Head end system architecture.

The system provides a number of important functions that. A head end system is hardware and software that receives the stream of meter data brought back to the utility through the ami. Basically ip headend is a headend that runs on internet protocol. The iptv head end includes solutions to acquire process encode and manage video.

This head end software is the key component in end to end automatic metering and is ideal for grid metering as well as lt consumer metering and demand side management. The basic architecture of a digital catv headend. Aia may design appropriate architecture for providing end to end metering solution. Aia is free to decide upon the best solution out of all the available options.

Upstream spectrum varies greatly between cable plants. Head end system hes d meter data management system mdm e web application with updated on. However the entire responsibility of fully functional ami system shall rest with one. A headend facility may be staffed or unstaffed and is typically surrounded by some type of security fencing.

Note that if their multiplexer is configured with 4 outputs 4 separate scramblers will have to be installed increasing the cost of digital headend vary substantially. Sync 5000 is a high end meter data acquisition system that performs amr ami data analysis in an integrated application base. Resultsfrom the sgig program executive summary advanced metering infrastructure ami is an integrated system of smart meters communications networks and data management systems that enables two way communication between utilities and customers. In ip headend we receive every signal in ip and gives ip output.

Cenelec and etsi in the field of measuring instruments for the development of an open architecture for utility meters involving communication protocols. Sending data reliably upstream is a critical issue. Head end systems may perform a limited amount of data validation before either making the data available for other systems to request or pushing the data out to other systems. In most cases the metering company is the responsible dso.

4 ami and customer systems. Head end system the head end system hes also known as meter control system is located within a metering company network. In ip headend each device is controlled by ip from one server. The cost ofthe scrambler can vary very widely depending on the scrambling system used.

Designing a robust upstream architecture requires balancing system parameters establishing subscriber data requirements and configuring the network to support those requirements. The building is typically sturdy and purpose built to provide security cooling and easy access for the electronic equipment used to receive. A cable television headend is a master facility for receiving television signals for processing and distribution over a cable television system.
