ASSURE X · FAILOVER HARDWARE

When the internet dies,
your business doesn't.

Assure X is the 4G/5G router range behind Telexico's failover deployments. The second your fixed line drops, it cuts over to mobile — card machines keep taking payments, phones keep ringing — and most teams only find out from the alert email.

Assure X LTE6

The dependable workhorse

Cat-6 LTE up to 300Mbps, WiFi 6 AX1800, 4× gigabit + 1× 2.5G Ethernet. Rated −40°C to 70°C with a ~200,000-hour MTBF — built to sit in a comms cabinet for years and just work. Right for most shops, offices and practices.

🚀

Assure X 5G

The performance model

Full 5G (SA/NSA) with LTE Cat-20 fallback — up to 2Gbps — 4×4 MIMO, WiFi 6, the same industrial passive-cooled build. For sites where the backup line carries the whole business at speed: busy hospitality, multi-till retail, larger offices.

🔀

Automatic cutover

Watches your fixed line and switches the moment it fails — then back when service returns. No one touches anything.

📡

Multi-network SIMs

Roams EE, Vodafone, O2 and Three — the strongest signal at your postcode wins, not whichever network you signed with.

🛠️

Zero-touch managed

Firmware, diagnostics and config handled remotely by our UK engineers. You get uptime; we do the tending.

Which model fits depends on your line speed, site size and what has to survive an outage — we specify it as part of the failover design, not as a box off a shelf.

Questions we're asked

Assure X, answered.

Does Assure X switch over automatically?

Yes. The router monitors your fixed line continuously and cuts over to 4G/5G the moment it fails, then returns to the fixed line when service is restored. No manual intervention is needed.

Which networks does the failover use?

We pair Assure X with multi-network SIMs that roam across EE, Vodafone, O2 and Three, connecting to the strongest signal at your site rather than a single network.

Will my card machines and phones keep working in an outage?

That is the point of the design: payments, VoIP calls and cloud apps continue over the mobile connection. We size the model — LTE6 or 5G — to the load your site needs to carry.

Do I need to manage the router?

No. Every Assure X we supply is remotely monitored and managed by Telexico's UK engineers, including firmware and configuration.

Downtime is a choice. Choose against it.
