DTMF Decode and Paging Controller

So, you need a "simple" solution that allows you to use a DTMF decoder to page to 8 output zones.

Here is one with four different channels of BGM source material and a page input that would theoretically be connected to the "Page Port" of a telephone system. This is an "inexpensive" solution to "How do we control paging?" The answer is "With the telephone system." Everyone already has a telephone on their desk, give them a list of paging codes, set up those paging codes in this device, and whomever dials the page port can page to their zone accordingly.

This solution is easy to use for the end users, so it will be a bit complex to set up initially.

I built this for our distributor in Canada.
