Ahh that IS a good idea...if I were to do that, I should just call one of my DIDs? Also, I assume I'll need a T1 style crossover cable for that?

PS - if anyone knows a reputable Comdial/Vertical dealer in my area (Bucks County, PA), who could deal with the DXP, I'd be interested in knowing. Our current dealer whom I used to really like are seriously dropping the ball - called twice to see if they could try swapping the syn card for us - no call back.

PS - If I do the connect the PRI boards, would I have to switch the sync card for it to provide timing?

FYI - Just tried it using a T1 crossover cable, and while the lines showed connection, they showed as disabled on my line console. I couldn't make any calls across them. I tried setting the sync bother to auto and manual with no changes.
I reconnected PRIs, rebooted the system, and tried both options on the sync card again, changing both the timing switches and what line it gets timing from (pri/sec), and nothing changed. Still have echo. Made several calls home, and in most cases I could hear myself, then 2 of the calls my mom could hear herself echo but I could hear it.
One key thing seems to be that when the call is answered, there's a loud PSSSHT noise. That seems to be consistent with the static.

Finally got a hold of someone with some pull at the vendor - they're going to send someone out to do whatever they can to test the DXP, be it swapping the syn card or doing the crossover trick.

So, did your Vendor show up yet? How did you make out?
I can see the light at the end of the tunnel..

Well they came out yesterday and swapped the syn card, but it still echoes. They mentioned the crossover cable test would work but with a lot more work than just plugging the it in - he mentioned something to do with the dip switches on one of the PRI boards would have to be modified, I guess to assign FXO capability to the channels instead of FXS (hopefully that makes sense).
He verified the wiring looks ok and we even put a loopback adapter on each PRI board to see if it would sync to itself. They worked fine.
Back to the carrier! Two calls into them today with no return call.

Has the carrier checked the echo canceller in the central office or, if it is fed by a SLC or Lightspan, the cards in there? Intrusive tests basically just test the loop(cable pair/s) from c.o. to smartjack.

Well the quick update is that I called the carrier again over and over until I got a live body. He is having them do instrusive testing again tonight, and also dispatching someone out to look at the lines physically, I guess from Verizon.
I got the echo myself a few times this morning, even though I'm one of the few that doesn't see it much. I don't make nearly as many calls as others in here do though, for our sales people thats all they do.
Another ironic thing is that when I call the carrier, I always hear a clicking/popping noise, that I can best describe as a hookflash. Its only when I call them though, and the guy swears he doesn't hear it. I still think its on their end.

Clicking and popping on a PRI is typically caused by slips, in my experience.
