SM-6T-2-02 APOLLO MISSION SIMULATOR INSTRUCTOR HANDBOOK  1.3.1.11 Up-Data Line Panel.

The purpose of the up-data link panel is three-fold. During nonintegrated operation of the AMS, the instructor is provided a means of inserting up-telemetry information through this panel. The instructor can obtain the up-telemetry infor¬ mation by querying the simulated on-board computer for this data. As a result, the computer reads out the data to be used on the typewriter. In addition, the instructor must also use the up-data link keyboard to inform the on-board com¬ puter as to the identity of the star or landmark that the trainee is currently using for navigation purposes. This function also is implemented in the integrated mode in such a manner as to avoid confliction with trajectory link up-data signals. During the integrated mode, the panel provides the capability to introduce up-data signal faults or inhibit up-telemetry signals. The identity and function of each control and display on the up-data link panel is provided in figure 1-14 and table 1-13.

1.3.1.12 Voice Communications Interference Panel.

The controls located on this panel enable the instructor to insert noise and garble effects into voice transmission by manual control. This effect is limited to one direction only, ground-to-spacecraft. This effect enables the simulation of space communication conditions, distance, antenna position, and spacecraft orientation. The controls are identified in figure 1-15 and the function of each control is described in table 1-14.

1.3.1.13 Console Communications System.

The console communications system (CCS) provides the IO with a variety of voice communication services interconnecting the AMS instructor station with parallel and support organizations in the simulation complex. The CCS consists of a number of independent loops and stations functionally strapped together such that they compose a network for each simulator. The entire CCS is not discussed here except in relation to the AMS operation. The communications circuits for the AMS consist of various talk-listen loops that enable the instructors to interface with major subsystem personnel and intraface with related simulators and training units during integrated operations.

The CCS for the AMS consists of six key-set and six trainer communica¬ tion control stations. Two each of these stations are located at the telemetry console and the remaining four each are mounted at the IOS. Figure 1-16 depicts the key-set stations and their related locations. Each key (switch) provides the IO with a talk-listen capability over the associated loop. The function of each key is tabulated in table 1-15. The trainer communication control stations, illustrated in figure 1-17, provide loop selection for switching, volume controls, and headset jacks. The function of each of the controls depicted in the figure are listed in table 1-16.

1.3.1.14 Malfunction Insertion Unit.

The malfunction insertion unit (MIU) provides control over and monitoring of simulated spacecraft malfunctions. The MIU consists of control and display panels, located on the IOS and T/M console, and the associated electronic logic circuitry. 1-37
