Lines: 17 The cable lengths seem to be for real. I've got a 50m cable running from my office to two different DELNI type devices (one's a TCL and the other's a Cabletron). These in turn are connected by 10m cables to their transceivers. Trancevier cable distances are really dependant on what the cable is made out of. We've streched them as far as 100m (it wasn't me who did that, honest) without real problem. I've never found anything in the DEC network book to be wrong. The DEC Network and Communications buyers guide rules on building Ethernet networks are more conservative than what the SPEC's allow and if build by this you shouldn't have any problems. The only complaint I have with spec is that it always specifies DEC parts (natch) and that they always provide the protocol independant solution, which I don't believe in for large networks. -Ron
