The racal/vadic ACU interface is provided by the files

which monitors the file, simulating a standard DN dialer.
To place an outgoing call one forks a sub-process
and then opens the corresponding file

recording accounting information for later use.
The codes for the phone numbers are the same as in the DN interface:
