An active host to terminal connection is called a session. The VT100 Gateway can execute a series of transactions during a session. A transaction is the series of steps required to perform a specific function like finding a customer’s account balance. When one transaction finishes, the session is available to execute another transaction. The Meridian IVR 2.0/I application processor, when configured with the VT100 Gateway product, can control multiple simultaneous sessions with the host computer.

The Meridian IVR 2.0/I VT100 Gateway product allows a Meridian IVR 2.0/I application to establish sessions with a host just as multiple VT100 terminals would. Any programs or commands you can execute from a VT100 terminal, you can execute with Meridian IVR 2.0/I via the VT100 Gateway. Meridian IVR 2.0/I can store host output in the buffers of an application, then play the information to a caller.

The application processor physically connects to the host via a modem if the host is not local, or via a null modem connector if the host resides locally.
