Smashed 7208 Leads to CICS and Telco Fail?

This one is puzzling me. Any answers you may give would make my day.

I have supported this one CICS 4.1 unit for at least 4 years, maybe longer. The thing is as reliable as hell and I love it.

Three days ago a troubled teenager completely smashed a M7208 during a handsfree/speaker call with an outside line. The entire system went down immediately. My client recycled the power to the system after disconnecting the broken phone.

When the system came back they found that the CICS Line 1 was completely silent. Upon more testing I found that port 1 is dead, no matter what pots line is punched into it.

As an added complication I noticed that the physical telco pots line that was connected to that port was humming badly and was also dead. The Verizon field tech said that they had to replace "a badly blown card in the CO"?

This CICS unit has a single 4 line loop/pots card, a NAM that answers all 4 of those lines with an autoattendant.

Questions?
How did the smashing of this phone lead to such a massive chain of destruction?

Is there anyway to reset the Line 1 pots loop, or is it dead requiring me to purchase a new loop card to get all 4 incoming lines again?

If I do purchase another loop card, can I simply move the one with 3 working lines to the second slot, making for a total of 7 available pots? Is there a license that needs to be entered in order to use more than 4 loop/pots lines?

Thank you

Smashing the phone wouldnt make the line card go out in the central office, sounds like a open cable pair... No licence needed to add 4 more lines just the card. If lines 2-4 are working just added the second card in program 25 as line one,You will have 3 more for the furture use..
 
They are all related. This setup has been stable for years.

On the Loop card, there are fuses that are cloudy. Does anyone know what the fuse is rated for? Not labeled?

 
It sounds more like the teenager was talking to someone when Telco had a problem with the line.

That blew up your card (probably due to power surge on the line).

Teenager thought the party hung up on them.

Teenager smashes phone.

could that have happened?
 
No the initial cause of the entire thing was a the kid smashing the phone. This system is at a foundation for very rough kids. The kid did this in front of a bunch of people in the meeting.

I wish you could see the phone, he demolished it! Makes a lot of sound when you shake whats left of it.

His action, shorted something that caused some sort of spike through the CICS loop, all the way to the Telco CO.

It boggles me?
 
don't mean to disagree but like justatec said don’t see anyway that could have happened by smashing an M7208. Hope everthing is works out there.
 
I've never heard of that happening, but life is strange (and so are people according to The Doors).

It sounds like line one in your trunk cartridge is putting a ground on the telco's pair.

If you need all four lines on that card then you will need to purchase a trunk cartridge.

Yes, you can put the other line card in slot two for three good lines but there is a possibility that the whole cartridge will fail before long. I would use permanent marker on the cartridge so you will remember down the road what is wrong with it.
 
The only time I had anything remotely related to this, outside of lightening, where it got the line cartridge, fuse link, and CO card was a loose neutral in the electrical plant.
 
yeah I agree with hawks. The phone was smashed after a telco failure.

An active phone can be dropped in a lake and the only thing you will have to do is repalce the set. There is no way smashing a phone can blow stuff all the way to the co.
