DSL Diagnostics & Management Software
Line Diagnostics Platform (LDP)
Aware’s Line Diagnostics Platform (LDP) is an advanced DSL diagnostics and performance management solution that lets broadband operators take control of their DSL network. Telecommunications operators use Aware’s centralized LDP software to reduce DSL operational costs, extend service reach and improve the quality of their triple-play service. Aware’s award winning LDP solution puts all of the essential DSL management tools – service prediction, line diagnostics, network monitoring and network optimization – into a single, centralized multi-vendor compatible software package for use by customer care, network operations, and field technicians.
LDP consists of four functional software modules that work together to deliver responsive diagnostics and proactive management of the operator’s network.
Service Predictor
LDP Service Predictor (LDP-SP) allows operators to qualify the service level that a subscriber line can reliably support. LDP-SP uses single-ended (SELT) or dual-ended (DELT) line measurements, line performance and stability statistics, and Aware’s Dr. DSL® expert technology to produce service-specific qualification for new customers or upgrade qualification for existing subscribers. With LDP-SP, operators can cost-effectively decide where to upgrade lines from ADSL2+ to higher-bandwidth VDSL2 and which subscribers are eligible for triple-play services.
Line Diagnostics
Line Diagnostics (LDP-LD) provides on-demand, real-time collection of diagnostics parameters for fault identification, root cause analysis and guided troubleshooting. LDP’s Dr DSL® expert technology is used to “x-ray” the line and identify DSL faults, such as bridged taps, shorts, or in-home problems. LDP generates easy-to-understand error codes that segment faults into domains (central office, access network, or home premises) along with the impact of each fault. This enables operators to direct resources to the right place to resolve trouble tickets quickly and cost effectively.
Network Monitor
LDP Network Monitor (LDP-NM) gives operators a network-wide view for proactive management of DSL service problems. LDP-NM continuously and non-intrusively analyzes key performance statistics and classifies the health (stability and quality) of each DSL subscriber, or groups of subscribers, based on service-specific criteria. With LDP-NM, DSL operators can detect service degradation issues and take proactive steps before they deteriorate into service interruptions. Subscriber lines with low performance can be identified for proactive optimization or troubleshooting.
Network Optimization
LDP Network Optimization (LDP-NO), also referred to as re-profiling or dynamic line management (DLM), is the process of proactively fine-tuning DSL profiles on a line-by-line and service-by-service basis to achieve the highest possible stable data rate. LDP-NO uses Dr. DSL expert technology to, determine the optimum combination of DSL parameters (e.g. SNR margin, impulse noise protection, PSD shaping, etc.) and select the appropriate service and spectrum profile. The optimized profile is automatically set via direct access to the DSLAM, element management system, or operator’s provisioning system.
System Architecture
LDP is a flexible, centralized, web-based solution that is easily integrated into an operator’s network. Its scalable, distributed, carrier-class architecture can be situated in the operator’s internal data center or cloud-based secure virtual networks. LDP is designed to interface into an operator OSS through a flexible and standard-compliant northbound web services interface (SOAP/XML). The LDP’s southbound interface is multi-vendor compatible and uses industry-standard protocols to initiate tests and collect diagnostics and stability parameters from DSLAMs and gateway access network elements. All LDP data is archived in the LDP Data Warehouse, providing operators with a rich database that can be used for customized data mining, report views, network quality audits, and trend analyses.
User Interface and Reports
LDP includes a web-based user interface (UI) “dashboard” that is used to execute real-time tests or to schedule proactive testing during an operator’s maintenance window. The UI displays easy to understand error codes that identify the suspected problem, its location, and corrective action. The UI’s web-based reports allow users to views the history of individual lines, nodes, or the entire network.
