I am having my first problem with a DSX 80 installed 9 months ago. It has, until now, worked perfectly. I just added two more digital stations 311 & 312, placed all six line appearances and enabled ringing on all 6 lines (2132) to Always. No matter what I do, I can't get these two new phones to ring. I left the 3112 at default and was able to program the rest of the stations to ring per need in each department. I thought it might be a port problem but after swapping ports and phones, the problem persists. What am I missing. I know the DS and the DSX series quite well. I sell the NEC line exclusively and am surprised by this trouble. Any suggestions? :shrug:

what does tech service have to say ?

They say it may be a defective station card. I have ordered some spares and when they come in I will try to replace the card. This just happened yesterday so I am unsure how to procede. Everything else is working great including the voicemail.

have you tried disabling ring , reseting the system then enabling ring ?

also try taking ring away from a couple of stations , maybe there is a limit to the number of stations that can ring at one time

Have you tried frogging cards to see if the problem follows card or slot? Thanks Jason

Are the lines set to key ring or are they ringing a ring group? If they are ringing a ring group make sure 311 & 312 are in that group.

If you've checked all this I'd definately try resetting the system, maybe even upgrading to the latest software...

"frogging the cards" , I know what you mean (swap cards, take a working card in the system and swap it with the questionable card. By the way good advice )

But let's get back to this word "frogging", 30 years in the businees and I have never heard that word, is that a redneck word

Walter

Walter, "Frogging" goes back to "leap-frogging" cable pairs to make a line work. (White-Blue pair bad, cut to Violet-Slate from pole 1 to pole 2, cut back to White-Blue)

Now then, , Al, the suggestions here are all good. Do you have a test jack to test the output of the card at the backboard? Does it work there? Make a test jumper to plug into the station card with only this port wired out to the jack. Does it work? By then a spare card should be available, try it. Until you know if the problem is software or hardware you are not going to be able to follow this through. By testing the hardware you are left with software if the sets do not ring. That is where the ring group, et al, comes in. Go to a correctly ringing set, do a "Copy" and see if it is ringing now.

Good luck.

So no one has confidence in the Tech support answer ??? :shrug:

Speaking for myself, I had a persisten problem with a loud hum on the line (system grounded, updated, tested at office/no hum there).

In the end Tech support sent a modified line card (This was a known problem). Problem went away.

We also installed a 40 where line 1 would drop the call after a few seconds (no variations in line voltage). We called and they sent us a replacement system. Again, problem went away.

I'd be inclined to follow tech support...
