Kings Secure Technologies (KST) has worked in partnership with Post Office Ltd since 2011, providing a range of intelligence-led security services.

In light of the imminent discontinuation of Public Switched Telephone Network (PSTN) services by December 31, 2025, Kings Secure Technologies is at the forefront of a significant initiative. This initiative involves the comprehensive upgrade of the Post Office’s network infrastructure, covering more than 7500 branches, aiding in their transition to advanced Fiber to the Premises (FTTP) or Fiber to the Cabinet (FTTC) connections.

The Challenge

KST’s primary challenge is the intricate modernisation of the expansive Post Office branch network. This intricate task involves updating network and security systems effectively, ensuring uninterrupted operations in the face of technological change. The challenges we face include the complexity of upgrading thousands of diverse sites, accommodating varied security system requirements, and addressing uncertainties surrounding power supply availability.

The Solution

Phase 1: Laying the Foundation

In the first phase of this initiative, KST are diligently focused on laying the groundwork for success. This entails the installation of Cat 5 cables in branch and the termination of devices connected to the old network. As we complete this phase, the baton is passed to Verizon engineers, who orchestrate the network enhancement and establish connections for Voice over Internet Protocol (VoIP) phones and pay stations.

Phase 2: Integration and Validation

In the subsequent phase, which occurs within a window of three to 4 days following the Verizon engineer’s activities, a KST technician returns to the branch. Our mission during this phase involves the commissioning of new signalling devices and the rigorous testing of pre-existing connected security devices connected to the new network. Our approach is rooted in meticulous testing protocols tailored to each device’s specifications. By ensuring the functionality of each existing device, we guarantee that every Post Office branch meets the requisite security and operational standards.


Our partnership with Post Office Ltd in response to the imminent PSTN discontinuation exemplifies our commitment to our clients. By collaborating seamlessly with Verizon and Openreach communication provider, KST effectively addresses challenges and executes a meticulously planned upgrade strategy. Our unique blend of strategic planning, transparent communication, and adaptive solutions ensures that Post Office upholds service excellence, security standards, and operational efficiency across its vast branch network. This initiative underscores our dedication to embracing innovation while safeguarding the continuity of essential services.
