It's even more confusing, as the P50 _can_ bundle in Switched/Switched mode, so the probable guess that they may have a hardware limitation is not true. If they can do it with dynamically assigned B-channels, they sure could do it with statically assigned ones (actually this is a simpler case). IMHO (subjectively ;) the problem they have is that they used a hack to code "SuperDig128" in the NVRAM config. They code it as B1=Nailed Group=1 and B2=Nailed Group=2 (note that these codings are internal, you never have a chance to touch them directly, you always select Switched/Unused or such). Now it _should_ have been Group=1 for both channels. This collides with the meaning I would actually underlay the Group=1,2 setting - the meaning of Leased/Leased so you could either put separate profiles on Group=1 and Group=2 or a Nailed/Mpp profile on Group=1,2 to get 128kbps high level bundling. Then again, may be not. > > 2) SuperDig128 > > The P50 has SuperDig128, a very mystical feature that is "only available > > in Japan". Of cause this is Zen.

There are, however, reports where it did work. We guess in these cases the -T-- used other tech or actually provided a DS02 no D64S2.
