 USOC vs. WECO
Hi,
I was wondering what the difference is when you use a USOC standard on one end of a cable and WECO standard on the other end? I know whe pinout changes, but is there anything else (performance, crosstalk, etc.)?

Dear Ben,

Performance (from a standards point of view) can only be done if the cable is installed and wired to either the T568A or T568B wiring standard. T568B is the same as WECO. If you wired to a USOC standard then you don't have the same pairing combinations which will mean disaster for data application since a balanced pair on designAted pins is the basis for the design.

Sincerely,
Joseph Golan, RCDD
