I am generally aware of the state of ISDN deployment in Asia, but I am often asked how that compares with the status of ISDN in the United States. Japan, for example, has had active Basic Rate Access (BRA) service [INS NET-64] available for over a year now. And although the requests for this service were lower than orginal forecasts, NTT has begun service of its Primary Rate Access (PRA) service [INS NET-1500] and is continuing to expand the service areas of BRA. My question is what is the status of ISDN deployment in the US? Is is past the field trial stage and generally available to commercial subscribers? or much more limited in geographic availability? Also, with SS7 not yet widely implemented combined with the fragmentation produced by a multitude of non-centrally administered RBOC's, does the user community prefer to 'roll there own' network (using fractional T-1 for example) instead of waiting for ISDN?
