M3904 line issue

[jgeisler1]

I'm having an odd situation in one of my offices. An M3904 phone stopped working (did nothing when buttons were pressed even though it had a dial tone), so I assumed it just died and brought in a replacement M3904. When I plugged that phone in, the speaker randomly started going off and on without me pressing it. The display was also extremely dark when it is first plugged in. I checked to make sure the TN was Digital and not analog, I disabled and reenabled the line with no change.
I'm not sure what to do at this point.

I have printed out the TN of the line just in case.

Try another TN? Maybe the TN is bad.

Sounds like fluids spilled on the first and possibly second one was bad. Try the second one in a known good port to see what happens, after that I agree with GH

Last but not least..... move / swap cable pairs.

Have you also tried doing IDU 008 0 10 01 to find out if the system can see that the digital phone is plugged in?.

All the best

If it's working, then leave it alone!.

I seem to remember that when you held down the RLS key when plugging in a digital phone it caused phone to go into a diagnostic mode of sorts. It did on the old 2008, 2616 phones anyway. All the lamps would be lit and pressing any key caused a beep. Might be worth trying this to see if the phone has a dodgy key or two.

 

[jgeisler1]

I went ahead and created a new TN for that line and it fixed the issue. I'm not sure if that TN has died in the card or what happened. I will experiment with the line on another phone to see if the issue persists.

 

[jgeisler1]

OK, the problem has started again even though I used a new TN and a different card in the system. I'm at a total loss at this point. Anyone have any more ideas?

Have you tried taking the telset and plugging directly at the main frame ?
This should prove that the internal wiring is OK or not.
Does the LJU have a capacitor in it ? if using CAT5 do you have the correct RJ45 adaptor
I assume you have tried the M3904 in a known working DN

 

[jgeisler1]

I'm not sure I have the capability to plug the set directly at the main frame since it's just the pair that goes into the block. I am able to tone the line from the source all the way back to our switch room without any problems. I don't know about the LJU (I'm not even sure I know what that is), I'm fairly new to this position and I had almost no training on anything. The adaptor is correct, I even replaced it with a new one just in case.
I just re-terminated at the source and the problem is still happening. I will try a different pair to see if that has any effect.
