ne an assembly circuit, one must give a name to the proposed assembly, assign a status - proposed, active or inactive - and give a description of the assem- bly. In creating or modifying an assembly, one must define assembly endpoints and define internal assembly links. The ability to bulk load and automatically create the physical connectivity between network elements, frames and equipment adds to staff productivity at the Network Operations Centre (NOC). Assemblies will be available to network opera- tions staff as abstract capacity during the circuit design and provisioning process. Provisioning staff will be able to select the entry point to an assembly and have the system automatically assign/allocate capacity through the assembly. One must specify the parent connections for an assembly under consideration. The details of a parent connection typically comprise: sequence number for the parent connection appearance on the screen cross connection Table 10.1 Network inventory items. Category Action Assemblies Model an assembly of equipment, frames and physical connectivity Circuits Create circuits, modify existing circuits and query existing circuits Network elements Create, modify and query network elements and apply port templates Port templates Create port templates that can be selected to enter network element details Rings Create SDH rings that can be used to create path diversity in a network Reference screens Set up core network configuration details Reports Display and print specific network configuration information. 10 Network Inventory Management location of source network element type of source network element instance of source network element terminating card port name of the source and destination network elements and card identifiers - there may be more than one of each destination network element type of destination network element instance of destination network element. One must also specify path connections. Specifying a path connection involves the same type of information as for a parent co
