No, there was no ALE involved.
There are Alcatel systems around that do this.
Personally I'd like to separate the radiomode and it's use, I should be
able to
use whatever mode with whatever protocol I like. I'd like to see this
as a toolbox
where I may for instance use the same protocol and switch to a radiomode
which suits the current conditions. If conditions get bad and MFSK
still works but
FSK fails with ax.25 then I'd like to use MFSK with ax.25, when MFSK
fails then
I'd like to use some psk-form if that's any better etc. The link layer
model should
be put to better use.
MIL-STD-188-110A is a bad example but is anyway capable of adapting the
psk-mode, speed and interleaver size to the incoming data. If I realize
that I
get fast fading on the receiver side then I may change to short
interleave on
the transmitter side. When conditions improve I may increase the speed
(9600 bps maximum).
But never mind me, ten years of military traffic has clearly affected me
;-).
I've heard quite a number of MFSK stations on 20 mtrs now so I had
better get
a few QSO's.
