What legacy telecom equipment from the early 2000s still causes problems in EU networks?

I'm an engineering student looking into how FPGA-based emulation could help extend the life of older telecom hardware still in use across European networks. Before diving into development, I want to gather insights from professionals in the field about the challenges they face daily. Specifically, I'm interested in which legacy equipment is still common in EU networks but difficult to source parts for. Is it typically a single chip that fails, or does the entire board become useless? Also, are operators inclined to repair such equipment or would they rather replace it altogether? Any feedback, even critical, would be super helpful.

Printers and fax machines are often the most problematic. They're still in use in many places, but getting replacement parts can be a hassle. These older models were never designed with longevity in mind, so they break down frequently.

This post seems to be misguided. Asking for details about critical systems that can't be patched isn't wise. The real issue isn't about the equipment; it's often management reluctance to invest in upgrades, leading to patchy technology and increased maintenance headaches.

You might get better responses in a telecom-focused community. I've seen some operators struggle with maintenance due to a reluctance to invest in newer technology; they often hold onto existing systems longer than they should.

If a piece has chips, it's no longer considered ‘legacy.’ I used to work for German railways with infrastructure that was still mechanical as of 2018. In terms of legacy equipment, it’s usually tough to find specific parts because companies like Siemens keep these systems running. It's hard to discern between a failed chip and a board failure, and repairs typically mean swapping whole boards instead of individual chips.

In the UK, I still use an old rotary dial telephone from the 1970s, and it works fine with modern routers. It's interesting how some of these older models are more reliable for certain users compared to newer digital devices. Though I also have a fax machine, it’s just gathering dust now since we don’t operate a home business anymore.

TechWander3r: Thanks for the honest feedback! You bring up a good point about how the repair market operates. I know there are smaller companies buying damaged boards for refurbishment but they hit a wall when they need discontinued chips. Would FPGA emulation be a game-changer in scenarios like this? Or do most repair shops opt for board replacements anyway?
