Madge Networks Token Ring Switch

Smart DeskStream Technical Presentation 12

nSmart DeskStream is NOT designed as a

backbone applications switch

nYou can only support a shared device on one port

nIt does NOT offer Active Broadcast Control, full

RMON or protocol filtering.

lThese are backbone features, not required at the

workgroup level

nSmart Ringswitch Family is for backbone

solutions

nDeskStreams and Ringswitches can be integrated

to provide a TR switching solution

Smart DeskStream

Background Positioning

As we saw in the slides on integrating into an existing network, the

DeskStream has only one workstation port which is capable of being

connected to a shared medium hub.

Uplink ports can be connected to CAUs either as nodes or ,if using

fibre, as RI/RO ports. This connectivity option is not recommended.
