Indeed, capacity is critical to inventory in any context. Therefore, an inventory management OSS system should make it easy to determine the capacity of circuits. Details of network inventory are dependent upon network configuration - for example, the parent/child hierarchy of circuits - and are central to service provi- sioning. The availability of network inventory, such as circuit capacity, affects how network resources are to be provisioned to enable a service. Network inventory overlaps with network configuration particularly for logical network resources, as opposed to physical resources, since the logical structure of a network is mostly coincident with what is configurable.

Although inventory management OSS applications do account for asset location, if only by providing a text field in which to enter it, the issue of how the location is discovered is sometimes not mentioned. The answer is often prosaic: field staff must go and find the locatio
