TWC/ Spectrum has a 4 line EMTA modem... BUT, IT IS NOT UL APPROVED FOR FIRE ALARM USEAGE. Please call your fire alarm company, they may be able to use a cell modeminterface on it.
The issue is that line supervision measures the 48 vdc "battery " on the line to cause an alarm "trouble" local alarm if the line fails and "battery" is lost.
The TWC EMTA modems continuously supply "battery" even though the coax may be disconnected or power is lost on line amps. Hence it fails UL fire alarm requirements.
Same with intrusion alarms...
However, AT&T should be able to install 2 RJ 31x, used to be rj41 x jacks for the alarm that break off any internal phones if there's an alarm, it tries one line first, put the elevator phone on the second line.
Please contact your alarm company as they will be aware of your exact state& local fire codes.
No one here or at TWC/ Spectrum has that answer.
I know that in Ohio, you can't soley use EMTA cable service, Have had 3 customers have to use a AT&T copper pstn line for the fire and intrusion alarms. That was even with 8 hour run time UPS on the EMTA modem... Uverse with the 8hr UPS might be OK, provided that line supervision actually works, again contact your alarm company, they have dealt with this before.. many times.
EMTA's are supposed to handle BELL pulse dial timing , But if it's an old phone and the dial is sticky, it will fail. You will also have a REN issue with more than 2 mechanical bell phones, you can't exceed a 1.0 REN, they will hose up dialing, many later, dial sets like WE 500's disconnect the bell when you go off hook, but they can't disconnect on hook phones.
Windstream is the competition and is throwing up roadblocks...
If they won't release the number, there's nothing TWC can do about obtaining it, you need to file with the FCC if that's the case.
Would also be nice if they'd allow ADSL competition in (but won't because all their spare pairs are bad) or offer something faster than 3 or 6 meg service....
TWC/Spectrum only provides support to the modem so getting them to fix your existing wiring won't happen. Have you tried calling Verizon/Frontier? I'm sure that you probably won't get anywhere with them since you are not their customer. AV tech is an audio/visual tech. You can probably find someone local via Angie's List or other similar service.
You are correct, if you cancel first, the number can be lost. You want to contact the new provider and you will need to prove you own the number, usually with a copy of a bill. You start the process and the new provider will contact us to initiate the port. Once the port is complete, you can contact our billing team or visit a TWC store to ensure the phone charges are off the account. Please let us know if there are any additional questions.

Make sure your internet modem, the 6190, is on the splitters -3.5 port and not the -7 ports.
Leave the twc modem on a -7 and cable box a -7 as well.
If splitters a -5 -5 -5, doesn't matter, all ports are equal
To disconnect the modem completely, either put a 75 ohm terminator on the empty port or replace the 3 way with a 2 way splitter.
Well, just wanted to update here:
TWC shut off my modem on purpose when I activated the new MAC without telling me, because it was very old and outdated. The tech came to my house and gave me a brand new one and everything was working again. He said they sometimes do that so we are forced to call a person to the house to give us a new one. Just stange that nobody I spoke to on the phone saw that the person did that.
If you text the landline it will go to the Phone 2 Go app you can install on your Android/iOS device. I believe you may have to install the app and get it going first before it works, but it does work.
