Celerity - SP

Service Performance

Based on a single directory number or equipment number of a line to be qualified, Celerity SP performs a real-time sequence of tests to determine if a line qualifies for a particular speed or service.

Celerity results support call center sales reducing false greens and false reds, ultimately increasing customer satisfaction, revenues and profit margins. Results can also be used to support service fulfillment, verifying line conditions during the service installation process.

Celerity uses a unique, multi-patented approach to qualify lines using fast, swept frequency analysis for the purpose of detecting faults or impairments to service performance and service/speed binning. To gain access to lines in the network, measurements are made through the voice switch test bus, or alternately can be made through a test access matrix.

Lines can be qualified according to their service capability. Celerity provides the following information per line:

• Service bin – qualification statement for Internet data and video services
• Signal level (loss) – patented single ended technique approximating double ended loss measure
• Home wiring influence – excessive inside wiring relative to shorter lines used for video services
• Noise rejection – ability of a line to reject interference from neighboring lines in the same cable bundle

False Reds
Celerity SP reduces false reds; lines previously thought to be incapable of supporting DSL but could in fact support service. Celerity has been proven to recover up to 35% of lines previously disqualified by other existing approaches.

False Greens
Celerity SP reduces false greens; lines incorrectly classified as being ready for DSL but in fact are not. Celerity reduced the number of false greens by 4% in field trials.

Celerity SP can be combined with Celerity XS to identify DSL affecting equipment and terminations.
