History Log

Product Description

CenturyLink's retail telecommunications service, Central Office - Automatic Call Distribution Service (CO-ACD), is available for resale by Competitive Local Exchange Carriers (CLECs) to their end-users. Additional information about resale of CenturyLink's retail services can be found in the Resale - General.

CO-ACD Service is a call distribution solution that provides the ability to manage and track incoming calls without investing in hardware. It provides an equal distribution of large call volumes to designated groups of answering positions, known as agent positions.

Calls terminating on a CO-ACD are placed in queue in the order of their arrival when an agent is not available to answer them and removed from queue as agents become available. Incoming calls are presented to the next available agent in order of arrival and priority. Queue slots are dedicated time slots used to hold incoming calls in a delayed state until an agent position becomes available.

CO-ACD can be provided as Basic CO-ACD or Deluxe CO-ACD. You may have more than one CO-ACD, but within a Customer Group, all positions must be either Basic or Deluxe. End-user subscribers on Basic CO-ACD Service receive 10% queuing based on the total number of CO-ACD service positions and Deluxe CO-ACD Service receive 30% queuing. CO-ACD group hierarchy is comprised of three groups:

  • Customer Group, (also known as System Group), is the highest group level. All ACD groups and sub-groups are divisions of the Customer Group which is a unique set of numbers for receiving incoming calls.
  • ACD Group is a division of the Customer Group. It identifies different groups of departments or supervisor groups within the Customer Group. There can be up to 255 ACD Groups within a Customer Group.
  • Sub-Group is a group within an ACD Group.

CO-ACD Service also provides ability to limit feature use:

  • Agent position - Used for answering ACD calls
  • Supervisor position - Used for monitoring agent position activity

CO - ACD is also available as a feature on Centrex Plus and Centron®, and Centrex Prime®.


CO - ACD is available in Arizona, Colorado, Idaho (Southern), Iowa, Minnesota, Nebraska, Oregon, Utah and Washington.

CO-ACD service is only available in DMS™-100 Central Offices capable of providing Basic, Deluxe and Enhanced optional service where facilities have been provisioned for the service.
