Openreach should have rolled out 100% Huawei cabinets
It is so easy to say that now with the benefit of hindsight.
You do know that ECI were the first manufacturers to make a DSLAM capable of system based vectoring?
Back in 2012 when Openreach were already busy installing the M41's (which had been ordered a year or so previously) who had actually heard of system based vectoring?
G.993.5 was a relatively new invention and previously only worked at line card level. It was complex and wasted ports on the DSLAMS - so vectoring wasn't really a viable option until
ECI manufactured the worlds very first Vectored DSLAMs in 2012.Openreach were not the only SP caught out by the advances in a new technology both Germany and France also ordered M41s - which at the time were actually the preferred DSLAM due to its small footprint and capable of serving more lines
There's an article
here about Australias's NBN rollout of FTTC (which was after Openreach's) which states
at the time of the initial planning for NBN – technologies such as DOCSIS 3.1, VDSL2 Vectoring and G.fast did not exist (except perhaps on paper and in the lab).
So tell me how in 2010/2011 when Openreach were ordering hundreds of M41s they were supposed to have a crystal ball that none of the other SPs had either :/
--------
The problem with the M41's is there is insufficient space on the backplane to install a vectoring unit.
Would a simpler solution be to swap out the M41s with V41s? Same footprint, same linecards. I believe thats what Dueche Telecom did with some of their M41s.
