Performance Verification System - realWORX WEB allows operators to confidently roll out RF-sensitive new services like High-Speed Internet (DOCSIS 3.0),  VoIP, HDTV, and Video-on-Demand

The realWORX WEB Performance Verification System allows operators to monitor return ingress levels, analog signal performance, as well as QAM performance and statistics from many nodes using any browser interface. realWORX WEB is run from a centralized server/s and can be scaled to meet any size monitoring system requirement.

realWORX WEB compares RF performance against user-set limits and activates an alarm when signal impairments are detected. The system sends alarm notifications by email, pager, or cell-phone, and can report to the NOC via SNMP trap.

With Sunrise Telecom’s unique AT2500HMQ broadband spectrum analyzer at its core, realWORX WEB can detect transient and low level RF impairments invisible to competing systems. realWORX WEB also integrates both upstream and downstream RF quality measurements in one system, which results in decreased costs of hardware, training and support. With realWORX WEB, tests that had once been complex and time-consuming can be performed routinely, automatically and consistently.

Key Features and Benefits

• Monitors upstream return path spectrum
  • Monitors RF signal, Ingress as well as Laser non linear operation above 65MHz
  • Monitors and Alarms on Laser Clipping and Common Path Distortion Events (CPD)
  • Sends real-time return path spectrum traces from multiple analyzers to multiple field personnel simultaneously (using realVIEW and accessible from a Web browser, Client software on a PC, CM2000 meter in the field)
  • Fast scan rate (2 ms) and high-sensitivity (-65dBmV) measurements detect Common Path Distortion and other impairments before it affects service
  • New improved 2X speed, now monitors 80 nodes per second
• Monitors forward path downstream channels
  • Monitors Analog and Digital QAM measurements (levels, frequency, Channel power , MER, Pre and Post BER, EVM, ENM, etc...)
  • Real-time remote spectrum view & analysis
• Monitor digital carriers such as DOCSIS/CMTS Channels, high speed Internet, digital TV, VOD and VoIP to detect impairments before customer service is affected
• Supports multiple analyzers/switches, no limits on system size
• Integrated ingress, analog, and QAM verification platform saves money on hardware, training, and support
• Automatic alarm notification by email, pager or cell-phone
• SNMP Trap notification to a remote Network Operations Center(NOC)
• Store and view historical RF measurements for trend analysis
• Modular and scalable distributed architecture

Solution Architecture

The realWORX WEB system is based on Sunrise Telecom Broadband’s AT2500HMQ series of headend spectrum analyzers. The realWORX server can control multiple analyzers and monitor the performance of several hubs. The analyzers monitor multiple reverse or forward RF test points by means of RF switches. Using Sunrise AT1600 family switches, up to 256 nodes can be monitored from each analyzer.

realWORX WEB employs a modular software architecture, with a separate software module for upstream ingress and downstream performance measurements. Operators can choose to buy only the modules needed for their particular testing requirements.

The realWORX solution consists of:

• realWORX WEB system comes preconfigured on a high performance server
• Database redundancy is handled by dual high capacity hard drives running in RAID 1 configuration
• Power Supply redundancy is handled by dual power supplies in each server
• AT2500HMQ and AT2500HM spectrum analyzers located at the headend, hubs or VHO, VSO’s to be monitored
• AT1600 RF switches co-located with the analyzers to connect a single analyzer to the network nodes
• Additional realWORX WEB servers add a scaleable solution regardless of system size
