Intro / Overview
Ocean Telecom partnered with CSL to deliver a reliable and future-proof communication solution for a large UK organisation operating approximately 250 lifts nationwide. With the 2027 PSTN switch-off approaching, the customer required a cost-effective way to upgrade their lift alarm systems without disruption or major infrastructure changes.
Background & Challenge
Ocean Telecom’s customer relied on PSTN-connected lift emergency alarms, which faced becoming non-compliant and potentially unsafe once PSTN services are withdrawn in 2027. The challenge was to replace these connections quickly and reliably, without the cost and disruption of rewiring or replacing existing lift systems.
An additional consideration was installation scheduling. Lift alarm upgrades needed to align with routine maintenance visits carried out by a third-party lift servicing company, meaning the solution had to be simple to deploy without requiring additional site visits.
The Solution
To address these challenges, Ocean Telecom deployed CSL’s VoiceLink solution. VoiceLink connects lift alarms directly to mobile networks, removing the reliance on PSTN lines and ensuring compliance with new all-IP connectivity standards.
The plug-and-play design allowed VoiceLink units to be installed during standard lift maintenance visits, avoiding costly rewiring and minimising operational disruption. Ocean Telecom activated the units in advance, providing a one-month window for installation to align seamlessly with the existing maintenance schedule.
A key benefit of the solution is CSL’s web-based management portal, giving Ocean Telecom and their customer real-time visibility of all deployed devices. This enables monitoring of connection status, power levels, battery health, and alerts, while allowing settings such as outgoing numbers and test calls to be customised.
