This may be a naive question but is it permissable to connect one ethernet AUI cable from an ethernet device into another instead of connecting each to a cable tap and have these tapped into an ethernet cable. I want to plug a bridge into a repeater. I know that an ethernet device provides power for a cable tap so I suppose there could be some confusion if two devices were supplying power to each other. If this is not permissable is there any other way around this as it seems that you have to have a lot of redundant equipment to achieve this connection when the two devices are sitting next to each other.

Unfortunately, no. The signals on the AUI cable are not symmetrical; you need electronics in between. Usually the cheapest way to do this is to use a multi-port transceiver/AUI, as most of them can be configured so that they don't need to actually connect to an Ethernet cable. -- SVR4: every feature you ever | Henry Spencer at U of Toronto Zoology wanted, and plenty you didn't.| uunet!attcan!utzoo!henry henry@zoo.toronto.edu

Standard disclaimer: I am not affiliated with but am a satisfied (small) customer of the ANC division of Netcor. Try the ANC-10 AUI-to-AUI adapter. Takes power from one side, has nice diagnostic LEDs. Can't just make a "null-transceiver cable", because of collision detection logic. An ethernet subscriber has to be able to hear itself, approximately speaking. -- Don Doerner dd@ariel.unm.edu University of New Mexico CIRT 2701 Campus Blvd, NE Albuquerque, NM, 87131 (505) 277-8036
