A communication system, network, interface, and port architecture are
provided for transporting different types of data across a network. The
network can be arranged by connecting the ports in a daisy chain fashion
to achieve a ring architecture or topology. The network forwards data
according to a specific network protocol, and any incoming data that
follows that protocol will be sent onto the network. If the incoming data
protocol does not match the network protocol, then the incoming data is
not sent immediately to the network, but instead is sent to an input pin
of a device upon the network specifically designed to receive that
incoming data. The network, therefore, has ports that support both
compliant and non-compliant incoming data, and the devices that produce
such data. Examples of non-compliant data include any data which does not
time-division multiplex different asynchronous, isochronous, and
synchronous data in dedicated channels within each frame, and which have
a preamble, coding, frequency, or overall protocol different from that
which is established for network transfer.
