Is there a color code backboard standard

[IHeartLowVoltage]

I have seen many different colors of backboards for telco installs. Is there a standard? Someone sent me a link of one company's standards. However, the colors dont look like what I typically see in MPOE/Demarcs. For example the site says Blue is for station cables. However I see blue for the CO blocks all the time.

Some days you are the pigeon, some days you are the statue. Which are you?

What you're seeing is the degradation of standards at the CPE end. That's been going on for a long time, which is sad. I'm not a disgruntled "Bell Head"...just a guy that likes things to be easy.

Used to be that a white backboard was the CO and purple represented the horizonal wiring. I didn't look at the link that franklin97355 posted, but I'm well aware that there are color standards "in the books". Every crazy color from yellow, red and orange has meaning.

Truth is that the telco is no longer responsible for wiring past the demarc (read: inside wiring), and so these "standards" are held rather loosly.

The link that franklin97355 posted shows the old Bell System backboard color coding.
