In about a year and a half of service with BellSouth we have had only two outages totalling less than 12 hours in total. one outage took out all digital service in our 20 story building and the other took out all ISDN in the Downtown Area. other than that we have never had any PRIs or T1s from BellSouth down. based on thier excellent service, we started with 2 standard PRIs (23B + 1 D each) then ultimately switched to 4 PRIs in an NFAS group (95 B + 1 D). (neither outage would have been prevented by having 4 B channels) Leon -----Original Message----- >I recall a discussion taking place here a while back about the pros and >cons of NFAS, backup D channels, etc., and I wanted to solicit some further >input on it. > >I need to put two PRIs into a TNT in a hunt group.
