Ben, Thanks it mirrors much of my own experience- in your scenario - are the same vendors using different chipsets in the DSLAM versus CPE?

I can also say that VDSL2 performance varies wildly depending on chipset and how you mix manufacturers. I have great examples of where you get better sync rates mixing vendor DSLAMs and CPEs as opposed to same vendor at both ends of the link. Regards... Ben On 30 October 2013 18:16, Neil J.

Haroldo, Do you see any noticeable difference in sync performance? One of the concerns raised by some of my colleagues about doing a wires free service is the requirements in compatibility between chipset vendors, and personally speaking in the past (with Cisco 8xx specifically) on ADSL2/2+ was pretty challenging with different chipsets in different CPE/DSLAMS. Also need to ensure future chipset compliance with a potential vectoring roll out.
