Utility DNO’s

We work with a variety of utility DNOs (Distribution Network Operators) to provide remote monitoring facilities over UTMS / LTE networks. We’ve worked directly with our OEM partners to integrate a variety of functionality supporting the utility industries’ unique set of requirements.

We have now successfully deployed over twenty thousand routers throughout the UK between multiple critical infrastructure providers, giving us a plethora of knowledge in the area.

Replacement Applications

PSTN Replacement

PSTN is used by utilities to retrieve telemetry data for operational and governance purposes whilst also providing remote access to SCADA and HMI systems.

Due to the rise in internet usage across the utility market, it has meant the legacy PSTN network is no longer a viable option for communicating voice and data. The Public Switched Telephone Network or PSTN will reach the end of life in 2025, leaving Utility providers who utilise the network at risk of losing network visibility and management.

Because of this risk in collaboration with our OEM partner, we have formed a solution that seamlessly integrates within a PSTN network maintaining connectivity utilising cellular networks with support for fibre and DSL connection. We have also implemented end-to-end Encryption, SSL through GRE over IPsec, Stateful Firewall features and intelligent control/failover protection.


Paknet Replacement

Launched in 1990, Paknet provided a data-only network using cellular radios as endpoints. It was used widely for applications such as burglar alarms through to network monitoring on critical infrastructure.

Due to the age of the technology and upkeep costs, the current network owner Vodaphone took the decision to shut down the network by mid-2022 leaving subscribers to replace equipment or integrate a solution. In the case of some utility networks, this could be in the tens of thousands of locations.

To mitigate this risk we have worked closely with our OEM partners to develop a Paknet emulation feature providing a plug-and-play solution for integration into legacy networks, Replacing the Paknet link with a low-cost cellular solution.

Read our case study below to find out how we have supported UK Power Networks in their Paknet Replacement Programme.

Case Study


Cherry & White work closely with UK Power Networks on their critical infrastructure network across multiple contracts, which cover over 19 million people (8.3 million homes).
Together with our partners, we developed a cost-effective, reliable solution to replace outdated Vodafone Paknet Pads across the UKPN network. By integrating Paknet emulation onto a cellular router using UMTS/LTE networks, we seamlessly modernized their legacy SCADA equipment.

Case Study

Western Power Distribution

We have supplied critical infrastructure network solutions to Western Power Distribution since 2005, and a close working relationship continues today.
Among the numerous projects we’ve undertaken for WPD, one of our key responsibilities was to enhance the resilience and security of their existing fibre optic network. This was achieved through a meticulously managed, multi-stage implementation process of upgrading their PDH and SDH networks.
