Could someone provide me with a response the following question from a
customer?
>>Can you tell me with which vendors DEC's FDDI concentrator copper
>>interface is compatible?
Thanks in advance,

There are two parts to this answer. The first is that DEC's Thinwire
is only compatible with DEC.
The STP interface is compatible with anything that implements the
"Gang of Five" specification. Note this is not the "SDDI" specification
supported by IBM. I don't have a current list of vendors supporting
that spec which, of course, is what you really need.

| 851.2 | STP standard = ThinWire? | ISKATE::BILLD | Mon Aug 09 1993 17:29 | 5 | |
Does the STP standard apply to ThinWire, as was emplied in the previous reply? Bill D. | |||||
| 851.3 | STP,Gang 'o Five, Thinwire != standard-based | LEVERS::MELARAGNI | Mon Aug 09 1993 20:22 | 13 | |
No, absolutely not. Both the Gang of Five, STP, and Thinwire
implementations are PROPRIETARY in that no standard exists that supports
any of them. I've heard tell that IBM is (was) trying to create an
ANSI-based standard for their STP stuff, but it think that has all but
died in the face of TP-PMD.
Gang of Five and STP are quite similar but have some subtle
differences. Thinwire is completely different that any other media
implementation (it uses only one cable for bidirectional communication
using echo cancelation). As far as i know DEC is the only producer of a
Thinwire PMD.

| 851.4 | Final Question.... | ISKATE::BILLD | Thu Aug 12 1993 11:51 | 5 | |
For a final question: Is there a standard being worked on for a ThinWire implementation as there is for UTP and STP? Bill | |||||
