The problem

Our ISP companion wanted emigrate 10,000 money machines away from fixed-line broadband earlier than the PSTN switch-off, with none downtime.

Working with a number of the UK’s largest banks, our companion couldn’t renew their ADSL contracts, for the reason that minimal length would preserve them caught on the PSTN up till the switch-off, at which level they’d lose service.

And since BT’s substitute service SoGEA makes use of the identical previous copper traces because the PSTN, it turns into much less and fewer efficient the additional an endpoint is from the phone trade, which might put rural money factors in danger.

Upgrading to fibre would have meant ready months or years for engineers to dig up roads, paying a premium all of the whereas.

They have been at a loss. None of their fixed-line choices would lower it. 

The answer

Cellular L2TP was the reply. No want to remain caught on fixed-line connectivity whenever you’ve acquired clever cellular knowledge.

We constructed a cellular L2TP product for ISPs, letting them supply clever cellular knowledge and static IPs on prime of their fixed-line companies with out altering gear or giving up management of their community.

Then we arrange an unsteered 4G Multi-network service for the money machines, preserving the identical IP vary that our companion was at the moment utilizing.

After that, migrating the companies was so simple as rerouting visitors. All with no connectivity blips or downtime: folks may use the banks’ money machines all through the method with no bother.

And our companion was capable of finish their PSTN service on their phrases, quite than have the rug ripped out from beneath them by the switch-off.

The end result

No downtime for the money machines or trouble for our companion to arrange new connectivity; only a essential service saved on-line, a contented buyer, and a projected TCV of £2.9m for our companion.

Plus, the money factors at the moment are totally future-proofed: with a cellular income stream, our companion is able to onboard 5G as quickly because it’s obtainable. And in the event that they need to swap to fibre someday, the cellular service will seamlessly transition into on-demand 4G backup.
