This standard addresses the code and format structures for both circuit connections as well as facility connections. Both types of connections are depicted through seven application specific combinations of data unit representation (four format structures). The seven format structures are:

Message trunk circuits.

Message trunk groups.

Special services circuits. 

Cable facilities.

Cable facilities with pair identification.

Carrier facilities. 

Carrier facilities with channel/time slot identification. This standard is intended to support various intercompany processes for both humans and machines as it relates to business supporting functions. Some example applications include:

Planning, Forecasting, and Reporting.

Engineering and Inventory Management: Circuit/Design Layout Records (CLR/DLR). 

Ordering: Access/Local Service Request (ASR/LSR), Firm Order Confirmation (FOC).

Service Order/Work Order Processing.

Billing: Carrier Access (CABS).
