Next, the source and destination of the parent connection must be defined. This involves defining, for each end, the location, type, instance (given by an index number) and the terminating card port name of the network element. Path connections are also given for any selected assembly and these are detailed in the same way as the parent connections. The assembly editing screen is given in Figure 11.28. The circuit query screen is given in Figure 11.29. OSS for Telecom Networks Circuits can be queried by service ID for any service that the circuit supports, cir- cuit name, customers which the circuit services, any services that are affected by - or are dependent upon - the circuit, bearers, NE and/or location. To narrow a search for circuits, additional criteria that can be specified such as the status of the circuit proposed, reviewed, confirmed, whether the circuit has been commissioned - which would mean that the circuit is "in service", bearers for the circuit, and alarms that are affecting the displayed circuit. A circuit query will return the name of the cir- cuit, bearers on the circuit, the circuit's tributary number - if it is a tributary, the customer to which the circuit provides service, the service identification of the cir- cuit, the status of the circuit and, finally, whether or not the circuit has recently been affected by an alarm. Circuit capacity details the spare bearer capacity, and spare configured ports can be searched. The cards and slots, parent ports and child ports can be viewed for each spare configured port for any given circuit. The circuit capacity screen pro- vides the following information: circuit na
