3.1.7 Menu LED Indicators
Each Menu LED corresponds to the MODEM group or SWITCH group key located to the right of the
LED. When lit, these LEDs indicate which menu tree is currently active on the LCD. For example,
if the SWITCH-TEST LED is illuminated, then the LCD is displaying one of the menus that allow
control of RCS10 test modes.
3.1.7.1 SWITCH STATUS LED Indicators (Color as indicated below)
Normal: Green - indicates that the unit is currently under power
Major Alarm: Red - indicates that at least one satellite channel did not receive redundancy
protection and is off-line.
Minor Alarm: Yellow - indicates that a redundancy warning exists and the RCS10 may not be
providing redundancy protection.
Test Mode: Yellow - indicates that the switch is performing one of the system tests.
Event: Yellow - indicates that a condition or system event has occurred that the RCS10
has stored in memory. The events may be viewed from the Front Panel
or from the Terminal port.
Remote: Green - indicates that the unit is set to respond from either the Terminal port or
the Remote M&C port
3.1.8 Local/Remote Control
The switch operates in both Local and Remote modes. In Local mode, changes to the system’s
configuration can be implemented only from the RCS10 front panel. Remote access to the system
is limited to a query of status information only. While in the local mode, the switch responds to
remote commands with the Error Message ‘Not Allowed in Local Mode.”
In Remote Mode, configuration commands can be issued from a ‘Dumb’ terminal, a computer, or a
network through the system’s built-in Ethernet channel. The terminal and computer interfaces to
the switch are mutually exclusive. In Remote mode, all front panel switches used to change
operating parameters are locked out and changes can only be made remotely. LEDs and displays
remain operational, however.
The only configuration command allowed into the system, whether it is in Local or Remote mode, is
a change in Control mode. The user can command the system to go into local or remote modes
from the front panel, dumb terminal, computer M&C or a network.
3.1.9 Terminal Control
The switch will emulate a WYSE-50, ADDS-VP or VT-100 dumb terminal. It will display a Main
Menu and prompt the user to select the equipment to monitor and control. If the system is in
Remote mode, configuration parameters can be altered. If the system is in Local mode, however,
no commands are allowed except for a control mode change.
Terminal mode has several basic display screens that show the current status of the RCS10’s
modes and variables. The screens will show both status and control variables. Only the Control
variables can be modified. To modify a variable, the user will enter the variable number at the
prompt followed by a carriage return. The cursor then will move to the variable area and the user will
either type in a new value or press the space bar to scroll through the available selections.
3.1.10 Remote M&C Interface
The interface to a remote computer and monitor system is done through the Radyne ComStream
RLLP protocol. There are two types of packets the switch can receive; Direct and Encapsulated.
Direct packets are those intended for the switch, and Encapsulated packets are those intended for
the modem or the UIMs. The Encapsulated packets are embedded in the switch’s relay command.
