RE: How to test IBM Type 1 Cabling...... bigglesnz11 (TechnicalUser) 16 Apr 11 04:24 I used to have a couple of connectors terminated on RJ45 patch cords, then just used an all 4 tester ( @ pairs only) to test continuity RE: How to test IBM Type 1 Cabling......

I haven't heard that ground hum in years.(The impedance for ethernet UTP cabling (described as category 3, 4 or 5 cabling), according to the TIA/EIA-568-A specification for ethernet networks is 100 ohms. The impedance of IBM Cabling System Type 1 cabling is 150 ohms.)I'd recommend:Fluke Omniscanner 2 LAN Cable Analyzer to 300MHz Cat5/5E/6http://www.atecorp.com/equipment/Microtest/Omniscanner.aspYou don't need to test something made by IBM, it tests you. They wrote the IEEE 802.5 specs. KE407122'Who is this guy named Lo Cel and why does he keep paging me?'
