Hi everyone, I'm looking to relocate my router as one option to re-organising placement of some gear. I can't move the Telstra stuff as the MDF is in one room and I want to keep Telstra's gear located in the same room. One reason for this is that all the stuff exposed to the unprotected copper from the street cabling can stay with the MDF. A question that's arisen out of this is how far can an ISDN Sbus interface cable run? If I move the router, it'll be located about 20 metres from the Telstra gear instead of in the same cabinet (cable less than half a metre!). Is that going to be a problem? Is there anything wrong with using a shielded cat-5 cable to cover the distance? I don't know if either the Cisco S/T ports or Telstra's ISDN boxes actually do anything with the shield in a standard RJ45 network cable, or even if the wiring is anything like that used for twisted-pair ethernet, but that's what I'm aiming to use. What are the pro's and con's of this approach? Thanks, Craig. -- Craig Dewick (c r a i g @ p o i s o n . l i o s . a p a n a . o r g . a u http://lios.apana.org.au/~craig APANA Sydney Deputy Regional Co-ordinator.
