Slightly off the original question, but does CAS (robbed bit) signaling do
the same?
 
Our recent tests indicated that CAS created about 7500-8000 interrupts for
15 spans CAS and one PRI.  that would be 24 X 15 or 360 channels, plus a PRI
with 23 channels.
 
The belief/specs were that the processor could handle about 12-14,000
interrupts per second, so 15 spans were fine, but we shouldn't go too far
past that.
 
Any comments on that?
