Hello,
I'm dealing with a SX-200 Digital (G1004) to set-up MOH that has never used. I've read all "MOH topic" posted on this forum but I'm not clear yet.

We got a music external source, with announcements. PBX has Universal card/ports available. Form # 18 says MOH is programmed on port 02-03-04 (SCT 01). But the thing is I don't get working MOH at all (no internal, no external calls). Form # 4, options 71 & 72 are Not Valid, I mean, there are not options 71 & 72.

Questions:

1) external MOH module (a black box) is something that HAVE to use on this system's version?

2) what are other options/features I should take a look on? (form # 4, 19, COS?)

I really appreciate your help as my customer has bought Music professional system to feed the phone system already.

THANKS.

DO you have MOH module on the uni card?

Option 71 & 72 are for EL systems. Your music should be cross connected to J25, R/S pair.

Bay 2 Slot 3 Circuit 4 Subcircuit 1 on a Digital would be V/G

Thanks to all of you sincerely but I'm sorry, let me see what it's clear to me at this point:

DrPbx: No, I do not have any moh module (neither external nor attached to the card)

fifty5footer: J25, R?S pair means connector J25 on the back-plane, using red/slave pair, is this correct?

johnp: I'm telling you what says on form # 18; what does V/G mean? so assignment to 2-03-04 is incorrect? is that what you mean?

Thanks again.

Violet/Green pair of the 25 pair connector

Hey, I answered too fast; I'm sorry for that ;-)
johnp, you say it's on pair J25, violet-green; and fifty5footer, on pair J25, red-slave, so I will test in both, but, should we use an external MOH module (the black box) necessarily? yes or no? no impedance / signaling / etc. issues without that unit? Thanks for your help.

Form 1 will tell you what is programmed for a bay and slot. It also will tell what is installed.

If the is no module on the card, you will need one for moh to work.

Thanks johnp; that was fast!

Form #1, on 02-03-04 is programmed and installed "MUSIC PAGER MODULE". How can I clarify if there is or is not module on the card? are you talking about a piece of hardware attached to card as I seen in a BCC card (SX-200 E/L)? or that "MUSIC PAGER MODULE" statement is enough to conclude that there is a module already installed?

What type of hold are you using? Is it a digital set hold? Have you put a butt set on the V/G pair to verify your interface… do you hear music on the butt set? Also enable 602 in the COS of your test phone and then turn music on at the phone. This will give you the music source thru a Superset’s speaker instead of testing via hold.

You can verify by removing the card and visually inspecting. On a Digital, bay 2 - slot 3 is lower right, upper level on left. What else is on the universal card? Also what type of card is in bay 2 slot 4?

OOPPSS!!! Shoveling snow for a week makes the mind go numb!!

If we are in agreement, the 600 Ohm output of your music source needs to be connected to pair 23(V/G) of the bay 2 slot 3&4 block.

The module only provides an interface to an external source.

My question regarding slot 4 is if there is a T1, they may have failed to recconnect the cable.

Sorry but I'm on the same point: MOH doesn't work. MOH module is on Univ Card (module # 4). Option # 602 is ENABLE in all COS in use (rooms, trunks, digital phones, console, ...) now.

I took a look on cards and they are as follow:

Bay=02 Slot=03 UNIVERSAL CARD
02-03-01 CONSOLE MODULE
02-03-02 DTMF RECEIVER
02-03-03 DTMF RECEIVER
02-03-04 MUSIC PAGER MODULE (Music/Paging Module 9109-018-000)

Bay=02 Slot=04 UNIVERSAL CARD
02-04-01 CONSOLE MODULE
02-04-02 DTMF RECEIVER
02-04-03 Non programmed
02-04-04 Non programmed

I punched down on pair 23 of J25, MOH amplifier 600 ohm output, I'm able to hear it but several calls on hold and I just hear air".

Any other idea to checking, please.

THANKS.

Could be a bad card, module, or cable. You could move the module to either the 3rd position on the same card or positions 3 or 4 on the slot 4 card.

You would need to make the changes in form 1 and 18

Testing Music-Pager-Module in different UNIV card now. 02-04-04 circuit corresponds to pin 10 (RED/SLAVE pair) on same J25 connector. Is this correct? Thanks.

Red/Slate pair would be correct on same J25 i.e. 10th pair.

Sorry guys, but no good luck so far. I installed same Music/Paging Module hardware on a different MITEL SX-200 and it worked. Also, I moved it to 02-04-03 and 02-04-04, with setting on form # 1 & 18, which implies different UNIV card and different pairs although same amphenol cable, and nothing good so far.
Any other suggestion? some option to set we're missing? Thanks!

Have you checked/changed the AMP cable - or can you move it to the other bay to eliminate the cable?

And as JohnP stated have you verified you input impedance 600Oohms and input level -6 dBm. Its been a while but I remember installing an inline matching transformer to get MOH to work on a 200D.

2-4-3 and 2-4-4 are the same card different module which would be red/orange or red/slate pairs of J25. Are those what you are using?
Do you have 2 consoles and do they work?

About AMP cable and move it, it's not easy. Anyway, there is a console in use in same cable, so all pairs can not be bad.

Regarding input matching, MUZAK (Music On Hold provider) installed an amplifier in line with output of 600ohms, so it not should be the problem. Also, I'm able to hear music with my butt set on all pairs used so far (R/O, R/S, V/G).

Why do you ask about two consoles working? Thinking on replace console module for MOH module?

THANKS.

You may need to reverse T and R on the MOH card feed, or even use an isolation transformer. There cannot be any DC voltage on the input to the MOH card. It will saturate the transformer on the card and no audio will be able to pass to the MITEL 'side' of the card. (TMI me thinks, just make sure there is no DC voltage on the output of the amplifier.)

Asking about the consoles because they are the only other thing that is using that cable and if it was bad or not fully seated into the back of the bay, as I have often found, the signal would not get through.

We're using right now as a feeder to MOH card a McGohan 1 Watt Amplifier (MODEL MS-11), with a 600ohms / 4dBm output. Is this a correct unit to feed MOH module?
I've reversed T/R but no luck.
With my butt set on pair Black/Brown (02-03-01) on 66-block, I hear music but not too loud; and once I take UNIV card out of slot, the volume comes louder. Does it means something about matching?
What isolation amplifier could I use for this matching?
Thanks one more time and I'm really sorry this issue is taking to long too fix it.

"With my butt set on pair Black/Brown (02-03-01) on 66-block, I hear music but not too loud; and once I take UNIV card out of slot, the volume comes louder. Does it means something about matching?"
-------------------------------------------------
That result indicates that you are connecting to something in the cabinet. Can't believe there is something wrong with both Universal cards. Nothing wrong with MOH/PAGE Module. What is left? How about something really duh in programming! Tenant assignment? something in Form 4? Just FYI, I believe the big black wall mount MOH/PAGE box only works on Lite 17 and up. C'mon guys, this CAN'T be this hard!!!

This should just work. There may be some type of memory space corruption. I don't know if a reboot has been done. You may want to delete all music on hold programming then reboot and reprogram. Grasping at straws here.

I think you have a bad MCC card.

OK, after a reboot, keeping all MOH programming as it was before, I GOT!!! music on hold (volume is a matter now but I think it should be solved with a 6dBm amplifier and not the 4dBm is in use now).

BUT it works only if I call internally (i.e. room to front desk) but it does not work if I call from a cell or external line to hotel, and ask to hold the call. Any option/cos/.. that I should pay attention to?

Thanks.

Form 19

Today ... good news! MOH works properly now. What was wrong? amplifier on line wasn't giving 1 watt and was distorted.

Thanks to all of you who helped. Sometimes, simplest things are far to reach, included those duh; but anyway, it's been useful to me to review all steps about MOH. Next time, remember ... power cord is plugged, ... :-) Thanks once again!

This discussion can be marked as 'closed'.

I've always used a toner and a speakerphone/butt-set to off-hook to test MOH on an amphenol. Just thinking out loud.

Toner works great for testing paging equipment too
