Remote Console; Introduction - AT&T System 85 Installation And Test

REMOTE CONSOLE
Introduction
A remote console is available for use with systems equipped with Remote Modules. This
feature requires connections at both the remote and central locations. In addition to the
connections required at the remote location, the connections unique to the remote console at
the central location are contained in this manual. The connections at the central location
that are not unique to remote console are contained in AT&T System 85 Installation (555-
103-104). A block diagram of the Remote Console connection is shown in Figure 61.
This feature uses the 107A Optically Remoted Peripheral Interface (ORPI) in a fiber-optic
link subsystem in combination with the TMS and RMI links to provide attendant console
service for one or more remote System 85 modules. The ORPI unit is intended to function in
pairs, one located at the central location and the other at the remote location. The ORPI has
the capability to serve a maximum of five consoles. The ORPI should be mounted adjacent
to or near the cross-connect field since the ORPI requirements of data, voice and control,
alarm and power come from the System 85 via the cross-connect field.
