N+1
Method  of d etermining  redundant b ackup req uirements. Examp le: if four rectifier modules are 
req uired  for a DC-powered  sing le-c arrier c ab inet, a fifth rec tifier mod ule is installed for b ackup.
N x DS0
N x DS0, equivalently referred  to as N x 64 kb ps, is an emerg ing  stand ard  for wid eb and  calls 
sep arate from H0, H11, and  H12 ISDN c hannels. The emerg ing  N x DS0 ISDN multirate c ircuit 
mod e b earer servic e will p rovid e c irc uit-switc hed  c alls with d ata-rate multip les of 64 kb p s up to 
1536 kb p s on a T1 facility or up  to 1920 kb p s on an E1 fac ility. In the switc h, N x DS0 channels will 
rang e up  to 1984 kbp s using NFAS E1 interfac es.
NANP

narrowband
A c ircuit-switc hed  c all at a d ata rate up  to and  inc lud ing  64 kb ps. All nonwid eb and  switc h calls are 
consid ered  narrowband.
native terminal support
A p red efined  terminal typ e exists in switc h software, eliminating  the need to alias the terminal (that 
is, manually map  call app earances and  feature buttons onto some other natively sup p orted  
terminal type).

Nonfacility-associated signaling (NFAS)
A method that allows multip le T1 and /or E1 fac ilities to share a sing le D-c hannel to form an 
ISDN-PRI. If D-c hannel b ackup is not used, one fac ility is config ured  with a D-c hannel, and  the 
other fac ilities that share the D-c hannel are c onfigured  without D-channels. If D-channel b ackup is 
used , two facilities are c onfigured  to have D-c hannels (one D-c hannel on each fac ility), and  the 
other facilities that share the D-c hannels are config ured without D-c hannels.
