For the system developer, MOST is primarily a protocol definition. It provides the user with a standardized <a href="/wiki/Application_programming_interface" class="mw-redirect" title="Application programming interface">application programming interface</a> (API) to access device functionality. The communication functionality is provided by driver software known as MOST Network Services. MOST Network Services include Basic Layer System Services (layers 3, 4, 5) and Application Socket Services (layer 6).

Its role is to continuously supply the ring with MOST frames. A <a href="/wiki/Preamble_(communication)" class="mw-redirect" title="Preamble (communication)">preamble</a> is sent at the beginning of the frame transfer.

It is separated into 60 physical channels. The user can select and configure the channels into groups of four. MOST25 provides services and methods for the allocation (and deallocation) of physical channels. </p><p>MOST25 supports up to 15 <a href="/wiki/Uncompressed_audio" class="mw-redirect" title="Uncompressed audio">uncompressed</a> stereo audio channels with CD-quality sound or up to 15 <a href="/wiki/MPEG-1" title="MPEG-1">MPEG-1</a> channels for audio and video transfer, each of which uses four physical channels. </p><p>MOST also provides a channel for transferring control information. The system frequency of <a href="/wiki/44.1_kHz" class="mw-redirect" title="44.1 kHz">44.1 kHz</a> allows a bandwidth of 705.6 kbit/s, enabling 2670 control messages per second to be transferred. Limitations restrict the effective data transfer rate to about 10 kB/s (80 kbit/s). Control messages are used to configure MOST devices and configure synchronous and asynchronous data transfer.

The three established channels (control message channel, streaming data channel, packet data channel) of MOST25 remain the same, but the length of the control channel and the sectioning between the synchronous and asynchronous channels are flexible. Although MOST50 is specified to support both optical and electrical physical layers, the available MOST50 Intelligent Network Interface Controllers (INICs) only support electrical data transfer via a three copper conductor configuration; consisting of an <a href="/wiki/Twisted_pair" title="Twisted pair">Unshielded Twisted Pair (UTP)</a> set and a single additional control line. The additional control line is connected to each MOST50 network device in a parallel <i>single shared bus</i> configuration. Each MOST50 device would contain five copper wire connections in this configuration. Control line (for signals sent from the master) and two UTP sets (each containing D+ D−). One set is used for data input (outputted from the preceding device on the network ring) while the other is used for data output to the next device on the ring. As with its fiber counterparts, closing or completing the ring (termination at the originating device) is required for any and all network operation. </p> <div class="mw-heading mw-heading3"><h3 id="MOST150">MOST150</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=MOST_Bus&action=edit&section=5" title="Edit section: MOST150"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>MOST150 was introduced in October 2007.
