ICIM Introduction
ICIM Function
The ICIM functions as the module-user interface as well as the interface between the
Prisma II modules and the Transmission Networks Control Systems (TNCS). The
ICIM allows local module configuration and status monitoring for up to 82 modules
located in multiple chassis. The ICIM features easy-to-use software that is navigated
using the numeric keypad and the LCD display.
