BOCAHUB-24Plus
Functional Description
The BOCAHUB-24 Plus is an implementation of an
IEEE 802.3/Ethernet repeater or hub. It provides 24
10BASE-T ports, one 10BASE2 port, one AUI port, and
one expansion port in a single hub. The BOCAHUB-24
Plus complies with the full set of repeater basic functions
as defined in section 9 of ISO 8802.3 (ANSI/IEEE 802.3).
These functions are defined below:
Repeater Function
If any single network port senses the start of a valid
packet on its receive lines, then the BOCAHUB-24
Plus will re-transmit the received data to all other
enabled network ports.
Signal Regeneration
When re-transmitting a packet, the BOCAHUB-24
Plus ensures that the outgoing packet complies with
the 802.3 specification in terms of preamble structure,
voltage amplitude, and timing characteristics.
Jabber Lockup Protection
The BOCAHUB-24 Plus implements a built-in jabber
protection scheme to ensure that the network is not
disabled due to the transmission of excessively long
data packets.
Collision Handling
The BOCAHUB-24 Plus will detect and respond to
collision conditions as specified in 802.3. It will also
