Comment On the flip side, we have the modern IBM System i (Score 1) 60

On the flip side, we have the modern IBM System i. All software written for the very first System/38 in the 1970s runs unchanged and without recompilation on its followup, the AS/400.

This same software also continues to run on today's IBM System i running the very latest hardware.

A similar situation exists on the System/360 line, which also continues to run on modern hardware today.

Think of all the many rehosting failures that could have been avoided.

And, yes, the battery backup power supply is required and included for the service to work.

Now I do have some corrections for my post. Today, FiOS uses a dedicated VoIP network on its own fiber line for regular phone service and it uses QoS and a very high bandwidth codec so fax machines, modems, etc. work just fine. They can do this with their extremely high bandwidth and low latency. In many areas it's on its own fiber cable and in others it's one of the three modes on multimode fiber. In both cases it's separate from the TV and data networks. Verizon formerly sold VoiceWing which was a true VoIP service and it was unreliable. It was terminated when FiOS was deployed.

Depending on the area, hybrid fiber copper cable companies like Cox and Comcast offer Digital Telephone using either the old DOCSIS or the newer PacketCable. This is a newer technology that adapts traditional digital telephony to use IP networks instead of DOCSIS. It has some practical problems if the underlying IP network does not honor QoS the same way cable telephony already does. It's "sort of" VoIP but works more like traditional telephone system. The advantage is you can use your IP network for your voice traffic. The disadvantage is higher bandwidth and overhead which, like FiOS, can be handled with higher speed networks and dedicated "channels" for the data. In my area, Cox doesn't use IP yet, but FiOS always has. Comcast depends on the area.

In conclusion, the FiOS, Comcast, and Cox solutions all work even when the internet is not working. They all need power and a battery and fully support 911 and all traditional calling features. The underlying transport may be be ViOP, PacketCable over IP, or straight digital telephony over DOCSIS.

And, for that matter, Verizon FiOS telephone service is a very similar concept, except it's sent over a dedicated fiber optic mode (for multi-mode fiber service areas) or over a dedicated fiber optic line (for single-mode fiber service areas). It likewise doesn't use VoIP. Like cable telephony, FiOS telephone service also works perfectly with security systems, fax, etc.

The telephone land line you get from traditional cable companies like Cox and Comcast *is not* VoIP. It is digital telephony over dedicated cable TV channels. This is similar to how cable modems move data over multiple cable TV channels.

So, unless you specifically subscribed to VoIP service, you are using digital telephony, and that's not internet.

The land line still requires power and a backup battery at your premises, but it does not use the internet, and it works *perfectly* with security systems, fax machines, TTY for the deaf, and just about everything else that uses copper phone lines.

Umm, what? Turn your head. And position your mirrors so you have to lean your head to see the side of your car.

Traffic is never so dense you can't force yourself in if you just turn your head to look.

I drive a truck with limited visibility in heavy Washington DC and New York City traffic. I don't understand how people have so much trouble turning their heads.
