About the VT100 Gateway 1-5 Meridian IVR VT100 Gateway Development Guide Product release 2.0/I A Meridian IVR 2.0/I process called the Terminal Resource Server (TRS) controls all VT100 sessions, as well as manages all host connections. The TRS runs as a stand-alone process within the Meridian IVR 2.0/I architecture, and starts when Meridian IVR 2.0[...]

1-6 About the VT100 Gateway 555-9001-316 Standard 1.0 February 1996 ATTENTION! The TRS process for managing calls is restricted to handling one acti ve line at a time (single threaded mode). Therefore, you should add a loop to applications that interact with the TRS so that customers who call at peak hours are informed on the status of their call. [...]

2-1 Meridian IVR VT100 Gateway Development Guide Product release 2.0/I Chapter 2: Template files The TRS process uses action and screen templates to maneuver through the screens of a host application. These templates exchange information with the host application screens and transfer information to and from the TRS’s buffers. Coupled with the VT1[...]

2-2 Template files 555-9001-316 Standard 1.0 February 1996 To develop a voice application that accesses the same information as a terminal operator, you need to tell Meridian IVR 2.0/I how to execute the same series of actions that the terminal operator executes. You provide this information in ASCII files called template files. Template files prov[...]
