If you think about it you will realize that it probably is a finite limit
that depends on the traffic on the ethernet. But it is such a large
number that in practical terms you will never reach it. The real question
is how many channels can you bond together. The real limit would depend
on traffic and compression. For precompressed data and 64K isdn it would
be something around 78 channels which would saturate the ethernet on the
box reassemblying the packets. For compressed data it would be less than
that. Since the most you can have in a PM-3 is 60 channels you shouldn't
reach this limit without compression.

Probably hundreds of boxes before you run into problems with that part of
it.
