Hi Gens
on a Nortel Norstar 8 x 24 Compact ICS
in system programing Music on hold :y, background music:Y
oi tired Pin25 on Amphenol port Connector and Pin25 on Line Connector, it did not work, i can hear the music with But set, Feature 86 gives dead air on the phone speaker
where did i go wrong
or i am on the wrong PINOUT

Thanks
Serge9
 

i tested Pair23 with Ohm meter
it showed 1.92 one time, and 1.85 another time
connected the music source again
feature 86 and music on hold were dead
i pulled out pair23 and connected the nusic souce directly to pair23, guess what
with feature 86 we can hear a very low volume but it is there
music on hold still dead (calling from a cell and asking the user to put the call on hold)

i will try replacing the 1/8 in lug converter cable
but why feature 86 gives very low volume music and music on hlod is dead

Thanks

It is progress. Before you conclude that MOH is dead for outside callers, try a landline. Your cell phone may not be sensitive enough to pickup the low volume music source. A related topic came up before about MOH distortion on cell phones.


Once you have the physical connection corrected, you can double check your programming for MOH, and then work with the volume of the source. Please keep in mind the limits I posted earlier so you do not overload the KSU components.
 

thank you all
i did F86 and raised the set volume to max and the sound was very weak

Thanks

Less than 2 ohms is basically a short. Glad that suggestion helped you track the problem. I'd still try Curly's suggestion to sub another amp cable. Small chance the short is in the cable or connector.

sometimes overlooked with MOH is the input. If you are using a stereo plug it will have a right and left channel. each has a n insulated wire and an uninsulated braid.This has to be wired mono. into the system.The 2 insulated wires are connected together for one side and the 2 braided wires are connected together for the other. if you just use the 2 insulated wires the volume goes to nothing.

thank you demrispapa's for valuble detail you have supplied
(the plug i used is a mono plug and was used on another system (MICS))
i am trying to think of every possible cause, so since i have not open the plug to verify how it is made
i bought a new mono plug, wires and connecting box, will make my own plug and test it on wedensday
 
Serge9, can you clarify two things for me?

1/ Can you hear the audio on the bix, after you punch down the wire from your radio?
2/ You said the ohnmeter reading was 1.92 and 1.85,.. Is that ohms, or kOhms?

Something to try while you are working with the amphenol connector. Listen to the audio on the bix while you are pulling off the amphenol connector from the CICS, if the audio goes loud with the amp removed from the CICS, the cable is not shorted, the CICS is loading down your source. This may or may not be bad.
 
What a story
The music is on!
** i bought new Lug cables
made my own lug plug, and got one made by a friend, a tech who works on suffisticated printed circuit.
** got another AMPS
and went to see this system, verified the installed AMPs,
the cable was of the older system, it had one screw at the higher end to secure it in place, and this system does not have a hole to screw this screw in!, the screw was screwed in a bit too much = lifting the AMPS just a milimeter or 2, so it was not sitting properly, unscrewed the screw, pushed teh AMPs in, could not get a good volume
replaced the music source and lug cable and it started to sing
Thank you all for your support and generosity and good blesse you all
