A generic operations system interface to support the next generation of digital loop carrier systems

摘要

The application of a generic interface between operations systems and microprocessor controlled network elements (OS/NE) to both universal and integrated DLC (digital loop carrier) systems is discussed. The high-level components of a DLC system are defined, and a generic interface between operations systems and their central office terminal of a microprocessor-controlled DLC system is described. The adaptation of the generic operations-systems interface to the DLC system for use with a generic interface between the local switching system and the remote digital terminal of an integrated DLC system is explored. Some issues associated with integrating a DLC system into a switching system are presented.
