NETWORK AND TELECOMS
Keeping you connected
The UK is currently undergoing the biggest communications upgrade in a generation. Openreach is retiring the old copper telephone network (PSTN and ISDN) by January 2027, moving the entire country to a faster, more reliable all-digital infrastructure. While this transition marks the end of traditional landlines, it opens the door to far superior connectivity for your business.
WHAT DOES THIS MEAN TO YOU AS A CUSTOMER?
If you are currently using older broadband connections like ADSL or FTTC, or if your office phones plug directly into a traditional wall socket, your services will need to be upgraded to an IP-based alternative before the network is permanently switched off.
You don't have to manage this complex migration alone. Col-Tech Group specialises in transitioning businesses across Lincoln and Lincolnshire to the digital future seamlessly. From implementing crystal-clear VoIP phone systems to installing high-speed leased lines and enterprise-grade networking hardware, we ensure your business stays connected, competitive, and completely uninterrupted.

FREQUENTLY ASKED QUESTIONS
