IIB Hardware Reference Introduction
CTI Products, Inc.

1. Introduction

The Input/Output Interface Module (IIB) is a member of the Monitoring and
Control Network (MCN™) family of User Interface Modules. Hardware
specifications, special installation, and configuration information are described in
this manual.

The IIB module connects a parallel operator display device (such as a console) to
the MCN network. The IIB is used with the operator display device and a
Comparator I/O Module (such as a CIB or AIB) to create a comparator display
system. The comparator display system provides monitoring and control functions
for your communications system. Receiver states monitored by the IIB include
VOTE, RECEIVE, DISABLE and FAIL. Receiver functions that can be
controlled include FORCE VOTE and DISABLE.
