Sequence of MOST components

Component Identification:

MOST (Media Oriented System Transport)
The MOST is a fiber optical cable-based networking system that utilizes the capability of optical information transmission. The data are transferred using light pulses. These are transferred to the components connected to the MOST ring (e.g. CD changer).
The light pulses are then converted into electrical signals in the receiving component.

Because of its fast transfer rate the MOST ring can transfer source data (music and voice, etc.) and control data (commands, etc.) simultaneously without affecting the information content. This reduces the quantity of wiring considerably.
The connected components therefore only require 2 lines for the voltage supply, 2 lines (input/output) for the fiber optical cable of the MOST and 1 line for the wake-up signal.

Data transmission using fiber optical cable has the following advantages:
^ Extremely high data transmission rate
^ Prevents tapping and cross-talk
^ Data transmission is not sensitive to electromagnetic radiation
^ Short-circuit resistance
^ Floating connection to the MOST ring subscribers
^ No oxidation
^ Low weight of fiber optical cable
^ Small line diameter

The MOST has an enclosed ring structure. The components are arranged in a ring line (series circuit). This arrangement is adapted according to the series.
The information is transmitted in one direction only, in other words the light pulses for the microphone array control unit run through all the components connected to the MOST ring.

The COMAND operating, display and control unit plays a major part within the ring structure of the MOST ring. All the components connected to the MOST ring can be controlled from here.

When the system is first put into operation, a system test is performed. During the test, the individual components and their sequence in the ring structure of the MOST are recorded by the audio gateway and compared to the source and control data of the equipment-specific sequence of the factory-stored data. With the assistance of the STAR DIAGNOSIS the components in the audio gateway can be re-coded (e g. variant coding).

The MOST ring can be diagnosed via the audio gateway.
