nCompatible with IEEE 802.5t

nCopper module uses RJ45 connectors

nFiber module uses SC connectors

nLinks operate independently

nOffer redundant links / load sharing

nEach link can be set to Master or Slave mode

High Speed Token Ring

HSTR Copper and Fiber Modules - 1

As with the Ringswitch HSTR module this only supports 100Mbps full

duplex DTR and is fully compatible with IEEE 802.5t, the HSTR

specification.

There are two HSTR modules:

Copper which uses RJ45 connectors and

Fibre which uses SC connectors

As we saw with the standard TR module, each port is independent

and can be used in the same ways with other HSTR components.
