Introduction of YD/T 1620.4-2007

SDH-based MSTP network management technical specification - Part 4: EMS-NMS interface common information model 1 Scope This part specifies the EMS-NMS interface common information model of the SDH-based MSTP transport network, which is independent of implementation technology. This part is applicable to the EMS-NMS interface of the SDH-based MSTP transport network. This part is not applicable to the management of WDM optical network and PDH system. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part.
