NFAS is the setup whereby one D channel (note: not B channel) carries the call signalling for more than on PRI span. Each B channel carries an individual call, a D channel carries the call control information for the B channels on the span (or multiple spans in the case of NFAS).
And if the span with that D channel goes down, good night. :)
We don't use NFAS here because of the hassle in coordinating which spans have the D channels (and backup D channels) with the telco. The extra B channels that you get from running NFAS aren't worth the hassle as far as I'm concerned. :)
Ditto. More wacky 3Com code to troubleshoot, more coordination with the telco on something they may or may not understand, and less reliability. Charles
