Re: [on-asterisk] alarm systems
Jim, Thank you for that very clear definition. The issue though is trying to get a voip line to support an alarm (which seems to be no issue now) and a postal machine. Apparently, the postal machine does some special look on the line for um. It doesn't work like a fax or modem. So, it doesn't pickup the line, look for dialtone and then dial. it apparently picks up the line and looks for some noise and then initiates communication. All I know is that it definitely does not work with ata and voip lines. So, I am looking for clarification so I can get around this.

RE: [on-asterisk] alarm systems
Due to the compression issue on VoIP many analog data services (modem/fax/etc) don't function _reliably_. Making sure you use a codec that does not compress and removing error correction can help but still does not guarantee success. As for alarm systems. Some companies now offer TCP/IP communicators that send the same signals over IP to the central monitoring station as due the analog communicators. DSC is one of the companies making such devices. However, you must have a monitoring company that supports the data coming in over IP. There is also a different pricing structure for this service.

Re: [on-asterisk] alarm systems
Dean, To me at least an analogue line is the traditional home telephone line - if you can plug a regular home telephone in and get a dialtone, that's it. Some alarm systems - to my understanding usually places like banks or jewellery stores - have a special service (I don't recall the official name) which is an always open connection from your alarm panel back to a receiver at an alarm company with a continuous heartbeat to overcome the possibility of someone just cutting the line. These don't have dialtone. Assuming that you have just an ordinary PSTN analogue line, is it possible that the line is also being used for a DSL service? If you don't have a suitable line filter to block the high frequency DSL information I could understand that there would be issues with devices like alarm panels, fax machines, and such. Some DSL services are delivered on a dedicated local loop - ie a pair of copper wires from your premises back to the nearest CO - that does not try piggy-back regular voice service on the single pair of copper wires.

Re: [on-asterisk] alarm systems
Your referring to a DVAC line, this is digital direct connect to the monitor company. This is not that. It is bell services. Yes, you can plug in a standard analogue phone to is and make it work. The issue is that the local loop has some digital qualities to it. Just trying to figure out what those are. The mailing machine in peticular looks for squelch on the lines. And I believe that over fxs to voip this is an issue. just wondering if that is the same with bells Local Loop offering.

RE: [on-asterisk] alarm systems
A local loop can also be a line that passes by Bell Canada switch but eventually gets the dialtone from localcomp (local competitor like Rogers) as Bell Canada techs term it. Bell Canada provides the line and the line to goes through their switch in order for them to be able to test the circuit when needed. I believe localcomps then interconnect at CO. Otherwise at OPI or JIWI it's still Bell's equipment. Who do you pay your bills to? Bell Canada?

RE: [on-asterisk] alarm systems
Dean, Take this with some salt... I am no guru on this stuff but for some reason my brain is popping into my head the word 'closed loop'? I think this is something specific for Alarms... it's been like 15 years since I was involved with an installation on one. If I recall, it was a way to wire the Alarm jack (or a special RJ-?? jack) that cuts off communication if the line is picked up at that jack. I assume so someone can't trip the alarm and just pickup the phone and screw up dialing/communications to the alarm company to report a trip. This is why you have to wait a minute or two to be able to make a phone call when an alarm triggers. That's the only thing I can think of, maybe this will trigger someone else to chime in and say I'm completely wrong. -Original Message- From: Dean Yorke [mailto:dean.yo...@xyc.ca] Sent: Thursday, March 05, 2009 4:29 PM To: asterisk Mailing Subject: [on-asterisk] alarm systems Hi All, I know that this might be a little off topic but...

Re: [on-asterisk] alarm systems
Analog line refers to a standard 600ohm-48v line as opposed to a VoIP
(data)line.
Local loop refer to the analog circuit, the loop being the circuit that is
set up between the local exchange when the telephone goes off-hook (it
completes the circuit and thus
draws current)
Your alarm should be connected to the local loop via a special jack (RJ31X)
This is designed to disconnect any phones from the circuit should the alarm be
activated
This is so no one can cripple the alarm by calling in,calling out or (in the
case of an inside job)
leaving the phone off the hook. IF you have DSL on this line it will also
disconnect the data connection.
These alarms can only use analog lines unless the jack is rewired.
Hope this makes things a little more understandable.

I am also interested to know how the postal machine through voip lines. In
the past I tried several times no luck. Any one share your experience.

The only difference is the features that are included. It is still a
regular analogue line served off the same equipment at the Bell CO as every
other line.

yes this is what i am talking about?
is there any difference with a standard analogue line?
also, anyone have any luck with a postal machine working over ata and
voip lines?
thanks for the responses!

by Bell. It is an analog line, it is not digital.

Sorry, local loop line is a service that has call features like call
forwarding and call display and caller id.
but it is different that the service for a standard bell line like
home. I think it has a little digital service.
Thanks

Hi Dean,
I think local loop refers to a dry-loop so you do not have a
dialtone on those lines thus they can only be used for DSL
services...

Wondering if someone can help me understand the difference between
an analogue line and a local loop line from bell.
we have a couple pieces of equipment, (pitney bowes mail machine
and personal install alarm system) that are having issues
communicating on these lines.
Thanks

Re: [on-asterisk] alarm systems
There seems to be some misunderstanding here. This is probably the best way to understand a local loop: The local loop is the pair of copper wires that run between your premises and the Central Office, through which the carrier delivers a service. The carriers generally refer to all this collective copper infrastructure as the Outside Plant. I suppose a local loop could be fibre as well, but I think most people would be best to think of a local loop as a copper connection. It is pretty much pair of wires that run from your premise to the circuit terminating equipment provided by your carrier (there may be some cross-connects along the way, but that loop is dedicated to your premises). - If they connect your local loop up to an analogue card, you get an analogue line. - If they connect your local loop up to a DSLAM, you get DSL. - If they connect your local loop up to an HDSL unit such as a PairGain, you get a T1. - If they connect your local loop up to some other thing, you get . . . um . . . some other thing (I'm thinking mostly of old services that nobody ever orders anymore). Traditionally the carriers would--by default--connect copper loops to analogue circuit packs, and then simply program the circuit up if you want dial tone. This is why a dead line will often have battery (which means there is voltage on the line and you can hear sidetone, but no dial tone). A 'dry loop' refers to a loop that has been disconnected from the analogue circuit, and not provisioned for any traditional carrier services. If memory serves correctly, it's called 'dry' because it's disconnected from the batteries (which are 'wet'). It's really more of a pricing and tariff thing than a technical thing, since they may not bother actually disconnecting the wires. The point of a 'dry loop' is that you are having DSL delivered on a line that would typically also have an analog circuit on it. Does that help? Note: Local Link is a bundle of features that are delivered on an analog circuit. Link refers to the fact that you can press the Link button on old Nortel phones to perform a hookswitch flash. Local Link service offers all sorts of features that you access via the Link button. Since Bell and Nortel were once the same company, Bell uses a lot of Nortel-speak. You can also get Link type features on your home phone. Bell just doesn't call that Local Link even though it might be very similar or even identical from a technical perspective. Clear as mud?
