whether a specified port on a module is connected to another
MSH (Inter-repeater Link) or to an end-station.
You will find further information in the user guides that
accompany Repeater Modules.
4 Port Ethernet Bridge
The 4 port bridge module connects the three Ethernet busses of
the MSH backplane and an external port which is provided
through a transceiver module. Various transceiver modules are
available, giving you a choice from the media on your network.
The 4 port bridge module offers, in addition to transparent
bridging according to IEEE 802.1 Part D, custom filtering and
spanning tree algorithm and protocol (STAP).
LEDs indicate bridge activity and give diagnostic information.
Ethernet Transceiver Modules
A number of plug-in Ethernet transceiver modules are available
for some Ethernet modules. These transceivers provide network
connections to different media and are the same as those
available for the ECS and other 3Com products.
For example, fiber optic transceiver modules can be installed on a
variant of the MSH 10Base-T module, allowing an o ptical fiber
backbone to be established.
