Can a short on a wire to rj11 input jack cause damage to system phone or to port?

I've personally never done that on a 6X, but my first guess is --No. On the line ports, if you short them on the DMark--it would just be a "busy" and on the S/L ports, my guess is that it would be the same---but I'm not totally sure. I've never seen a short on a S/L port or C.O. port cause damage on any system. Now, digital ports that have a power pair---that's something else. I've seen quite a few blow in that scenario.

What has happened? Have you lost one of the ports?

Yes during a program of an existing security system our customer lost port 1 and one phone now not working after 4 days of working. Trying to determine if posible what would cause port and phone to crash.

Do you have the Allworx on a good UPS?? I've had a surge (spike) knock out a paging port. It was on a customer-owned UPS that turned out to be no good. Were there any electrical brownouts or outages just before this happened??

Are you talking about port 7 (s/l port) and a s/l phone not working---or are you talking about port 1 (C.O. port) and an Allworx phone not working??

Is this a new installation??

Also---you mentioned programming of a security system that seems to be related (time-wise) to the port failure. Why do you think these two are related? Just curious.

I don't think it is but a customer with a problem with there phone system does.

OK...now I get it.

The simple act of crossing the pair on a S/L port is not(in my opinion) going to cause a port failure. However, if there was an introduction of some sort of AC or DC onto those pairs---now that's a different story.

Programming a security system when it really has no physical interaction with the S/L port wouldn't (in my opinion) have anything to do with any port failure. Just for kicks and giggles, I'll run this by my techs and see what they think.

Is the 6X under warranty?? If it is, and the port just went bad---then it would be covered. If the 6X is sent back to Allworx and the customer gets an advanced replacement---the Allworx tech guys do component tests on the port and can tell what the cause of the failure was---either a breakdown of some sort or an induced over-voltage scenario. From talking to them, they do tests and also pull out the microscopes to see what they can see. They would be able to tell the customer what happened to the port. If they determine that it was an over-voltage factor---then the warranty would probably be not in force. Now, I'm just talking from my personal experience----they have a 24 page document, I think, explaining the details of their warranty.

thanks

Have not had that happen on an Allworx, but I've had pins melted on a talkswitch FXO port due to a short/faulty wiring in the alarm panel. CO went to line seizure device in alarm panel then out to talkswitch. Most alarm installers I've seen do not properly ground their equipment.

Good point. I talked to Dave our main tech, and he said about the same thing. "...during a program of an existing security system...." doesn't indicate that anything would happen---however, if there were some physical problems (faulty grounding, faulty security hardware) then introduction of foreign electrical voltage might be a possibility.
