Typ e of b ac kup  used  with Non-Fac ility Assoc iated  Sig naling  (NFAS). A p rimary D-c hannel 
p rovid es sig naling  for an NFAS D-channel g roup  (two or more PRI fac ilities). A sec ond  D-c hannel, 
on a sep arate PRI facility of the NFAS D-channel g roup , is d esig nated  as b ackup  for the 
D-channel. Failure of the p rimary D-c hannel causes automatic  transfer of call-c ontrol signaling to 
the bac kup  D-c hannel. The b ackup  b ec omes the p rimary D-c hannel. When the failed c hannel 
returns to servic e, it b ecomes the b ackup  D-c hannel.
