TSB- -155 Mitigation 155 Mitigation TSB Mitigation is one strategy to reduce alien Mitigation is one strategy to reduce alien crosstalk coupling for existing category 6 crosstalk coupling for existing category 6 cabling plant. Mitigation includes: cabling plant. Mitigation includes: • Unbundling cables and cords Unbundling cables and cords • • Interconnect vs. cross Interconnect vs. cross- -connect connect • • Use of long length cords Use of long length cords • • Use of augmented category 6 components Use of augmented category 6 components • • All of the above All of the above • • See TR42.7 See TR42.7- -05 05- -01 01- -013 013- -NEXTMitandTest NEXTMitandTest. .pdf pdf • January 2005 IEEE 802.3
