[asterisk-users] PRI - DS3 Calls Dropped

[Alex Balashov]

I think one critical aspect to explore here is, what exactly is meant by 
"drop the DS3 service to redundant back-ups"?

SONET protection switching inside their transport core should not impact 
your DS3s or voice-bearing T1s if it is within the 50 ms tolerance of
the standard.  I imagine some SONET line equipment even jitter-buffers
to account for this sort of thing, although that is speculation.

Or is there another form of "back-up" involved?  What is it?
