White noise not music

Big Lucy just installed MOH on a SX200 and all you get is loud white noise. I'm using a DNIC with DMP. even with the music source pulled off and when CDE 18 is filled in the white noise will come instead of music when transfering or on hold. Big Lucy has tried other ports same same, any ideas?
As always thanks in advance for your help

are you sure the DMP is connected to the right port. In form 9 does the type say DMP?
Pair 25 of DMP is connected to DNIC port. If all this is correct you may have a defective DMP.
Have you tried using a ONS port?
 
Big Lucy is programming remotely the on site tech installed the hardware. He is getting music (thru his butt set) in on O/R pair and out on the V/S pair. I have programmed DMP in CDE 09 added the plid to MOH in CDE 18 and show it as music source in form 19. Even when I program aonther port in CDE 09 without even having music source hooked up loud noise.
No I haven't tried a ONS port this seemed simple enough

Ons ports if newer software and a SX200 is cheaper than DMP.
If you program in form 18 you don't need to in form 19 and vice versa. Form 19 and different tenants would give you multiple tenants with multiple moh, but that is not your problem.
A DNIC port will give you a loud noise if you listen to it with a butt set.
You say your tech hears music ok going in on pair 7 and out on pair 25????
The switch sees "dmp" in form 9?
 
That is correct music in on 7 & 32 out on 25 & 50 R/O V/S pairs. I notice in the e-doc on using ONS that it warns not to program the switch till after the music is connected I had programmed the switch before the tech was on site. The e-doc suggest to unseat the ONS card and power down the bay
then try again with the music source connected before programming. Do you think this may be my problem?
 
you are not using ONS so don't worry. You do NOT have to power down the bay or unseat the card for ONS MOH, just deprogram it connect the music and reprogram if using ONS MOH.
 
If your DMP is connected to a per node, the issue may be in your system option settings for the Peripheral Control Card. Check to make sure that if you have a triple CIM or Triple FIM that the option is set to 3 instead of 2. Visa-versa for Dual cards. The channel that is assigned for MOH is different depending on the type of card.

Is the lamp on the DMP Steady red?
What is the status of the port in maint. Does CPDWA detect a DMP(During status press 1)?
 
No per node. I asked about the LED and the OST said that it was no lite (not a good thing) the port shows idle but not a DMP in status. wonder if he powers the switch down and back up if that would clear it with out the DMP installed?
 
powering down is a last resort. Check the amphenol cable as pair 25 for the DNIC is at the heal, maybe not seated properly. Also the punch down on the connector pair 25 on the Bix or whatever you have terminated the 25 pair onto.
 
The light would be flashing regardless of programming. There is no connection. Ditto on check the amphenol. The installer is trusted enough to know the BIX layout? You might want to ask the pair number that they've connected to.
 
If you have a peripheral bay (node) on the system, using an E&M trunk card for your music on hold (or paging) seems to me like a lot easier, possibly even cheaper, plus everything is contained in the peripheral cabinet and you don't have to worry about where to put the DMP or figure out how to wire it, put connectors on, etc. I'm just kind of 'old school' on some of this stuff. MOH & Paging is basic telephony-101.
 
he said when he went across V/S pr he got music on his butt set which would have went in on R/O and out on V/S. I went into another 200 and programmed a DMP to a DNIC port and dialed and transfered and heard silence. when I do the same same here I get that loud static even with the music source off on any pr of that DNIC card the stations on that card work fine
 
The E&M solution is not available on the Sx200 as far as I know. When testing MOH, use the Feature Access Code for Tones (33 = MOH if memory serves)

I am somewhat surprised that you can hear MOH on the V/S pair as this is the digital pair running the DMP. I must admit I've never tried that though.

I think we must be overlooking something that would otherwise be obvious. Until you can get the red light to be on and steady, this is not going to work.
 
He should not hear music on pair 25 (V/S). If he can hear music on the V/S pair wouldn't that suggest that something somewhere is bridged or backwards? It sure as the dickens would explain the white noise.
 
the white noise he hears on pair 25 is the noise you would hear on any DNIC port as this is coming from the pbx and is the digital noise.
Again I would confirm wiring and amphenol.
If this has feature level 4 I would try the "ons music on hold", cheaper and probably would be working by now. Do that have the tech or you try on another switch or lab switch.
 
Thanks to all that helped on this it now works fine my on site tech had issues with his wiring up the 110 blocks kwbmitel really helped with the maint show status then the device type it wasn't a DMP but a ?DNIC which meant it didn't see the Music module
Thanks again ALL
