cabinet upgrade?
« on: December 03, 2019, 02:06:01 AM »

Hi folks, long time no post!

I noticed that our net went down, the line stil had power but the vdsl side reported no power, anyway about 20 mins later it came back up and everything looked normal at first glance then i noticed that the vendor ID had changed..

It went from this

to this..

My question is, is this a cab upgrade or a software one. if its a software one, does anyone know what the improvements are?

I also wonder if its related to FTTP which is currently underway near me (based on the works reported by one.network), the csw site reckons about May next year.

Cheers

Definitely nothing to do with FTTP.

It's actually the DSLAM line card version/firmware that is reported.

Highly likely an expansion was added to the DSLAM.
Simply larger line cards.
