Ever since the early days of the Multiband (IMUX product) this question
has come up. The bottom line is that it *should* work in most cases.
The MAX will take clocking from the first T1 interface that you have
configured as "clock source = yes". It will sync to that clock, and
all transmit clocks will be synchronized to it. The potential catch-22
is when the T1s come from different sources *AND* those sources are
not synchronized (trace back to a stratum-1 clock source).
As you will read from many others on this list, they have this working
just fine - many different combinations of PRI/CT-1 and different
carriers. The one gotcha is that we *have* seen odd cases where the
clocking was not synchronized close enough and frame-slips can
occur. The only way I know to find out is to try it.
