There used to be quite substantial usage of X.25 in Brazil, for a lot =
longer than usual, for POS transactions. x.28 in fact, that would be PAD =
to X.25, may still be the case ? (RENPAC and 3028 come to mind)
The management of some Nortel GSM devices also could be done over X.25, =
usually, it would be backhauled over XOT (or in this case, the Nortel =
equivalent) to the management station, from the devices (I'm happy to =
say, I don't remember if from the BSCs, or BTSs).
Of course, QLLC and running QLLC to LLC (token ring) devices, was the =
cherry on top..SNA on top of X.25, converting to token ring SNA..
Somehow, I can't get rid of the nightmares and the waking in the middle =
of the night, thinking about LAPB, and Clear codes and etc., LUs and =
PUs...the horror...the horror..
