3. Test Your Site Modem's Setup
Never leave the site without testing your PC and site modem setup. This will
require a second modem (supporting V.42 error correction and a minimum of 9600
baud) and another available ASTU port, outside line or dial tone source. Testing
ensures the modems can communicate properly and the system will properly release
a connection.
To test the modem setup:
1. Plug one end of a modular line cord into the LINE jack on the back of the sec-
ond modem.
2. Plug the other end of the modular line cord into a modular jack connected to a
different ASTU port or dial tone source.
3. Connect the modem's power supply and turn the unit on.
4. From the PC connected to the second modem, follow the procedures in Part 4,
