On the workstation that I am typing this message from I just placed 12 feet of cable between the T-connector and the transceiver on the back of the unit and it is working just fine. All other units on the segment are working fine also. You just have to remember that if you do this the maximum length of your segment will have to be shorter than the maximum length allowed in the specs. We've done a lot of testing/playing with our segments here just to see how far we can push things before screw-ups occur. I've found that the specifications do have a little leeway - you can place cable between T-s and transceivers, you can go directly from thick-wire to thin-wire via N to BNC adaptors, you can use RG-58 cheapo cable with a velocity of propagation less than .77 - it's just that all these things will reduce the maximum allowable lengths of your segments. I'd suggest you experiment with your segment. Try placing cable between the T's and see if it affects performance. We have an Excelan LANalyzer here and I've looked at segments where there are quite a few workstations with cable between the T's and the transceivers, and there were no abnormalities. -- Michael Nora | Internet: mwn@beach.cis.ufl.edu University of Florida | UUCP: ...ihnp4!codas!uflorida!beach.cis.ufl.edu!mwn Data & Video Network | MaBellNet: (904) 335-8300
