TIA 568A
TIA 568B
It is important that the correct pairing is observed. Transmit, Receive, and Mic
need to be on twisted pairs. Splitting pairs (e.g., using a white/green wire with a blue/
white wire for transmit) will result in increased crosstalk, and may result in bus failure
or noise on the intercom.
