Prevent Business Internet Outages: Stay Online When the Line Fails

At the centre is a multi-WAN router with your main line and at least one second, independent path attached: mobile from a different network and, where needed, Starlink. The router continuously checks that each line really carries data and switches over when a fault occurs. With SpeedFusion, traffic additionally runs through a counterpart in the Ascend data center, the Ascend Hub. It keeps calls, VPN tunnels and video conferences open while the router changes lines. Your staff will not notice the internet outage.

A business internet outage rarely has a spectacular cause. A digger hits the cable by the road, the provider has a network fault, the modem gives up after years, a planned maintenance runs longer than announced. None of these causes depends on how fast or expensive your connection is. A fibre connection also runs in the same duct as your neighbours' lines and through the same central office.

That is why a second line only helps if it takes a different path. A second DSL line from the same provider shares cable, equipment and faults with the first. Mobile reaches the building over the air and through a different network, Starlink via satellite. This independence is what turns two connections into a resilient one.

The multi-WAN router checks each line not just for link, but for real reachability on the internet. Only when a check fails does it move traffic to the other path. Once the main line is back, it switches back automatically so the second line is free again.

For most sites, 5G or LTE is the simplest second line. An outdoor antenna on the building gives stable reception even where a smartphone in the office shows a single bar. What matters is the network: we recommend the Ascend data plan as a multi-network SIM. In Germany it registers automatically with Vodafone, O2 or Telekom, either on best network or with a fixed network choice, so the backup SIM does not sit on the same network as your fixed-line provider. The plan is prepaid, stops at 0 euros, can be cancelled monthly, applies at the same price across the EU and has its internet breakout in Frankfurt with a German IP address.

Where no mobile network is reliable, for example in an industrial estate on the edge of town or a hall with a metal roof, we use Starlink as a second or third path. The router treats the satellite link like any other WAN line and bonds it with mobile and fixed line.

Both paths come together on the router. Peplink routers such as the B One 5G or the Balance 20X include the mobile modem and also offer Gigabit WAN ports for the fixed line. Teltonika routers such as the RUTX50 work with two SIM cards and switch to the second SIM automatically on a network fault. For hot failover and bonding, the Peplink router connects via SpeedFusion to the Ascend Hub in our data center, which holds the sessions.

Retail and hospitality. The card terminal, the till and the inventory system all depend on the line. If it fails, only cash is left. With hot failover the terminal keeps booking, and the delivery note goes out.

Medical practices, pharmacies and law firms. The electronic patient record, prescriptions and appointment booking run online. A practice without internet sends patients home. A second line over mobile costs a fraction of that.

Branches and sites. If you connect several sites to headquarters by VPN, every site needs a second path. The bonded tunnel to the Ascend Hub keeps the site network up even when a digger arrives at one branch.

Production and logistics. Machine data, warehouse scanners and links to freight portals tolerate no pause. Bonding is worthwhile here, so that even in normal operation there is enough bandwidth for remote maintenance and cloud applications.

Home office and remote sites. A compact router with an LTE modem secures the home workplace or the construction-site office and keeps the VPN access to the company open.

Since 2010 Ascend has planned and operated resilient connectivity for businesses, from the single practice to the branch chain, based in Nuremberg with assignments across Germany. We are a partner of Peplink and Teltonika and supply the routers from our own shop, pre-configured with your lines, the Ascend SIM and the SpeedFusion profile to the Ascend Hub.

On site our technicians mount the outdoor antenna, router and, if needed, the Starlink antenna, check reception and test the failover case with you: we pull the main line, and you see that POS, phone and video call keep running.

After that comes the part most providers leave out: 24×7 support and, on request, round-the-clock monitoring of your connection. If the main line fails, we see it in monitoring and get in touch while your business runs over the second line. You get a connection that works, and a contact who is reachable around the clock when it does not.
