Sort of. The problem is at the P50.
1) The P50 has no Leased/Leased setting until now. Current status is that
the feature may appear in Oct97. We need it strong, so we are quite
on the edge here ;)
This makes use of the obvious MPP bundling impossible.
2) SuperDig128
The P50 has SuperDig128, a very mystical feature that is "only available
in Japan". Of cause this is Zen. Actually SuperDig128 seems to be a
straight B1B2B1B2 low level bundling in the S0 frames. This makes it
very easy to handle and performant but also very sensitive to any kind
of asynchronity in the two B channels of such leased lines. Result:
a) It works perfectly with our selfmade lines in lab
b) It doesn't work with the lines provided by our telco (German Telekom).
BTW, you either need to plug a BRI board into the 4000 or get a telco who
can crank 2 B's out of a E1/T1 and plug the line there.
Conclusion: wait for 1 if you don't have the time to tinker with 2...

2 is available a long time (4.6something ?). So nothing special here.
