New Phone - Premier ASH 2500

[dc4code]

Hey, Guys, my grandma found an old phone at work and she gave it to me,

It says on the back '04-98' so I'm assuming it was made in April of '98 but that's not really old.

I opened it up and I saw on the back of the keypad I see a microchip I believe it is a Multiplexer of some sort.
You guys know on the old touch-tone model 2500s from the 80s and late 70s that once you press 2 keys at once you here that weird tone? It doesn't work on this one I'm assuming its because this one has a microchip and the older ones do not.


It is a premier ASH 2500

If anyone wants a picture of the inside of the phone just let me know, I'm not at my house but I found this picture that's exactly the one I have.

You are correct, those did not use two coils to produce the multiplex tone, like the older dials did. So pushing two buttons at the same time does not produce the "wired tone"
In fact it will produce a single digit tone by cancelling out the second digit that was pressed.
And yes touch tones are produced by the chip along with other components on the back of the dial.
And actually subtract 6 months from the date printed on the bottom of the set. They dated them six months in advance of actual mfr date.

Look like my phone was actually made in October of 1997 in that case

Why would they date them in advance? Was  that how long they estimated they would sit as stock before entering field service?

It's what Cortelco did. They figured it would take about six months to stock and sell the phones. At least that's what I was told by someone else who knew someone who worked at the plant.

Could have been for warranty purposes - with these being purchased in bulk, keeping track of receipts and "which phone was ordered when" is almost impossible in large installations.  Make sense?
