  1. Challenges with DSL Deployment Arabcom 2004 Presented by: Dave Mehta

  2. Global DSL Subscribers by Region

  3. Global DSL Subscribers by Region • Record Growth for Broadband DSL in 2003 • 2003 - 28 Million new subscribers, 78% annual growth • Global total reaches 64 Million

  4. Growth of DSL – Middle East / Africa

  5. Growth of DSL – Middle East / Africa • MEA now has + 500K subscribers • Growth in 2003 - 178% • Deployment Growth is well above Global Average of 90%

  6. Technology Hurdles for DSL • Global deployment has proven that DSL Service will be affected by any or a combination of the following: • state of the local loop • spectrum compatibility • bridge taps • environmental effects • equipment failures • in-home wiring

  7. DSL Deployment – Service Provider Challenges • Provisioning challenges • Extracting new revenue from existing copper plant • Cost effective qualification of the local loop • Customer Service and Technical Support • Binder Management of Deployed xDSL Services • Differentiation of Service Offerings – Revenue Protection • Service Level Agreements (SLA’s) • Interoperability • Self Installation

  8. Reduce truck rolls -> Accelerate deployment time -> Rapid Time to Revenue Deploying DSL Profitably • Typical Service Provider goals for DSL deployment: • Revenue Generation - Increase # of users – the cost to deploy a new user cannot exceed the revenue generated by that user for longer than a reasonable period • Decrease capital expenses for equipment • Reduce costs required for supporting and maintaining equipment • Reduce truck rolls • Acquire cost-effective DSL test solutions

  9. Test Strategies for DSL Deployment A combination of 2 testing methodologies are required to ensure a profitable DSL Deployment: • 1. Centralized DSL Testing • Single-end, CO based DSL test system • Copper (local loop) pre-qualification • xDSL Service pre-qualification, provisioning and troubleshooting • Fault diagnostic and location • Service Testing into the network • Service testing out to the End User (customer)

  10. Test Strategies for DSL Deployment

  11. Test Strategies for DSL Deployment A combination of 2 testing methodologies are required to ensure a profitable DSL Deployment: • 2. Portable Test Instruments • Single-end & end-to-end xDSL testing • Copper (local loop) troubleshooting and maintenance • Testing at multiple access nodes • Extremely low cost testers for DSL installation • Fault diagnostic and location

  12. Test Strategies for DSL Deployment Typical usage of Portable DSL test sets:

  13. DSL Management ILEC POTS POTS Switch X POTS xDSL & Data DSLAM Data X MTAU MTAU Testhead DMU EMS EMS OSS Loop NEI I/Fs Management Test Engine Rapid Time to Revenue • Rapid Qualification • Bulk loop pre-qualification • Drastically reduce truck rolls (locate bridge taps and load coils) • Increased customer opportunities (8-10%) • Installation Support • Rapid footprint (bandwidth) capture • Customer care differentiator • Unbundled loops • Per use fees for loop qualification • Monitor Service Level Agreements • Cost Reduction • Reduced skill set needed • Reduced testing time • Independent of DSLAM type

  14. Business Drivers Key considerations around the purchase of a DSL test solution are: • Revenue generation • Don’t only offer one speed of service, move to graded service. • Don’t limit deployment to customers within a specific circumference of the exchange. • Mass qualification or targeting of customers. • Local Loop Unbundling, lease qualified loops to Alternative Operator • Cost reduction • Single Ended Loop Qualification (SELQ) benefits. Reduce Truck Rolls. • Consolidate multiple data bases of customer information for installs and service requests. (OSS consolidation).

  15. Business Drivers…cont. • Revenue protection/customer loyalty • Offer broader range of services, graded service • Go beyond the defined circumference limit around the exchange office. Larger market share. • Program OSS test agents for SLA support of the local loop. • Foot print comparison to expedite diagnostics of loop and DSL performance. • Time to market. Reduce installation & provisioning & service cycle time. • Ease of setup and use (skilled staff required?) • No incremental training required other than that needed for OSS GUI. • Configuration expertise of system. Optimization of the application to it’s deployed environment. • Remote software upgrades

  16. Loop Qualification • Automated, Single Ended Loop Qualification Process • Loop Testing: • Metallic Faults • Loop Length • Load Coil Detection • Bridge Tap Detection • Wide Band Noise • Bandwidth Prediction • Upstream and downstream speeds • Batch Loop Qualification • Spectral Disturber Identification

  17. Service Providers need an application that can perform reliable loop diagnostics for both qualification & maintenance! Benefits of DSL Testing • Deploy more services faster • Reduce DSL maintenance and operational costs - increase revenues • DSL test solutions have a proven short term ROI • Rapid fault location and diagnosis on BOTH copper circuits and digital services • Qualify ALL loops for xDSL services – don’t miss potential subscribers
