From Cabletron Systems literature:

		V1.0		V2.0			IEEE 802.3
------------------------------------------------------------------------------
Transceiver	(3)22 AWG pairs	(4)20 AWG pairs		(4)20 AWG pairs
Cable		pairs		Inner & Outer shield	Inner & Outer shield
		(1)20 AWG	common at backshell	isolated from each
		Inner & Outer	and pin 1		other
		shield common				Other shield at
		at backshell				backshell inside
		and pin 1				at pin 4
							Indented Male
							connector for better
							electrical connection
------------------------------------------------------------------------------

If I see, on the male end of cable, pin 4, I assume it IEEE 802.3
transceiver cable. Otherwise, I assume version 1 or 2 cable. I use a
Cabletron LAN-MD if I not sure and I want to test the cable integrity
without opening the hoods.

No, I do not work for Cabletron but a satisfied customer.
