Integrated Services Digital Network (ISDN)
A pub lic  or p rivate network that p rovid es end -to-end  d ig ital c ommunic ations for all servic es to 
whic h users have ac cess by a limited  set of stand ard  multip urp ose user-network interfaces 
d efined  b y the CCITT. Throug h internationally ac c ep ted stand ard  interfac es, ISDN p rovid es dig ital 
circuit-switc hed  or pac ket-switc hed  c ommunic ations within the network and links to other ISDNs to 
p rovid e national and  international d igital c ommunic ations. See also 
Integ rated  Servic es Digital 
Network Basic  Rate Interfac e (ISDN-BRI) and Integ rated Servic es Dig ital Network 
Primary Rate Interfac e (ISDN-PRI).
Integrated Services Digital Network Basic Rate Interface (ISDN-BRI)
The interfac e b etween a communications system and  terminal that inc lud es two 64-kb ps 
B-channels for transmitting  voic e or d ata and  one 16-kb ps D-channel for transmitting assoc iated  
B-channel c all c ontrol and  out-of-b and  sig naling  information. ISDN-BRI also inc lud es 48 kbp s for 
transmitting  framing  and D-c hannel c ontention information, for a total interface sp eed  of 192 kb p s. 
ISDN-BRI serves ISDN terminals and  d igital terminals fitted  with ISDN terminal ad ap ters. See also 
Integ rated  Servic es Dig ital Network (ISDN) andInteg rated  Servic es Dig ital Network 
Primary Rate Interfac e (ISDN-PRI).
Integrated Services Digital Network Primary Rate Interface (ISDN-PRI)
The interfac e b etween multip le c ommunic ations systems that in North America inc lud es 24 
64-kb p s c hannels, correspond ing  to the North Americ an d igital sig nal level-1 (DS1) standard rate 
of 1.544 Mbp s. The most c ommon arrang ement of channels in ISDN-PRI is 23 64-kbp s B-channels 
for transmitting  voic e and  d ata and  1 64-kb p s D-channel for transmitting  assoc iated B-c hannel call 
control and  out-of-band sig naling  information. With nonfac ility-assoc iated  sig naling  (NFAS), 
ISDN-PRI can include 24 B-c hannels and  no D-channel. See also

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

other fac ilities that share the D-c hannel are c onfigured  without D-channels. If D-channel b ackup is
