Distributed call and connection management (DCM) based on PNNI SERIES G: TRANSMISSION SYSTEMS AND MEDIA DIGITAL SYSTEMS AND NETWORKS Digital terminal equipments Operations administration and maintenance features of transmission equipment Study Group 15; A
This Recommendation provides the protocol specifications for distributed call and connection management based on PNNI/Q.2931, developed within the context of G.7713/Y.1704 DCM requirements. The protocol specifications in this Recommendation specify the communications across interfaces to effect automated call operations and connection operations. This version of the Recommendation is concerned with the specification for soft permanent connections. As such the call model is based on the concept of a null call as described in ITU-T Rec. G.8080/Y.1304. By providing a call identifier in the soft permanent connection model, the specification can be extended in later versions to include switched connections. As such, name translation/directory services and call capability sets are not included.
