Jacks are designed to work only with solid ethernet cable. Most jacks come labeled with color coded wiring diagrams for either TA, TB or both.
Make sure. Then when looking at wiring diagrams for TA vs B I noticed my jacks wiring diagram was significantly different from anything I was seeing.
All or part of your cabling system has been installed with TA-wired jacks on one 2 and 3 are reversed (B) to reconfigure wiring to TA-to-TA scheme. These wiring schemes include TA, TB, crossover (flipped), cord wiring scheme if they cut the patch cord to terminate a jack module on one end.
TA and TB are the two color codes used for wiring eight-position RJ45 ATA&T A color code and is/was(?) the most widely used wiring scheme.The first revision of the standard, TIA/EIAA was released in The standard was updated to revision B in The demands placed upon commercial wiring systems increased dramatically over this period due to the adoption of personal computers and data communication networks and advances in those. TA and TB are the two color codes used for wiring eight-position RJ45 modular plugs.
Both are allowed under the ANSI/TIA/EIA wiring standards. The only difference between the two color codes is that the orange and green pairs are interchanged.
Based on TIA/EIAB, the TA and TB wiring schemes define the pinout, or order of connections, for wires in eight-pin modular connector plugs and jacks. The only difference between TA and TB is that pairs 2 and 3 (orange and green) are swapped.
The main similarity between TA and TB is that they both provide wiring schemes for terminating twisted-pair copper network cable to 8-position RJ45 jacks and connectors. “8 position” refers to the fact that RJ45 data transmission requires 8 conductors, which are provided by the 4 twisted wire pairs found in the copper-based network.
