Appreciate the info, even if it is a bit of a killjoyThat's a VDSL Sidepod.
It contains a Huawei MA5818 DSLAM and can hold 4 x 64 port VDSL2 line cards.
They appear on codelook as "VDSL Sidepod" when live.
They no longer install 2nd DSLAM's (or 3rd, i know of a couple PCP's with 3 DSLAM's) but use these sidepods instead.
There are now thousands of these in the network.
As the articles on ISPReview point out, there has been no new G.Fast areas announced since... 2018?
Not a single G.Fast pod has been installed since the end of 2019.
They use the same identical exterior pods they used for G.Fast for VDSL expansion and for Subtended Head-Ends.
Thinkbroadband have images of a Nokia S.H.E in 1 of these pods on a PCP.
