Programmable
Dial-Number Blocking Device: |
 |
Hardware
and software design of device, built
around AT89C52, prevents such connections
being made by barring up to ten freely
programmable numbers or number prefixes.Thus,
for example, not only can 95-prefix
numbers can be blocked, so can others
to allow only local calls, to bar
international calls, to prevent carrier
selection prefixes, and so on.
