Question : Problem: Cat 5e cabling - Does using a 66 block violate the standard?

I am troubleshooting problems at a location that has cable locations terminated with a 66 block?
I know this was commonly used with Cat3 cable. I thought it was discontinued with Cat5e. Since the cable is untwisted when installed on the 66 block, is it possible that the block is causing errors that might be solved by terminating to a patch panel or wall jacks? If so, where can I find this in writing to quote to my customer?

Thanks in advance for your help.
Bob

THE official document is from the TIA/EIA - TIA/EIA-854.  To obtain it will cost you, $100.00 USD.
