Fast or safe, but not both

When Verizon called me and offered me a month of DSL service for free, complete with the equipment and even a postage paid return box (since I would inevitably be sending the modem back at the end of the free month), I decided to give it a shot. After all, who wouldn't mind having high-speed access for free for a month?

When the customer service rep was giving me the rundown, she (I think it was a she... looking back, it may have been a "he" with a really high voice) quickly mumbled that "though most residential home alarm systems should work without conflict, if you encounter problems, please call us." I kind of glazed over it, figuring, "OK, that probably means the standard phone filters they include (to allow use of DSL and the phone line at the sametime) work with most major alarm systems."

The start-up kit arrived yesterday. As I started to put the filters on my phones, I noticed (or should I say "re-noticed" since I remember noticing this before) that the alarm system is wired directly into the phone line, rather than through the phone jack on the same wall. I realized there was no way I could put a filter between the alarm system and the phone line. So I called ADT and they confirmed that yes, I would need a technician to come out and put a special filter on. And, oh, by the way sir, that will cost you $97 for the first 30 minutes of the technician's time ("It's not considered 'normal wear and tear'."). I declined setting up an appointment and called Verizon to check on what ADT told me. Tech support confirmed what ADT said and added that simply setting up the DSL modem could cause my alarm system to go wacky, even if I disconnect the modem when I arm the alarm.

So, basically, if I want my "free" month of DSL, I need to shell out $100 for a filter I'll only really use for a month. Why these filters aren't automatically built into alarm systems nowadays, I have no clue.

This guy has some good thoughts on the issue, which apparently is pretty common. And he even came to same conclusion I did last night: I can have fast Internet or the security a home alarm system provides, but not both. At least not cheaply.

Wow. DSL finally comes to Leesburg, otherwise known as The Broadband Ghetto

Hey,
I am now seeing that dsl is not easy. I am having the SAME trouble with ADt, I had been passed from you need to call the alarm place, then back to the dsl provider, then phone company, and etc etc. I was really getting upset. I would get a alarm filter ONLY that I can not find any place that sells them, nor do I know where to go for one. If anyone can tell me of somewhere online OR in a store I would appreciate it. I am really wanting to get this DSL hooked up.
Thanks..

Still no DSL here, about half a mile outside the Vienna town limits. Just lucky I guess! (We could get cable broadband service, but we're paying Cox enough as it is for television.)

I have the DSL filter on my ADT alarm and I am still unable to connect. I think the issue may be that the ADT system is still sending packets to the alarm box even with the filter on or the alarm unplugged. These packets seem to be dropping me off the PPPOE connection and cuasing serious issues. I have the phone comany out and they say everything is wired fine so????

We have the filters available on our web site for the homeowner to install themselves. Installation is a snap– just plug the filter into the alarm panel’s telephone connection (RJ31X-RJ38X). Please email us if you have any questions at support@lufkinsecurity.com

Visit our website for info & pricing on the RJ31x DSL Filter used in alarm systems.

Damn...I'm encountering the same problem you are. I signed up with Verizon Online only to find out later that I need the RJ31X filter for my alarm system. I called Verizon for it and they say that they don't sell it. I called ADT and they want to charge 40 bucks for it. On top of everything, I was surfing the web and some dude said that the filter still don't block/filter out everything because he was still getting dropped. He noticed that DSL worked better for him without the filter and that he has to be inconvinenced, i.e. lose DSL, when ever he turns on the alarm. I think I'm going to pay the extra bucks for cable and say SCREW Verizon!

If you search online you can find a RJ32X DSL inline filter for about $20-$30. All you have to do is unplug the jack from your alarm and put the filter inline.

Question: Regarding DSL & ADT Alarm system. I have an ADT alarm System with the phone line built into the wall. I am wondering can I still run DSL without a filter on the Alarm system? I've seen some posting traffic that says you can, but you cannot "ARM" your alarm. Is this true?

Posted by: Michael Law on March 8, 2004 8:47 AM

I have had DSL for a couple of years. Then a couple of months ago, I got ADT. Things seemed to be going fine, and now things are not so good. I don't know if it is Verizon, the phone line, modem, or ADT. I am looking into getting the RJ31X filter, but that sounds like it won't help.

If anybody solves this problem successfully please post back here.

Posted by: Ken on May 6, 2004 7:15 PM

from looking at the comments the problem may be cause by where the ADT panel is placed in the phone line. Example-if the ADT panel is first inline on the circuit and ADT filter is installed all of the remaining extension in the house will be effected. Per the installation "CD" the computer or DSL modem should not be filtered. Have the ADT panel placed out of the main line and onto its own extension.

Posted by: paul on June 10, 2004 11:15 PM

I have ADT, but the jack that DSL will be connected to is connected directly to the phone box outside. They are all still the same phone number/line? though. Will the ADT still be a problem?

Posted by: Todd on July 28, 2004 8:17 AM

This is like an epidemic! Same story: I've been w/ADT for yrs; subscribed to DSL several mos ago; no problem first 3 mos; evidently the home system sends a monthly signal to the central office to test the system. ADT notified me that the office was not receiving the signal (after several mos using DSL!). ADT told me to contact filter distributor; ADT would install @ $100 for first 30 min. etc. etc. Called Verizon to ask why DSL installer had not asked me if I have an alarm system. Went to Circuit City to buy filter; they never heard of a RJ31X filter; found it on line (there are several websites; just search for RJ31X filter). Good luck; haven't received mine yet, but I hope I can plug it in myself. My alarm is connected to a separate phone jack.

Posted by: sanmonical on August 15, 2004 12:59 PM

Was anyone able to get the RJ31X to work? Is it as easy as they say to install--just plug in? I'm considering signing up for DSL. I am definitely not technically adept.

Posted by: Susan on December 23, 2004 1:53 PM

I found the Excelcius filter at www.HomeSecurityStore.com for $25 shipped to my door. This is the same model my security service was going to sell to me for $45 and install for $75 (same story as decribed by others here).

Has anyone thought about installing a DSL splitter instead of the filter for the alarm system?

Posted by: Travlinsam on May 17, 2005 8:44 AM

The main problem with DSL and security systems, gate access, and a few others. Is simply that they have to have the phone service before any other item in your house. An alarm panel actually seizes the phone line when it goes into alarm. If you ever look, you'll notice it takes four phone wires. Two coming in and two returning. The phone service passes through the alarm panel first so that when it calls the monitoring station it physically disconnects the house phones. That's why the line goes "dead" when you set it off for a few seconds.

The easiest quickest and fastest fix to this problem is very simple. It takes a small bit of technical know how. Go outside your house and at the "demarc" place a splitter. Split the signal so that you assign two phone lines incoming to your home. Line 1 - filtered, Line - 2 unfiltered. I've done this over a hundred times setting up phones and such. I've never used any splitter other than the one's that they provide for free. I just cut off the plug end and hardwired everything. Newer "demarc" blocks even have the RJ11 plugs already there so you can simply plug and play the whole deal. After all that's done, just use the secondary wire pair and change a jack in the house. It's done, you don't have to call the security company, you don't have to pay 50 dollars for a filter (which does the exact same thing) and you know exactly what was done and where so that you can answer all future questions anyone has. Best of all it cost nothing and requires only a flathead screwdriver.

FYI.. the RJ31X block is just a plug that allows you to disconnect or reconnect the alarm panel in case the dialer goes crazy, it restores the "line seizure" that the panel was doing. They're not necessacry just convenient.

Posted by: Derrick Dale on May 20, 2005 2:26 AM

We have ADT, and DSL. The alarm box doesn't have a phone plug whatsoever -- just wires. So I'm trying Derrick Dale's options. In the phone box, it's one of the newer 'demarc' boxes with the RJ11 plug and play. We only have one pair of wires, one wire coming and one going (it's one that is blue and the other is blue with a white stripe). So I'm not sure how to split that.
The other color wires are pairs of orange, green, and brown I believe.
Also what does Derrick Dale mean by: 'After all that's done, just use the secondary wire pair and change a jack in the house.'
Also, for some reason, the splitter is too big for the housing, I can't close it using the plug.
Any ideas?

Posted by: vsio on October 3, 2005 10:58 PM

I am an alarm installer. To respond to vslo, the two wires that you are seeing in your alarm panel are the result of a rushed or lazy install. ALL phone connections (phones, alarms, computer modems, etc.) Require two lines that carry an AC current into your jack or in this case, the terminals to the dialer in the alarm panel. The missing 2 lines are the other part of the system that allows line seizure. If you only have 2 lines in your panel then you can set your alarm off and pick up the extension and listen to it attempt to dial the reciever at the central station. There is another issue I am aware of with alarm panels and DSL and that is the number of filters present on the extension lines in the house and whether or not the wires to the alarm panel are also wired in with the computer extension line. The best way to get your alarm to perform properly and get the best crappy dsl speed you can get since you were too cheap or unlucky to get road runner, is to run the computer line directly to the phone interface outside (the "demarc") and run the alarm wire directly to the interface and seize all the lines that remain. It isn't perfect because you still have a line that can interrupt the alarm transmission if the computer uses the modem or you have a fax program. But its the only way to insure your signals will go through every time otherwise.

Unfiltered alarm panels can sometimes become unusable for some mysterious reason. As if the digital noise from the phone line corrupts the data in the panel and makes it do very unusual things. Most panels cannot send signals on unfiltered lines but sometimes they will. I suppose some of this may be due to the distance from the central office being toward the maximum allowed to get dsl service.

As to using dsl filters provided by your provider, you can do that if you want. But line seizure becomes a real chore. Its better to get the RJ31x dsl filter made for alarms and skip trying to split it at the box. Depending on your level of skill at wires and connections, you may just be causing yourself headache unless you really understand what you are doing by cutting your rj11 end off and rewiring with splices on very very thin stranded wire that doesn't like being spliced and is difficult to work with even for me.

Good luck all, and consider that with road runner, you will get far superior performance and none of these issues whatsoever. That is unless you get digital phones....but thats another story

I've read the posts here, but no one seems to suffer from the problem I'm having. Ever since signing up for DSL in the summer, I've had noise on the lines when using the telephone. Turn off my DSL modem and the problem goes away. It's very annoying, but aside from every conversation sounding like the other person is taking a shower, I've had no DSL-related problems. Will the RJ31X filter solve this problem? Thanks!

Posted by: D. S. Pope on January 2, 2006 4:37 PM

I am having the same problems...static on my line with my alarm and dsl. Has anyone bought the rj31x to resolve the noise or static on the line issue? Thanks!

Posted by: Matt on February 1, 2006 7:44 AM

ok, i'll be hooking up verizon dsl for a relative and verizon told me all i need to do is put 1 of their filters in line with the alarm system. is this true?

Posted by: andrew on March 23, 2006 9:17 PM

Hey Kevin, not everyone has access to Roadrunner.
Doesn't mean we're cheap! Just not in their marketing area.

Posted by: Myles on October 22, 2006 12:12 PM

I don't know about you all but I have ATT DSL and a DSC alarm system. I've seen on most alarm systems that the jack to connect the filter to is INSIDE tha alarm box. While mines is simple wires going in and out. Not like Derrick Dales but the 2 pairs of wires. Where do you plug in the filter?????????? Can anybody give me different ideas? PLEASE??????

Folks, so what was the final verdict - I have ADT and would like to put DSL on same phone line. I see 1 pair (2 wires - 1 red and 1 black) going into Alarm Box. Should I put a filter between the "1 pair" coming from Phone box to the Alarm box - let me know as ADT would like to charge $196 for this. thx
