−
−	~~The H4000 Ethernet Transceiver with Inclusive Tap was the very first [[Ethernet]] Transceiver from DEC.~~
−
−	~~It has got two drawbacks:~~
−	* If the tap gets damaged, the whole unit is inoperable and cannot be repaired.
−	* It is very inconvenient to mount the unit to a Thickwire segment difficult to access, e.g. located in a ceiling plenum.

−	~~The H4000 Ethernet Transceiver with Removable Tap is an improved version of the model with a fixed tap.~~
−
−	~~You can tap the cable using the removable tapping unit (which is much smaller and lighter than the complete unit) and attach the rest of the unit when the tapping is done.~~
