Features and Benefits

DCC boxed has been designed to support your testing needs. Some of the key ways it does this is through being:


You can experiment in ways you can’t in a regulated environment, allowing for issues to be found before ‘live environment’ testing.


You can easily conduct testing in any location that's suitable for your needs, making this highly accessible.


You can mix a combination of emulated and real devices to suit different scenarios, allowing for more extensive early experimenting, saving you time.

How can DCC Boxed help?

Following extensive engagement with customers and industry, we’ve learnt about the different ways which an enhanced version of the GFI tool could support many use cases. Here are some examples of how DCC Boxed can benefit your business:

Enable testing of new versions of Great Britain Companion Specification (GBCS)  and DCC User Interface Specification (DUIS)

DCC Boxed enables users to be informed about new versions of DUIS or GBCS, by interacting with these and understanding system or process impacts in advance of the changes occurring in live. This can enable the possibility of early bug identification and resolution.

Used to support your smart metering training needs

DCC Boxed will enable users to conduct better, interactive training on what the smart metering ecosystem is and how it works – it can even help train smart meter installers! The whole smart metering supply chain and partnering firms can use the representative systems, with their products to show their interactivity. Conducting training against a system representative of DCC rather than an approximation will be more fruitful.

Study and development of GBCS Devices

DCC Boxed will enable thorough understand of the role of DUIS & GBCS for the smart metering network, allowing devices to be more efficiently and smartly developed and triaged, with fewer issues and higher quality outcomes.

Demonstrate end-to-end communication with the Smart Metering Implementation Programme (SMIP)

DCC Boxed will ensure that stakeholders understand the full ecosystem and its component parts​, as well as how they interactive with each other and the various sequences of activity.

Facilitate new devices and product testing​

DCC Boxed will enable new types of devices and solutions to be realised for customers​ via a more extensive environment for development and early testing.

Support analysis when assessing impact of changes on the end-to-end system​

DCC Boxed will support analysis for when changes do occur, ensuring that users are better prepared to manage changes effectively, such as new releases of GBCS standards.
