CCS or hundred call seconds

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

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.
