ITU Modem T-288 Series
 
How do I setup modems for a leased line connection under Windows NT 4.0?

When two modems are connected via a leased line, it is similar to connecting 2 PCs by a cross-over cable. These two machines are transparent to the PCs, so you don't have to have a modem driver.
Steps: Settings for the MODEM:
1. Load the factory profile (default settings) for "leased line" connection (#3, #4 for 2WLL; #7, #8 for 4WLL).
2. Change Protocol: "Protocol"->"Protocol Type" to "Auto MNP/V42".
3. Set Data format: "Config DTE"->"Data Format"->"Async"
4. Set flow control: "Config DTE"->"Flow Control"->"RTS/CTS"
5. Set DTE speed: "Config DTE"->"DTE Speed"->"38400"(assuming you have set your RAS to 38400)
6. Settings on NT: Install modem by adding "Dial-Up Networking Serial Cable between 2PCs" in the Standard Modem menu.
7. Setup this null-modem to "Dial-out" and set RAS speed to match the DTE speed of the modem.
8. Dial from "Dial-Up networking" to connect to a remote modem.
