synchronized with the service delivery process. This is why leading service providers including BT, Verizon Wireless, Sprint, Telstra and many others rely on Subex solutions. What is Data Integrity Management? Inaccurate or dirty data represents a longstanding problem in the telecommunications network operations environment. Provisioning errors, inefficient capacity utilization, stranded assets and leased line cost overruns all stem from data integrity problems. Preventing these problems is why we have made managing data integrity an essential component of our Subex Subscriber-Centric Fulfillment strategy. ROC Data Integrity Management is used by leading Tier 1 carriers to reconcile OSS/BSS databases, comparing them with the actual existing network and services. As the industry s pioneering OSS/BSS Data Integrity (DIM) software system, ROC Data Integrity Management represents the most cost effective and efficient way to manage the quality, accuracy and consistency of data that is essential to many business-critical processes. ROC Data Integrity Management features: The industry s most advanced infrastructure and service discovery engine A highly flexible reconciliation engine for comparing different data sources and reconciling them To support Cost & Revenue Assurance processes, ROC Data Integrity Management brings network, service and customer data into the equation as a master source to compare against billing, ordering and accounting systems. Controlling the costs of leased lines For mobile operators leased lines are a vital and costly part of the network infrastructure, providing the link between the radio and core networks and often used for the ongoing transportation and interconnect of voice, data and service traffic. So not only can leased lines form a major part of the physical network, they often can make up the largest single portion of the service provider s operational costs. Industry experts estimate that inaccurate billing for leased circuits can equate to as much as 8% to 10% of total leased line costs, amounting to millions of overspend annually. An estimated 80% of all leased line invoices contain at least one error. 02 Subex Limited

3 At the heart, this problem is a data integrity issue, caused by discrepancies such as: How a service is represented in the BSS/OSS, How and if it is billed, How it actually exists in the network. A data integrity improvement project addressing leased line cost recovery for mobile operator focuses on the following areas: Comparison of in-house data sources to in-bound bills 1 1 Comparison of data associated with leased lines discovered from the network, to other in-house data sources The award-winning ROC Data Integrity Management enables carriers to reconcile leased line billing records with their actual configuration and service status within the network. How? An estimated 80% of all leased line invoices contain at least one error. This is often because the in-bound bills for the leased circuits can be out of synchronization with the actual lines that are provisioned in the network. ROC Data Integrity Management automates key steps in leased line bill reconciliation. By investigating circuits with its discovery engine, ROC Data Integrity Management can help to pinpoint areas of leased line bill inaccuracy. Thanks to its ability to conduct discovery at the service or configuration level, ROC Data Integrity Management can detect port-level discrepancies and channel-level discrepancies. As a result, you can identify potential overcharges to challenge and find grooming opportunities to optimize and manage the utilization of leased circuits. ROC Data Integrity Management conducts discrepancy management and resolution by sweeping target data sources and the network then conducting ongoing comparisons to detect inconsistencies. This process can be augmented by the patent-pending Discrepancy Analytics function, available exclusively from Subex. Discrepancy Analytics uses sophisticated algorithms to recognize patterns of discrepancies, dramatically simplifying the identification and resolution of large masses of discrepancies. With analytics, large groups of related discrepancies that previously took days or weeks to untangle and resolve can be identified and corrected rapidly. For a large American Operator, Subex recovered the following Total projected LEC/AAV Access Cost Savings Identified for circuits with no cross-connect discrepancies - 118,418 Total projected savings for Access Networks - 4,327, Circuit order systems, planning systems, inventory management systems, etc. Subex Limited

4 Return on Investment In even a relatively clean data environment, a service provider can be overpaying for leased lines representing significant cost to the business. Data integrity projects conducted by ROC Data Integrity Management to identify off -net leased line cost reduction have indicated that large carriers stand to reduce leased line charges by tens of millions of dollars, even if discrepancy levels are a nominal 5%. ROC Data Integrity Management also features powerful reporting functions that enable operators to track key performance indicators for discrepancy management, accurately identifying the continued progress and success of data integrity management projects.
