Rmi System Installation; Figure 1. Unduplicated Rmi System (Phase 1) Block Diagram - AT&T System 85 Installation And Test

RMI SYSTEM INSTALLATION
This section contains instructions for installing RMI hardware in an unduplicated and
duplicated system. Figures 1 and 2 are basic block diagrams showing the connections
necessary to add Phase 1 RMI to an existing unduplicated or duplicated System 85. Figures
3 and 4 are basic block diagrams showing the connections necessary to add Phase 2 RMI to
an existing unduplicated or duplicated system. The duplicated systems shown in Figures 2
and 4 are for fully duplicated control functions (common control, module control, and Time-
Multiplexed Switch [TMS]). It is possible to have other combinations of duplication. The
actual connections for these configurations are shown later in this manual.
