Reading a bio of Claude Shannon and it crystallized a sense I have of how engineering culture has changed into tech culture. Shannon embodies a certain ethos that used to be everywhere, where the goal was to do really smart stuff, and spend your spare time on unicycles and flamethrowing trumpets.

CAMEL had always been one of those weird #3GPP protocols that was hard for me to find info on or play with, I had a chance to work with it last year and get familiar with CAMEL, so here's the basics of CAMEL charging flows:

There would be some deep irony in them having to pay the RBS levy to overbuild the FWA footprint with fibre, to fund the NBN FWA network they're making redundant in the areas they'd target.
