Noisycow,
Sorry I missed your post, I forgot about sandman that may be step 4 before the rodeo clown career thing.

Thanks

I looked up DACS and now it has me thinking (not saying that's a good thing) but here it is:

A few other odd things happened at the customer site.

1) Their DSL was down when I arrived onsite with the sync light steady on but no access to the net and it was wired and filtered direct to the fax xxx-3861 that line wasn't going into the 7100 so I left it wired as is. The DSL tech was already coming out to work the trouble so I ignored it, that was also the day that I called in trouble on the CO's when the ringing started and AT&T confirmed trouble (opens) on 2 of the 4 lines going into the 7100 and then sent another tech out to deal with those, I also believe 1 of the lines was a recent addition because the customer complain to me about how long it took AT&T to get the new line in.

2) At one point 2 lines rang in simultaneously on the 7100 and the customer lost internet at the exact same moment and remember the DSL line wasn't on the 7100.

3)I left the building for 30 minutes to run to the hardware store and when I came back the customer told me that the fax number was now ringing in on line 4 on the 7100, so I ID the line and sure enough the fax number was on line 4 and line 4 xxx-xx66 was on the fax and I know I didn't change any wiring on the backboard BUT their DSL was synced up and working, by now my head is spinning and I'm questioning my sanity.

I tried to explain this to the customer but I might as well of been speaking Martian to him and his response was "just fix it" so I rewired the MDF and sent the filter xxx-xx66 back into the 7100 and routed the xxx-3861 fax line back into the fax.

I guess the bottom line question is: the AT&T techs have been treating this like a bad pair issue, but is there a likely possibility that they may be using a DACS down the line and the configuration is screwed up?

By the way before the 7100 they had the 4 line phone circuit city setup, they said it sucked but didn't go into great detail.

I have no idea if DACS is used over the pond so wouldnt really rely on that. But from the above it sounds like its a problem with the lines not the kit.

Stick the DCS on a prove it from that.

Here's the update so if anyone has any input feel free.

Monday: I arrived onsite at 7:45 am with the DCS compact programmed up and cabled for a quick swap out. AT&T wasn't onsite.

The 7100 was quiet as a mouse, I punched 701-704 for DT all good and clean, I sat there from 7:45am until 9:00am watching all the incoming and outgoing calls, since everything was working perfect I decided not to move anything over to the Compact, half thinking that AT&T worked the trouble out over the weekend.

I told the customer that they were still on the Original "New" system and since everything was working that I would go do another job and to call me if it flips out again.

11:50am: I get the call that the lines are going crazy etc so I head back to the customer site.

12:30PM: I walk into the building and asked if the phones were still going nuts and they reply Yep.

it took me less than 10 minutes to move everything over to the compact, all the lines are up and working normal and I wait to see if they flip out...nothing

I sat there from 12:45pm until 3:30pm and the 6 year old compact system worked perfect so while I waited, I blasted the 7100 with 4 analog ports from the compact and it seemed to be working fine too, I also copied the alarm report from the 7100, here's a portion:

Could these alarms just be me unplugging DT etc.?

If you notice that there is nothing happening at all on the 15th SAT or the 16th SUN when they are closed.

Also while I waited I had a new 4trm overnighted
and cleared the media card, defaulted the 7100 and uploaded the programming back in.

As it stands now the compact is still the working system, but I'm a little less than confident at this point that the new 4TRM will solve the problem.

any ideas?

Is AT&T willing to monitor these POTS lines for a few days?

Can you set up your amp cables so the end user could just plug from the 7100 to the compact if you are using the 7100 and it gets the heebie jeebies? It would take some time to set up but be less pressure on you.

AT&T: I doubt it, but I've been reading up on the high/low line current issue after Pots posted, so I'm going to meter the lines tomorrow and see where that takes me.(maybe to Mike Sandman)

AMP Cables: I already have it set up that way but as far as the end user goes, lets just say he's not technically incline and doesn't want to be.

What I may do because "I" have the "heebie jeebies" is let the Compact run most of the day tomorrow to see if the lines freak and when I do put the new 4trm in I'll leave the compact as the main for a day or 2 while tapping off the CO's into the 7100 & 1 phone and then monitor it before I swing it over and keep my fingers crossed.

Another update and I hope I'm not boring anyone but this has kind of become my journal of events.

The Compact has been running like a top now as of 5:00 pm today "Tue" I went to the site around 2pm with the replacment 4trm and swapped it out but I didn't move them over to the 7100 yet, instead what I did was leave the compact SL exts 209 through 210 fed into the CO ports of the 7100, put the compact into night mode which routes 701 to SG 501 with ext 209, 702-502-210 etc. and I'll let that ride until tomorrow afternoon, I'm not sure if this will be a valid test but at this point I just don't have the stomach for it to just swing it over and wait...

You are not boring anyone, the 7100 seems to have fascinating bugs in the Chinese sense.

Thank you I appreciate that, but as far as 7100 bugs go I haven't been able to find anyone or any tech bullentin with a similar trouble, I sent an email via my Distributor to Samsung tech support first thing this morning but haven't heard anything back, Because if this new 4trm does the same thing after I connect it direct to the 7100 (likely 2+ hrs after I leave the site)the customer's heads going to explode and he'll think I sold him POS equipment and/or I don't know what I'm doing, either way not good for me or my reputation, not to mention my pocket.

So I would like to find out before hand if Samsung found the if above or below xxMA causes crossover mass ringing or something like that.

I still haven't metered the lines yet, so I'll need to do that before I swing it direct, but if it's just happening in spikes at random times during the day...ok now I'm over thinking it and just stressing myself out..lol

Make sure you take different readings... including when a line is ringing.
