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.
Call Blocker Plus for the win.
Or was that too simplified?
Call Blocker Plus has the added functionality of blocking calls from callers who are spoofing/faking their caller ID, which is illegal to fake your caller ID, but many telemarketers do so.
When you see "Out of Area" it could also be a provider glitch. Meaning that the person calling you didn't get their phone #'s caller ID (which is called a CNAM) added into the database correctly. So it's not 100% a telemarketer, but most likely it is a telemarketer.
I'd also recommend if trying to screen out calls that you get by opting-in for Nomorobo.com
It will allow legit things like pharmacy pickup and school closing notifications to go though, but block known telemarketers that were reported to donotcall.gov.
Which reminds me, also add your number to donotcall.gov; that way you can file a complaint on the first telemarketer that calls you, they get fined for having called you when you're on the list. The longer you're on the do-not-call list, the better. The more telemarkers you file completed complaint tickets on, the more they'll avoid your number like the plague. Nomorobo takes this a step further, but this was where it all started. Your tax dollars fund this so... why not?
They're free services, all three I just mentioned. But YOU the customer must opt-in. Legally we can't just opt you in, although in many cases I wish I could just do that for customers.
You can control turning on (opt-in) on the Nomorobo and Call Blocker Plus of these yourself though the "TWC ID" MyServices portal here:
If you're having issues with logging into the MyServices portal, then call us and ask to speak to the "Tier3 Department" which is specifically trained and has the access permissions necessary to help customers with that. Please have a bill statement handy, because they'll need to authenticate you by your 4-digit customer code on your bill.
As a general note, if one must absolutely must get the real # of a phone # calling you, it's going to have to go to a subpoena (approved by a judge) because in the USA call identity is confidential information. No ISP may release it unless to comply with law enforcement investigation. I've only dealt with that like twice in my entire time working for the company, and in both cases it was potentially-life-threatening death-threats & harassment being made. When you start illegally using a phone to threaten somebody all of your confidentiality protections by your service provider blows out the window. Same can happen in cases of abuse quarantines on internet service.
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....
