I need a device that will simulate 2 phone lines for the purpose of testing
data communications equipment.  Ideally, it would provide dial tone, and
when dialing was detected, ring the other line.  I could also use a simpler
unit that would provide dial tone and ring voltage under manual control.
This latter I could build, and will if I can't find something ready-made.
For that, I need to know what the frequencies of a standard dial tone are,
and where I can get a 100V 20Hz ring supply.

Thanks,

Steven Gaarder
