Unless you've tuned your system for it, dial-up modem speeds are functionally equivalent to "no connection at all".

I pulled out a WRT54G the other day and set it to a 56K limit. A netbook running ubuntu(ish) took several days to complete an apt-get update. But when I connected my laptop with 50 browser tabs, the tabs themselves consumed 100% of the bandwidth with background traffic (despite my ad blocker) and no other network services worked at all. Unless you've tuned your system for it, dial-up modem speeds are functionally equ…
It's brutal, even with modern Internet, when people develop apps with the assumption of the Internet connection always having decent latency and bandwidth.

33.6Kbps is not practical for much on the modern Internet in 2026. As mentioned in a sibling comment, Starlink (even in standby mode) would be much better. lite.cnn.com would load in about 10 seconds which is pretty good, but there's not much else like it left anymore.
What's amazing is how great the Internet in the 1990s managed to be despite these limitations. Just like with RAM and disk space, developers back then had to be very mindful of bandwidth - today's devs (and agents) have the luxury of paying much less attention to that.

If you ever want more phone lines than that, you can pick up an old Cisco VG-224 from Ebay for less than half the price of that line simulator, and you get 24 lines. There is a configuration that will let you use it as a standalone unit where all the lines can call each other with custom phone numbers (here's some notes [1]). The main catch is that they have a 50-pin Centronics style connector on them which you will…
This is just another lost art (traditional phones are either dead or are instead IP) that I once learned a fair bit about:
The name varies regionally (I've heard them called Centronics, cinch, and CHAMP; though around here, we call them Amphenols). The Easy Method is the same regardless of name: It centers around a split (aka "50 pair") 66 punch block[1] that is mounted to a wall, or to a wall-like object.
Buy a pre-terminated 25-pair cable with the right connector on at least one end, and punch that down in order[2] on one side of the 66 block. That connects the system to the punch block. Importantly, those wires never get touched again.
Phones (or more precisely, wires for jacks for phones) connect to the other side of the 66 block. Those wires also never get touched again.
The two things (phones, systems) are connected/disconnected with bridge clips that combine the two halves of the block (which only allows 1:1 ordering, but that's often just fine).
Alternatively, a "we fancy!" variation uses single-pair cross-connect wire so that arbitrary phones can quickly be connected to arbitrary system ports -- maybe on completely separate blocks.
After that, plug in the Amphenol. Plug in the phones. Have fun talking to yourself.
(Or, at least: That's an easy way for small stuff. Bigger stuff (hundreds or thousands of pairs) eventually really wants better organization, but punch blocks are still normally the order of the day there, too.)

Jeff mentioned in his video that just loading the front page of CNN would take something like an hour and a half (20+ MB). 33.6Kbps is not practical for much on the modern Internet in 2026.

20+ mb is the weight of all the javascript javascripting, ultimately to arrange and display an html page.
What I would love to have is a few compact dialup-to-wifi bridges so I could wifi-ize 30 year old hardware. Would be neat to read email with an old POP client, or chat over the original AIM software (perhaps patched to use a server on the LAN)
However, to be frank, it'd make more sense to do PPP over null modem with a straight serial connection.
I feel like it would have been more fun to build your own line simulator with a 9 volt battery and some old phone line and just skip the dialtone altogether for a little magic... the $120 black-box telco simulator takes a lot of the fun out. But then again, based on Pi pricing today, the $120 telco simulator goes nicely with a $300 Pi 5.
Line simulators are fun. The ports can call each other and there's no need to set any custom init strings on the modem like you need with the 9 volt trick. For some old devices that's a necessity. You can also use an old VoIP ATA from Linksys/Cisco as a cheap line simulator. Like a fully analog TLS the ports can call each other. They can be a PITA to configure right but they're cheap and work well enough. I've used a…
Just issue ATX0D on one modem and ATA on the other. Bingo bango: One modem thinks it's initiating a call (without concern about the lack of dialtone), and the other thinks it is answering a call.
But yeah, simulators are fun. A person I used to call "boss" used one with a dry pair of copper that ran all the way across town for his internet connection for a couple of years.
(His shop had space that was used by a local dialup ISP for a POP. In exchange for the space and the electricity, his shop got free internet over a T1 in the days before we had DSL or DOCSIS. It was a great trade for both parties and I felt giddy downloading things at work at >1.5 Mbps instead of ~0.0336 Mbps.
In an effort to save some money on a dedicated phone line and ISP bill at home, he ordered a cheap circuit from the phone company that they billed as an "alarm circuit" -- it was about $20 per month.
One modem was his at house behaving mostly-normally along with the simulator, and another was at the shop connected to our all-singing, all-dancing 486DX4 Linux box. It was stable and cheap and somewhat ridiculous.)

There are services which will remove all but the text when browsing and make it greatly lighter. 20+ mb is the weight of all the javascript javascripting, ultimately to arrange and display an html page.

From what I understand of telecom of that era. You want to effectively keep as much of the signal digital as possible. With (ideally) the only "analog" part remaining being the link between the customer modem and the PBX.
The VG224 being (effectively) 24 ATA's in a trenchcoat seems to meet that requirement. Though once installed you'd need to connect it to a PBX such as Asterisk. Then, as I understand it, "trunk" that as a T1 line into something that can digitally handle modem calls such as a Cisco AS5300.
