Hi
i have a trouble with my project. Can you help me wiht
your ideas?
If subscriber dials 0 this circuit must add some
digits between zero and other dialed numbers.
ex: 0(89256)555*******
subscriber dials only 0555****
I'm planning to use Holtek ht9170(receiver),ht9200
But; i couldn't figure out how to fix my circuit to
the phone network. a relay may be help me if it is,
how.
Thanks...

Hi,
I have a trouble with my project. Can you help me
with your ideas?
If subscriber dials 0 first,my circuit must dial some
digits automaticly after zero. Then the other numbers
which subscriber has dialed must be added, after that
circuit must be by-passed to the telephone line.
ex:0(8799676)555****
If subscriber dials another number circuit must be
by-passed to the telephone line.
I'm planning to use HOLTEK HT9200,HT9170 and a pic.
However, i could not figure out how to fix my circuit
to the telephone line and how to by-pass (a relay i
thing)it. So i am waiting for your help
Thanks....

You can only make this with a redialer.
I mean: the user dials over YOUR simulated line, and your systems
dials over the real line.
and later, your system conects the user's phone to the real line. This
is basically what a phone central does, and involves matrix switcher,
tone generator, etc.
I did something like this some time ago, but with shorters numbers:
- when suscribers dials #19,
- the system hook-on the comunication (terminating comunication),
- delay 1seg (to bee sure the comunication is over
- hook-off again (taking line)
dials 0800 xxxx (number stored in EEPROM)
So I didn't need to simulate the line and make a two phone lines to
connect at same momment.
Whe users dials a number that wasn't in the table of 'fast dials', it
simple does nothing.
It's not easy to make....
Good luck!
