He then goes on to attribute some network problems to the device
when used in a "high-performance" application.

I would say that we have been using the device in a fairly
"high-performance" application: 4 Sparc 2s chained off of the device.
The length of the thin-wire segment was, however, quite short.
The thin wire segment has now been replaced with twisted pair. 
There has been no important change in the error 
rates observed on machines that migrated from the
thin wire to the twisted pair.

We have been satisfied users of the product.

I guess Richard has a more technical definition of repeater in mind
than I intended - i.e. a device that joins two ethernet segments
at the physical layer, providing signal amplification. I gather
it is a pulse retiming function that Richard feels is missing
to merit this term. By, the way, what ARE the cheaper competing
products that provide retiming? The CTP100T is pretty cheap.

Since this _is_ bc.general I suppose there ought to be some
B.C. general content. So: cold enuff for ya?
