  Erlang  is  untyped.  It  has  {pattern  matching}  syntax, 
  {recursion  equations},  explicit  {concurrency},  {asynchronous 
  message  passing}  and  is  relatively  free  from  {side-effects}. 
  It  supports  transparent  cross-{platform}  distribution.  It  has 
  primitives  for  detecting  run-time  errors,  real-time  {garbage 
  collection},  {modules},  {dynamic  code  replacement}  (change 
  code  in  a  continuously  running  real-time  system)  and  a 
  {foreign  language  interface}. 
 
  An  unsupported  free  version  is  available  (subject  to  a 
  non-commercial  licence).  Commercial  versions  with  support  are 
  available  from  {Erlang  Systems  AB}.  An  {interpreter}  in 
  {SICStus  Prolog}  and  compilers  in  {C}  and  Erlang  are  available 
  for  several  {Unix}  {platforms}. 
 
  {OTP}  is  an  associated  control  system  platform.

  3.    36  {CCS}  per  hour,  or  1  call-second  per  second 
 
  Erlang  is  a  unit  without  dimension,  accepted  internationally 
  for  measuring  the  traffic  intensity.  This  unit  is  defined  as 
  the  aggregate  of  continuous  occupation  of  a  channel  for  one 
  hour  (3600  seconds).  An  intensity  of  one  Erlang  means  the 
  channel  is  continuously  occupied.
