In response to the Starlan-10 and 10baseT.

It is my understanding that HP's Starlan-10 and UB's Access/one
was a joint development. I have the twisted pair adapters for both
and they look identical (inside and out) except for the LOGO.
I haven't seen AT&T's starlan but it is my understanding it is
the same as HP's.

It is my understanding (from a presentation from UB) that the proper
way to test twisted pairs for these networks is to plug a TPAU
(twisted pair access unit) on each end of the pairs, and then to
use a "standard" (perhaps regular is more appropriate) Ethernet
tester and run a test as though it was an Ethernet.

I personally took this a little further and decided since a tester
thought it was an Ethernet, why not use it as an Ethernet ? Well it
worked. I put a multiport transceiver in each of two buildings which
are connected through TPAU's to each other through 900 ft of telephone
wire. This is a judgment call kind of network, not to any known
standards, but it is fitting the needs of the user.
