Figure SO.22a - Service and Resource Characteristic Associations

Service Features and Service Parameters are two other synonyms for a ServiceSpecCharacteristic, and are used in models from other TM Forum member companies.<br/>ServiceSpecCharacteristics and ServiceSpecCharacteristicValues capture the differentiating features of a particular Service. However, ServiceSpecCharacteristics are not versionable objects. This is because ServiceSpecCharacteristics do not add any information in and of themselves – rather, they are used to emphasize key features of a ServiceSpecification.<br/>There are cases when an instance of a ServiceSpecCharacteristic and/or a ServiceSpecCharacteristicValue must be translated to a corresponding ResourceSpecCharacteristic and/or a ResourceSpecCharacteristicValue. For example, there may be a ServiceSpecCharactertistic that represents the size of an email box as defined by associated 10MB instance of SerivceSpecCharacteristicValue. This value may be translated into the actual size of 10.5MB as defined by the ResourceSpecCharacteristicValue associated to an email box size ResourceSpecCharacteristic.<br/>The following Figure shows the associations between characteristics in the Service and Resource domains that enable this translation.<br/>
