We've an RG-58 network powered by a Cabletron something-or-another, and things are working just fine. Except people have decided to put computers in offices which have no "slack" in the RG-58. Given the following cable layout, what's the longest that strand <foo> can be? Is it just a part of the total distance of the cable?

jet@karazm.math.uh.edu (J. Eric Townsend) asked how long a drop cable can you have from a T connector You should not use ANY drop cable from the T connector to the machine. On a small network it MIGHT work, but I would never try it. What you can do is extend the loop into the room with something like: RG-58 running along a baseboard Barrel connectors ------------------------------------------+ +----------------------- | | | | <-2 short thin coax segments | | T connector ----- Some user's computer. | | | | ----- The only real consideration here is that the thin coax segment is still shorter than 185m. -- Greg German (german@sonne.CSO.UIUC.EDU) (217-333-8293) US Mail: Univ of Illinois, CSO, 1304 W Springfield Ave, Urbana, IL 61801 Office: 129 Digital Computer Lab., Network Design Office

One must also take into account the fact that each of the barrel connectors (and the T connector) counts towards the max of 30 per segment. Bob Currier Network Manager Duke University Durham, N.C. 27706 rdc@bobsun.ac.duke.edu
