Hi Tom,
I did not receive copies of any specs but our distributor did send me
the basic parameters required for modems, some of which answer your
questions.
1. Loop current for testing = 17 - 55 mAdc, resistance presented to
the line < 600 ohms.
2. ring sensitivity: > 40Vac, ring insensitivity: < 16 Vac; 25 & 50 Hz
3. [no dial tone information]
4. dial line: Rx = 0 to -43dBm, Tx = 0 to -15dBm adjustable; both with
respect to 600 ohms.
5. [no leased line information]
Sorry I could not be of more help.
Good luck,
Jack
