I believe when talking about naval ships, commissioning is when they enter active service, so construction probably began early 90s, maybe even late 80s, and probably a few years of designing, bidding, etc before that. And of course there were probably all of the usual idiot politicians, bean counters, stubborn assholes, sales people, etc. involved who pushed for older tech. Maybe because everything else they had worked on the old disks, maybe they were skeptical of the new tech not being robust or tested enough or wouldn’t catch on, maybe it was just cheaper, etc.

I’m willing to bet that they somehow locked themselves into using 8 inch disks in the early to mid 80s if not earlier, when the 5¼ discs were still new-ish and the 3½ were brand-new or not even available yet.

So I don’t have any specific insight to what’s available in the Netherlands

But I kind of feel like maybe you’re explaining what you’re looking for poorly

First some terminology

SIM and e-SIM are basically how your cellular service provider knows that your phone is connected to your account. The phone that has either that physical SIM card inserted, or that e-SIM data gets the calls, texts, data, etc. that are supposed to go to you. Take the SIM card out or change the e-SIM, and that phone no longer gets those calls, texts, and data. Put that same sim or e sim on another phone and it starts getting all those calls texts and data.

VoIP is Voice over Internet protocol, basically sending a phone call over the Internet instead of over phone lines. This might be from a computer, or from something that looks like a landline phone (or maybe even is a regular landline phone with some sort of adapter) or from a cell phone with a VoIP app installed. To use it from a cell phone you’d need to have either a WiFi connection, or a cellular data connection, and to have that cellular data connection you need to have either a sim or e-sim.

I don’t think there’s any VoIP provider that’s set up to just use your phone’s dialer and text app to directly handle calls and texts (though I could be wrong on that, I don’t try to keep up with all of the different types of phone services out there) everything would have to go through their app. If you want to do that, and you’re either ok having no cellular data and all of your calls, texts, and data use would have to go over WiFi, or if you keep paying for a cell plan (and the associated SIM/e-SIM) maybe either just a data plan with no talk/text, or a regular plan and you just don’t use the talk and text parts, then you just need to track down a VoIP provider, sign up for an account, and install their app on your phone.

If you want to transfer your actual phone number from your cell phone to a VoIP account, either to use on your cell phone through that VoIP app, from a computer, or from one of those landline VoIP devices, I don’t think that’s really a thing. If you just want calls to your cell to go to your VoIP phone number as well you’re looking for call forwarding.

You might also be getting tripped up with things like WiFi calling, VoLTE/VoNR (marked by some carriers with terms like “HD Voice”) which are things that are all going to be dependent on a regular cell carrier, not a specific VoIP company, and may depend a bit on their network infrastructure and what features your partic6 phone does or doesn’t support.

Yeah, didn’t mean to imply that you were, just wanted to expand on options for deaf people that are already out there, and point out some of the relative strengths and weaknesses they have compared to text-to-911

This absolutely can be a useful tool for deaf people or others with hearing/speech difficulties.

However, there are already several ways for deaf people to contact 911 without text-to-911

I work in 911 dispatch, probably the most common way I’ve gotten calls from deaf people is through a video really interpreter. The caller is basically on a video call with an interpreter and they relay what’s being said to us. There’s very little delay in communication like there can be when you’re typing back and forth, and usually it works pretty well. There are some situations where it has its issues, if the caller is somewhere dark it can be hard for the interpreter to see what they’re signing, if they don’t have a video-capable device they of course can’t use it at all, and a lot of our deaf callers come from a behavioral health group home place in our county, and some of those callers have a tendency to just kind of walk off-street in the middle of the call, though it’s still kind of useful because the interpreter can at least try to describe what they’re seeing and hearing in the background if the caller didn’t hang up.

Also all 911 centers (in the US at least, I assume it’s probably the same elsewhere in the world) are required to take TTY/TTD calls. The classic example of these is the caller has a device that kind of looks like a typewriter with a little screen and a speaker and microphone they place a phone handset on. They type out their message,the device turns it into a bunch of beeping noises that go out over the phone line like a regular voice call, and the person on the other end’s TTY device (in our case it’s built into our computer phone system) decodes the beeps back into text. Most, if not all cell phones these days also have TTY built into them in the accessibility settings somewhere. There’s some grammar peculiarities because it doesn’t really include punctuation, and some tty users will use ASL gloss, which is a written form of ASL (ASL isn’t totally 1:1 with English, and if you don’t know what you’re looking at ASL gloss reads kind of like that bit from The Office “why waste time say lot word when few word do trick.”) It also allows for hearing or voice carryover, where the caller is able to hear but not speak or vice-versa, so you only need to use TTY for half the conversation and can communicate verbally for the other half. The 2 biggest drawback is that we hear all of these TTY beeps in our headset, and they get pretty annoying really quick, small price to pay though, and generally only one party can be typing at a time, so you have to wait for them to finish before you can reply.

I will say that, at least in my area, TTY is vanishingly rare. In the 6 years I’ve been here, I’d be amazed if we’ve gotten 3 calls from an actual deaf person using TTY, although we did have one mental health patient who used it on his cell phone and used it to just ramble nonsense at us. He had no hearing or speech difficulties, sometimes we were able to get him to talk to us

In either case, if you call from a landline, we get your address just like a regular phone call, with tty from a cell we also get your cellular location like a regular call. Video relay calls from cell phones can get a little funny location wise because of how the call needs to be routed, often it works out that we get a home address they have on file and not their actual current location. With texts the location data often isn’t very good (although we’re implementing some new technologies at my center that improve on it a bit, though it’s still not as reliable as a voice call in some ways)

I posted another comment/rant in this thread with some of my gripes about how people use text to 911 if you haven’t already seen that, and I do want to reiterate that it is a really good option to have available, we can always use more tools in our toolbox, and it can definitely be useful in some circumstances, but it does tend to get misused in some frustrating ways for us.

I work in 911 dispatch, there is an audible groan whenever anyone here gets a text to 911

Don’t get me wrong, I’m glad that it’s a tool that’s available, there are certain cases where it can be really useful, domestic abuse situations where you’re unable to make a voice call because you’re abuser is in the room or car with you, an active shooter situation where you’re hiding and don’t want to give away your location, people with hearing or speech issues, etc.

That’s almost never what it gets used for.

Most of the time it’s someone calling in some non-emergency. I suspect in their minds it’s probably quicker and more convenient for us to get a text, but it really isn’t. We’re not multitasking and taking other calls at the same time we’re on the text, when we’re on the text, that is what we’re doing, same as if we were on a regular 911 call. And that first text usually is missing some crucial information about what is going on, and it takes a whole lot longer to go back and for asking questions and waiting for an answer by text than if you just made a phone call, if they even reply at all to answer my questions, very often they put their phone in their pocket and never look at it again for the rest of the night. We can’t even call them back because we don’t know if it’s safe for them to speak on the phone, we just have to sit there for 5 minutes waiting for a reply that isn’t coming before we can disconnect.

I’ve also definitely had at least one instance where the caller was definitely texting while driving, and not for anything remotely urgent enough that they couldn’t have found somewhere safe to pull over first.

Agency policies will vary on how texts to be handled, I can only really speak for where I work.

Most calls, even a lot of actual actual emergencies, if my caller is cooperative and knows where they are, and the situation isn’t actively evolving while I’m on the phone, I can handle in about 2 minutes or less, sometimes I can even get it down to less than a minute. I’m going to easily spend twice that on most text conversations, and often I’m going to be tied up on it significantly longer.

Technology also varies a bit from one place to another, but we also don’t get the same kind of location info with a text like we do on a regular phonecall (and even on a call our location data may not always be super accurate or useful) we did recently get some of our systems updated, and we get more information than we did before, but it’s still less reliable than on a phone call.

And we also can’t transfer a text like we can with a voice call, so if you’re texting regarding something going on at your grandma’s house in another state (we get calls like that all the time, where someone tells a friend or relative about something going on, but can’t or won’t call 911 themselves) we have to either A convince you to take a voice call so we can transfer you, or B make a call to them while still texting you, and play middle man relaying questions and answers between you and the other dispatcher, so you’re tying up dispatchers in 2 jurisdictions on your call (it used to be that we weren’t able to make an outgoing call while we were on a text, so we’d have to have 2 dispatchers at our center tied up on these texts, one to message back and forth with you, and another to relay the info to the correct agency by phone. We’re a pretty well-funded county, so I’m sure there’s a lot of dispatch centers still out there where that’s still the case)

I already occasionally get people trying to send us pictures and links with no explanation (pro-tip, we can’t see your pictures or open your links with our current tech, and even if we could opening links would probably be a no-no from a cyber security standpoint)

If at all possible, please just make a voice call, it will be quicker. If you genuinely cannot make a voice call, at least make sure your first text contains the correct location (address, municipality, nearest cross street, apartment number or name of the business if applicable should cover your bases pretty well) and a good description of what is going on. Then please keep your phone with you and try to answer any follow up texts we send you quickly and succinctly.

And again, don’t get me wrong, it really can be an amazing tool when it’s needed, but it’s a massive pain in the ass for us when people use it when it’s not necessary and usually makes just about every part of our job harder and slower, which means slower responses to your emergency.

It’s going to depend a bit on the agency, different places use different systems and have different policies available to them.

Where I work, we used to have Google maps integrated into our CAD (Computer Added Dispatch) so it would sync to the built in map in our CAD. I believe it was some sort of 3rd party plugin, not something the cad developers officially supported, so it was always kind of slow and buggy, and some update that happened a couple years ago totally broke it so we no longer have that.

We do use Google maps through a web browser pretty frequently. We have most of the businesses, parks, schools, cemeteries, etc. loaded into our CAD, but they’re not labeled on the map, and sometimes being able to ask “can you see the Starbucks from where you are” can be kind of useful, and the satellite view is really useful for our more rural areas where they may not be many obvious landmarks and it’s all fields and trees.

Some departments have some stricter internet usage policies and such and may not be able to use Google maps.

Street view has its uses, mostly for narrowing down the exact address. Most of the time it’s not super necessary, we can send police out to the nearest intersection if needed, and they can find “the big house with a red door” or whatever themselves, but if we can narrow down the exact address, sometimes we may have important caution note attached to the address, and of course it can sometimes shave a few minutes off of our response time if our responders don’t have to go hunting for the right house.

One of the times street view came in particular handy for me was one time I had a 3rd party calling about something for a friend. They weren’t sure of the exact address, but they knew the road and some nearby landmarks that had it narrowed down to about 2 or 3 blocks. The caller kept saying that there was a “big yellow walkman” on the front porch, and was too worked up to really elaborate on what she meant by that. I turned to street view and just kind of went down the block looking at porches until I found one that had one of those fluorescent yellow/green “children at play” signs people put in the street that are shaped like a kid walking and it clicked that that was what she meant.

It’s not just youth, it’s people across the entire population that have issues reading maps.

I work in 911 dispatch, obviously a big part of the job is all about location. We spend a lot of our shift looking at maps on our screen trying to figure out where people are so we can send them help.

In training for a couple days, they busted out paper maps of our county and had us locate different intersections, landmarks, etc. our class skewed a bit younger, mostly millennials at the time (this was about 6 years ago) but also some Gen x and boomers. I’d say only about 3 out of the 12 of us were really proficient at all at reading a map.theru wasn’t any particular age bias, really what it seemed to come down to is “who was in boy scouts”

And it’s not a new thing, a lot of people have had a hard time with maps probably since maps were invented. It takes certain kinds of spatial reasoning skills that some people just struggle with. My boomer mom could never read a map, a lot of my grade school years were the days before GPS and half of my class always struggled with it when it came up in history/geography/social studies, it’s been used as a joke in movies for decades. It’s probably gotten somewhat worse since people don’t use paper maps as much anymore, but there’s also a “use it or lose it” aspect, I noticed that my own map and compass skills have degraded a little recently while hiking a new trail with a paper map, there’s probably a few older people who used to be pretty proficient at reading a map but would have a hard time with it since they haven’t had to in over a decade.
