|Product CN-8312 - 1 port CN-3000 Compatible to connect to a CodeStar Passive Hub, ST/SMA
The CodeNet-8310/8312 MultiStar Module allows the user to
directly link a passive fiber optic network segment to a Codenell MultiStar/3Com MultiConnect Ethernet active star. The
Codenet-8310/8312 is completely compatible with IEEE
802.3 hardware and software and is plug-in-compatible with
the MultiStar Repeater. The Codenet-8312 is also backward
compatible with earlier Codenell fiber optic products.
The CodeNet-8310/8312 MultiStar Module provides for direct
interfacing between an individual fiber optic network segment
and a MultiStar Repeater, The 8310/8312 Module contains an
integrated fiber optic transceiver which eliminates the need for
separate fiber optic transceivers.
The CodeNet-8310/8312 Fiber Optic Repeater Module also
contains front panel status indicators and manual reset/partition controls for quick diagnosis and resolution of network
The CodeNet-8310/8312 is used with a CodeStar passive
fiber optic star (which constitutes an optical segment). The
CodeNet-8310/8312 includes built-in collision detection, and
a fiber break feature for improved network reliability and performance. Once a fiber break has been detected, the CodeNet-8310/8312 automatically partitions itself from the rest of the
segments and when the problem has been resolved it will automatically reconnect the fiber segment.
The CodeNet-8310/8312 also contains a switch selectable
test circuit, which allows it to be used as a light source for network testing of the fiber optic cabling. The CodeNet 8310/8312
Module is also capable of asserting the "Jabber" function when
a faulty controller is detected. The unit will automatically partition itself from the error-free segments and will automatically
reconnect when a fault condition no longer exists.
When a segment is auto-partitioned, its partition LED glows
continuously. Once a segment is autopartitioned, the segment
is sampled every 400 msec by transmitting a 523 bit packet
called a "bleep." if the "bleep" packet is transmitted success
fully without a collision, the segment is reconnected. The partition LED then begins flashing, indicating that the problem has
been resolved. The reset switch on the front panel clears the
LED and does not affect the segment's operation.
