RE: (ASCEND) Quiescenting PRIs
Yes, I know the U.S. doesn't quite follow ITU. For ISDN, we follow the NI-2
spec on PRI's. NI-2 is defined by the North American ISDN Users Forum along
with BellCore. Again, what ANSI spec are you referring to? Where in the DMS
PRI spec is this referred to?
Please give me a citation.
