When re-transmitting a packet, the BocaNET-24 ensures that
the outgoing packet complies with the 802.3 specification in
terms of preamble structure, voltage amplitude, and timing
characteristics.

The BocaNET-24 implements a built-in jabber protection
scheme to ensure that the network is not disabled due to the
transmission of excessively long data packets.

The BocaNET-24 will detect and respond to collision
conditions as specified in 802.3. It will also protect the
network from excessive collisions by “partitioning” the
offending port from the rest of the network. Once a port is
partitioned, the data received from that port will not be
repeated. However, any other data on the network will be re-
transmitted on that port. If the collisions that cause the
partitioning cease, the port will be re-connected to the rest of
the network.
The status of the partitioning scheme can be checked at any
time by observing the bi-color LINK/PRT LED on the front
of the BocaNET-24. If any ports are currently partitioned, the
corresponding LED will be RED
