CCS or hundred call seconds
A unit of c all traffic . Call traffic  for a fac ility is scanned  every 100 second s. If the fac ility is b usy, it is 
assumed  to have b een busy for the entire sc an interval. There are 3600 sec ond s p er hour. The 
Roman numeral for 100 is the c ap ital letter C. The ab b reviation for c all seconds is CS. Therefore, 
100 call sec ond s is ab b reviated  CCS. If a fac ility is b usy for an entire hour, then it is said to have 
been busy for 36 CCS. See also 
Er la n g.
capability
A req uest or indic ation of an operation. For example, Third  Party Make Call is a req uest for setting 
up  a c all; event rep ort is an indic ation that an event has occ urred .
capability group
Set of c ap ab ilities, determined  by switch ad ministration, that c an b e requested b y an ap p lication. 
Cap ab ility g roup s denote assoc iation typ es. For examp le, Call Control is a typ e of assoc iation that 
allows certain func tions (the ones in the cap ab ility g roup) to be p erformed  over this typ e of 
assoc iation. Also referred to as ad ministration group s or ap p lic ation servic e elements (ASEs). 
CA-TSC
Call-Assoc iated Temp orary Sig naling  Connection
cause value
A value is returned in resp onse to req uests or in event rep orts when a d enial or unexp ected  
condition oc c urs. ASAI cause values fall into two c od ing  standards: Cod ing  Standard 0 inc lud es 
any c ause values that are p art of AT&T and  CCITT ISDN spec ifications; Coding stand ard  3 
inc lud es any other ASAI c ause values. This d ocument uses a notation for c ause value where the 
cod ing  stand ard  for the c ause is g iven first, then a slash, then the c ause value. Example: CS0/100 
is cod ing  stand ard  0, c ause value 100.

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
