Thanks to an aging workforce, the telco industry is dealing with the significant challenge of maintenance and operation of legacy Synchronous Digital Hierarchy (SDH) networks. SDH networks, introduced in the 1990s were revolutionary, providing exceptional traffic path availability through advanced management, reporting, and protection mechanisms.
Introduced in the 1990s, “self-healing” SDH networks once represented a revolutionary step forward in network architecture, synchronisation, and protection. With networks moving to higher bandwidth, lower cost ethernet circuits, this once industry standard technology is being replaced, but this cannot be achieved overnight, and a host of risks emerge if SDH networks are not adequately maintained or decommissioned with the proper care. Understanding these challenges is crucial for network operators.

When we talk about convergence, it usually involves us integrating two technologies together to do something technologically new or better than before. But too often we forget to think about convergence of cyber security technology with the wider physical world around us.
We read a lot about what the ‘Internet of Things’ (IOT) can bring to modern day living – that is to say, the array of devices we can connect to the net to deliver us the services we need. Not simply internet shopping, but a whole plethora of services that can be delivered to us at home, such as health services – booking appointments with GPs, interacting with our kids’ schools in their learning programmes, driverless cars and home automation – even our bins may eventually be linked to the ‘smart cities’ in which we live to tell the council when to empty them.
What comes next? It’s the 60-million dollar question that most organisations in many sectors are asking themselves. Recent months have shown just how critical the UK’s digital inclusion plan is. With broadband connectivity in our homes taking centre stage, we’ve firmly relied upon it to keep economic activity alive through a time when so many have had to close physical doors.
The overnight need for a nation to work from home has put many technical issues under the spotlight, but none more so than the immediate and far-reaching test of the UK’s broadband capabilities. It’s not just the tasks associated with working from home, like teleconferences over the various internet-based applications such as Microsoft Teams or Zoom, but also the extra activity created by having school aged children at home who want to use broadband-hungry gaming apps, as well as make use of new streaming services like Disney+.
So much of what we do on a daily basis is about the human element of our role – how we interact with colleagues, customers and suppliers. Operating in an enormously technical world where we spend days talking about fibre infrastructure, data and IT security, it’s easy to think that when things go wrong as they sometimes do, the problem is the technology. But experience in service delivery tells us that’s often not the case – it’s the people-driven processes behind the job at hand.
According to research conducted in April 2020 for INCA by intelligence company, Point Topic it suggests that the UK’s independent network operators passed 1.2 million homes with fixed superfast or ultrafast broadband.
