I'm particularly interested in knowning if a PM3 can mix PRI and CT1, served
from the same switch, on a single chassis? I'd like to be able to mix
64K ISDN and analog callers on one box, without having to order both circuits
as PRI- the CT1-vs-PRI recurring cost is considerably different!
Livingston has said that on the dual-T1 PM3, both circuits need to be
served from the same telco central office because problems will occur if
the clocks on the two circuits are not in sync. But I have read here that
people have successfully used a dual-T1 PM3 with circuits from two distinct
telephone _companies_.
What's the real story?
