Celerity - SQ
Service Qualification
Celerity SQ provides accurate single-ended pre-qualification of all copper loops in the network, creating a database that bins each line according to its DSL speed or service capability. Celerity results support call center sales and targeted marketing, reducing false greens and false reds, ultimately increasing customer satisfaction, revenues and profit margins. 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 all lines in the network, measurements are made through the voice switch test bus, or alternately can be made through a test access matrix. Lines are tested using the Celerity routine feature, which automatically sequences through all lines in an exchange.
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 SQ 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 SQ 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.
SQ Outputs
The results of Celerity SQ are stored in a data warehouse for integration with service providers’ flow-through provisioning processes, targeted marketing campaigns, etc.
Celerity SQ can be combined with Celerity XS to identify DSL enabling or DSL impairing equipment and terminations.
