Service Models and System Architecture

To operationalize nextep solutions online requires five basic components:

Data process boxes - these range widely in sophistication and cost, from "dumb" boxes that collect and digitize data and route them to a software application loaded on a local PC work station, to "smart" boxes that perform complex calculations prior to data transmission to the server.
Medium of transmission - once data are collected and converted by the boxes they are transmitted to a server via telephony (land line or mobile phone), Ethernet or high-speed communication lines such as DSL, T1/T2, cable, etc.
Database server - data are transmitted to the database and stored in structured tables. Nextep uses an open-source mySQL server for this purpose, which resides at the nextep office. However, a database server can be set up on-site at the client facility for control and security reasons.
Application server - nextep uses a Linux server to support the application. Like the database, the application server can reside on-site at the client location.
The application - the graphical Web-accessible interface that the user manipulates to view data and information. Nextep has built their application using open-source Java software (Tomcat).

CT BOX GSM

The Collect & Transmit BOX is a data-logger for pulse-based meters (any fluid)
This box gather data at regular time intervals ( which can be set/changed remotely), saves up to 1 28K of data in its memory and send the information via GSM

Is a local data-logger to process any digital or analog signal. This box collects data at regular time intervals (remotely programmable), which is then transmitted via a local network and the Internet
