Hi all.

Only just joined this group and hope to have fun as an active member.

I start off with a question/request.

I wish to build a device that will send an ID down a cable (twisted
pair) and be picked up at the far end in order that the cable can be
identified. Now I already use a tone and amplifier which will send a
audio frequency tone down a wire and be picked up at the far end, using
a commercial "Tone/Amp" set from Progressive.

What I what is to be able to attach a series of "tones" or voice ID's to
one end of say a 30 pair telecoms cable and read off which cable is
which at the far side without having to physically switch the device
from one pair to the next, ID'ing say 10-20 pairs at a time.

There is a commercial unit that does what I want called the Voice IDer
from Tempo at
http://www.tempo.textron.com/products/prod_voicetaggers.html

and http://www.tempo.textron.com/archive/ds_voicetaggers.pdf

I want to build this type of device using a PIC ??? although I am
totally new to PICs and their capabilities.

OK now the question. Can anyone help out with a design/circuit or any
ideas as to how it could be designed built programmed?
