Do you have any idea how they will go about clearing these buildings? For example the exchange where I grew up will likely be flattened. The exchange where I live now is not a hideous industrial building and could in theory be converted. No signs yet of any digging to provide fibre to our poles, so it could be a ten year wait. Bob — lots of these on roadworks. I am sure as over half of the building has already been sold off, to total clear it must be a high priority.
I was based at Upper Warlingham exchange for 16 years. Hi Rasb77, would really like to hear your insight on working at this exchange. Could you drop me an email so I can send over a few questions please? Do BT own these sites? Many of these sites could be worth a pretty penny and will surely be wanted by developers. Not any more. Most of the property estate was sold in to pay off debt and leased back over 30yrs. Telephone exchanges, supply and support numerous services, and now other ISP equipment, I suggest it will be a very big task to clear them.
Although a lot of Analogue Private Circuits were converted to Digital between customer sites, because so many customer sites did not have an AC mains supply for the ANTU, they were provide Digital to the serving exchange, then converted to Analogue to the customers site, many with analogue amplifier in the serving exchange, have these been replaced. If you look at the skyline of most exchanges there are microwave links, cell sites and other aerial, etc, also the parts of the core network go through them, especially in rural areas.
How things have changed. What a life! With regards to FTTP, am I right in saying that the exchanges house some active equipment like the fibre handover node? How would the physical cabling work if the exchanges are removed? Would an exchange building be replaced with another type of street cabinet to house the active components? Any headends will need to be relocated and the fibres diverted.
Not an insurmountable task given previous exchange site closures. Exchanges are also a safe deposit box in a bank for everyone with kit and circuits housing their traffic and data. Security will be a big issue. Imagine if you can open up a mini exchange at the end of a street and the clever boys interrupt and hack.
My local exchange, Primrose Hill, which is actually in one of the nicer parts of St. It is in a conservation area so there would be pressure to keep the existing building frontage pleasant solid brick built in keeping with rest of street and not extend it. BT currently has no money to undertake such a massive project, the exchanges they have already closed far exceeded the budget to do so and the risk was crazy. Legacy systems such as red care alarms, megastream and kilostream which are still in service not to mention the MoD services will all need shifting.
Oh and remember most of the mobile networks, emergency services and coastal systems back off to BT services so any roll out of 5G could be impacted. I looked at this almost 20 years ago so i suspect this is more a statement than a real objective, BT would be better off investing in the core network.
Has anyone managed to get into the Consultation document to find out out which other exchanges are facing closure? Would someone kindly help me understand if the list provided exchanges in the published article confirms explicitly that those sites will be retired, closed and fully exited. Been to well over half of those exchanges working for Monterey and Mitie.
As previously stated a lot of exchanges are in a poor state of repair. Shame I miss going around London and the home counties doing a 12 hour night shifts chasing router and cable thefts lol.

Speed: 38Mbps Unlimited. This is especially true if the exchange hosts equipment from rival ISPs, or if it provides leased lines.
Openreach itself predicts that by , the number of copper broadband customers being served by the 4, exchanges will fall to just 1 million. According to ISPreview.
This closure rate will then reportedly speed up until the other 4, have been closed, which is slated for the early years of the s. Is Chorus investing in fibre instead of maintaining copper? How do I log a fault? Why is my broadband a lot slower than usual? Why does the Chorus site display different outage events to my broadband or phone provider? Our network in a nutshell.
