Hey Mark.
You KNOW I would have busted a nut by now. I think the bunny has some good advice. I'd try those tests before I headed for the rodeo. Can't really see you in a barrel anyway. Good Luck.
dialin'

Hey Dave,
Trust me I DO know that your head would have exploded about 2 weeks back and my noodle is close to the popping point now.

And yes the Bunnie does have good advice "Thank you Bunnie"

But what I have done before I do anything else is that I've Ordered 4 of those AM radio stopper filters and then I went to the customer site today and showed him that he has Christian radio on all of his phone lines coming in right up to the backboard "he shrugged and walked away" I also pleaded on bended knee for him to ask his main office to let me go in after hours and let me do my thing. "He'll get back to me on that"

Until then they're working off the compact.
My line in the sand has been drawn "sorta"

Aye Aye Captain Bunnie : )

The sleeping bag order made me laugh, thanks I needed that.

I ordered the sandman AM radio chokes and I'm pushing to get in there after hours,so until the gizmos arrive I'm stepping back and giving my brain a rest. The customer is on the Compact and it's working fine and I'm on the 7100 which is also working fine.

Thanks again for all of the input and if a solution comes out of this mess, I will definitely post it.

I wonder if the 7100 is seeing the AM radio as a ring signal... AM can really do wonky things to computerized electronics. Any RF can, but AM seems to be more scary because its power is varying in amplitude.

Oddities i've seen in this matter: a trucker friend of mine had bought/built/modified a 100 watt AM power amplifier for his CB radio. He could make city traffic lights change just by keying the mic.

I once crashed an old Meridian SL-1M simply by keying a 2 way radio in the PBX room. (i was a dumb army private and didnt know yet, the base commander was pretty unhappy and i was sent back to RF from telecom)

Hope those filters work for you

Did you ground all the unused pairs coming from the demark to the 7100/compact?

Did you ground all the unused pairs at the demark?

The AM is coming right from the CO DEMARC on all 5 lines: 4 into he switch and 1 to the fax, if I clip off on TIP and hold the ring clip in my hand and touch the CO ring side with my finger "in Monitor" I pick up the station and to pump up the volume I tap the ring clip to the ring CO terminal screw and it becomes as loud as a transistor radio...Haaaaallalllooya

I also was told yesterday via email through my distributor, that Samsung told them that Yes AM RF causes the 7100 to phantom ring but there isn't a tech bullentin or anything else in writing about it.

I received the AM filters today so I guess I'll find out on Monday if this works,also I haven't had 1 Alarm or blip on the 7100 since I've been using it for almost a week now.

Good Joke BTW and Happy Thanksgiving

The CO provider is responsible for providing clear dial tone. It's facilitative for your customer that you bought the filters, but it is not your obligation.

If the COs are not clear, get a meet with the provider and have them fix it.

I will after I put on the filters and I make sure that it clears the trouble.

Other than that I think in reality at least in this case I'm in a no win situation because the customer's not going to be able appreciate the fact that I busted my butt to find the problem, all they'll remember is that they bought a new system and it took the phone guy 3 weeks to get it working.

AT&T may clear the trouble on their end, but that's about it.

Samsung's not going to compensate me even though they didn't make their new systems as solid as the old systems regarding trunk issues, the very least they could & should do is put out a tech bullentin and inform their tech support people, instead of telling people to swap cards and reprogram the switch by hand etc.

Nope, if this works I will just walk away and hope like hell that I never hear from this customer again.

Assuming that the filters either you or AT&T puts on allow the system to work, why would you not want to keep them for adds, moves and changes? They didn't do anything wrong, they trusted you and bought a system from you.

No, I'm sorry if it read that way. I'm not blaming the customer at all, I'm just getting very frustrated.

I installed the Filters yesterday on the 7100 that I ordered and watched the calls for over an hour, but just as I was driving away the customer called my cell and said it was flaking out again, so I went back inside and did the following:

1) connected 4 SL sets in parallel with the 7100 to see if the phones would ring when the switch flipped and they didn't

2) Disconnected and shorted the main # after 30-45 minutes all the lines lit up at the same time.

3) I did the same on the 3rd line, same thing. Even the lines that didn't have a CO connected would ring. I also moved the lines around on the TRM ports. I didn't do lines 2 and 4 because they were closing.

I ended up putting them back on the compact and the trouble went away.

I called the line tech for AT&T and he was going to talk to his supervisor about putting chokes on their side but I haven't heard anything back yet.

I'm also going to try another MP10 when that arrives and see what happens. The only thing left after that is the cabinet.

I used the 7100 at my place for over a week and not once did I see this trouble happen, so logic says that it's coming from their lines but I'm not sure of anything anymore.
