Sorry Sam, but I don't understand what you mean by "isolation".

Also, what do you mean by the "bud" of an earphone jack? The plug? And hook it up where?

Sorry for all the questions, but I'm really green in this area.

OK, I think by "bud" you mean the earpiece (sorry, I only speak Canadian ) OK, no problem, but where do I connect the wires?

OK, ED answered my question in this thread:

MOH

"With the LC400E, only one line card in the system can have music on hold. If you connect the same music source to more than one card, callers will be able to talk to each other while on hold, something I am sure that you DON'T want. In order to isolate them, you'll need an ITT K403 MOH card in a separate mounting, which is all but impossible to locate anymore.

If you only need MOH on one card, you'll need to connect the music source to pins 3 and 18 of the card slot itself. This means that you'll need to unwrap the existing wires on the pins, then insulate and store them. Connect your music source to these same pins and you'll be all set. Be sure to keep the volume low at first because if it's set too high, you will blow out the input transformer on the LC400E card."

Will this work on a 400D card?

I don't think so. I don't think that a 400D had contacts on pins 3 & 18. If you need a 400 E (or similar) speak up. I'm sure someone can dig one up.

And I'm compelled to ask. What does your signature say? (Please don't say "It's all Greek to me")

Sam

Morning SS!

Surprisingly, I actually have a 400E card. Bought it on the bay of E. If I could get my hands on two more, that would be great!

My signature line says (it's in ancient Greek actually) "If you're not a philosopher, you're not a Greek"

Well, the other two won't help you unless you get an isolation card.

Sam

I can provide ITT K400E line cards, as well as a K403 MOH card and also the seperate mounting enclosure. Let me know if you're interested. Here's some pics of the enclosure, I'm not sure if it's what Ed is referring to or not....

I can also provide a SAN/BAR MOH tuner card, or an external VALCOM FM tuner if you're interested.

If it all looks like what everyone thinks ya need, pls PM me for further info -

Thx
Matt

I know Sam, but since I already have two lines, and am considering a third, I think I might go for the isolation card.

Quick question(s):

Pins 3 and 18, is that numbered from top down or bottom up?

Does it make a difference which wire I attach to the pins? I mean like, left ear bud to 3, etc?

D'oh! They're numbered. :rolleyes:
