Nonfacility-associated signaling (NFAS)
A method that allows multiple T1 and/or E1 facilities to share a single D-channel to form an ISDN-PRI. If 
D-channel backup is not used, one facility is configured with a D-channel, and the other facilities that share 
the D-channel are configured without D-channels. If D-channel backup is used, two facilities are configured 
to have D-channels...
