users by p erforming  switc hing  and  sig naling  operations. See also

A feature that enab les internal c allers, up on reaching  a b usy extension, to have the system 
automatic ally connec t and ring  b oth parties when the c alled p arty b ec omes available.
Automatic Call Distribution (ACD)
A feature that answers calls, and then, d ep end ing  on ad ministered instruc tions, delivers 
messag es app rop riate for the caller and  routes the c all to an agent when one b ec omes available.
Automatic Call Distribution (ACD) split
A method of routing c alls of a similar typ e among ag ents in a call c enter. Also, a group  of 
extensions that are staffed  b y ag ents trained to hand le a certain typ e of inc oming  c all.
Automatic calling unit (ACU)
A devic e that p lac es a telephone call.

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

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.
