We have a number of the AT&T Starlan 10 hubs.  They work fine, but
were only current at Draft 7 (if memory serves) therefore do not have
the link integrity test function.

We have looked at the more modular products, such as the Cabletron MMAC
and similar products from other vendors, but the economics aren't there
unless you really want enough smarts to run SNMP.  For a reasonably
typical Starlan installation in the College of Nursing, we have several
hubs cascaded together - plus the 15 pin port on one hub has a thinnet
transceiver supporting some machines which have only thinnet interfaces,
and the 15 pin port on the other Starlan hub has a fiber optic transceiver
supporting the link to the router in another building.  This gives us
the flexibility we need at a lower cost than the MMAC and competitors
(but admittedly with no SNMP support).
