As the only non-techie 'superuser' here, I must admit that in recent weeks the increasing use of technical jargon (esp re changes from FTTC to FTTP) has made it significantly more difficult to understand the technical-type conversations without looking up many of the terms each time they appeared.
So I figured a post/thread about what some of them mean, or stand for, might be useful to anyone else here without a technical background. I've just looked up the basic ones I've encountered - hopefully other people here might be able to add to the list in due course, or expand/amend anything that's not clear.
ADSL – "ADSL stands for asymmetric digital subscriber line, also known as standard broadband. It's a type of broadband that provides an internet connection through the same line as your home phone. It's the most basic and commonly available type of connection.” - https://www.moneysupermarket.com/broadband/adsl/
Attenuation - "Attenuation is a general term that refers to any reduction in the strength of a signal. Attenuation occurs with any type of signal, whether digital or analog. Sometimes called loss, attenuation is a natural consequence of signal transmission over long distances." - https://www.techtarget.com/searchnetworking/definition/attenuation
BTOR – (BT) Openreach – "When it comes to broadband (as well as TV and phone packages), there's the network that carries the data and then there's the broadband and TV bundles that you order for your home. We supply network services to more than 650 service providers, for example Sky, BT, Vodafone, and TalkTalk, who use them to bring broadband packages to you." - https://www.openreach.com/
CPU – "The CPU, Central Processing Unit (or simply processor) is the main chip in a computer responsible for carrying out all tasks. It's responsible for telling all the other components in a computer what to do, according to the instructions it is given by the programs (software) running on that computer." - https://www.trustedreviews.com/explainer/what-is-a-cpu-2950255
DHCP – "The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture." - https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol

OLT – "An OLT (optical line terminal), also known as optical line termination, acts as the endpoint hardware device in a passive optical network. The OLT contains a central processing unit (CPU), passive optical network cards, a gateway router (GWR) and a voice gateway (VGW) uplink cards." - https://www.fiberopticshare.com/basic-knowledge-optical-line-terminal-olt.html
ONT - Optical Network Terminal – "ONT is an interface between the Internet Service Provider (ISP) and the end user of fiber Internet. It's an integral part of the fiber optic internet system because it converts optical signals into information your computing devices can digest. In other words, it works as a modem if you get your broadband Internet through Fiber to the Premises (FTTP)." - https://www.stl.tech/blog/a-quick-guide-to-ont-optical-network-terminal/
OR - Openreach – "When it comes to broadband (as well as TV and phone packages), there's the network that carries the data and then there's the broadband and TV bundles that you order for your home. We supply network services to more than 650 service providers, for example Sky, BT, Vodafone, and TalkTalk, who use them to bring broadband packages to you." - https://www.openreach.com/
PON – Passive Optical Networking – "Passive optical networking (PON), like active optical networking, uses fiber optic cabling to provide Ethernet connectivity from a main data source to endpoints." - https://www.cisco.com/c/en/us/products/switches/what-is-passive-optical-networking.html
PSTN – "Landline phone calls have traditionally been delivered over the old telephone network - this is known as the Public Switched Telephone Network (PSTN).

Nice one, @Penny . Although I think the comment at the end of the ADSL description is rather out-of-date/inaccurate - I would suspect there is only a very small percentage of users still on pure ADSL.
Thanks for the post. 👍

As John says, a big Thank You! Being old-fashioned I have printed your post on old-fashioned paper to help understand these increaslngly technical posts, a long way since we started with 2MB on Toucan, tune-up tips and tweaks, and re-running my phone line away from the mains supply which caused interference.
I'm relieved to read the explanation of DSLAM, which had me worried. The only SLAM I experienced came courtesy TalkTalk who caused us two months' downtime of both phone and BB ...

... yeah. We've maybe already passed the tipping point between mostly-adsl and mostly-fibre.
The words used were a quote from the linked article, btw.
Hopefully the technical content of that article (and all the others linked on the first post) will remain valid even if the passage of years renders it all, eventually, a snapshot of the past.
For now it's just a question (for me, anyway) of just trying to *understand* the rather technical details of how the telecomms world is rapidly changing around us.
Interesting times we live in.

Fair enough, @Penny - but do you know anyone still on ADSL? 😉

My old Boss, who lives just south of the Houses of Parliament, can only use ADSL as the local council won't allow any non essential roadworks or additional pavement furniture.................

Recent acronyms that have appeared: DMARC, DKIM, SPF, STUN, ALG, DECT, HDSP, ATA, SIP
All terms I've come across recently and resorted to Wikipedia for explanations.
