Figure 2: IMU, Relay and Gateway work flow
Gateways and relays will move from the depot to their pole locations. Gateways and relays are installed and tested
using the Field Maintenance and Diagnosis tool. Once gateways and relays have been installed, the IMUs move from
the depot to customer sites, where they are installed, tested and their installation in the gateways verified using the
Field Service Application tool. At some point in their lives IMUs, relays or gateways may be replaced due to
suspected failure or other reasons. These units go back to the depot. Suspected failures may be explored using the
Field Maintenance and Diagnosis tool. While both the depot commissioning tools and the network configuration
manager modify the network configuration database, the depot commissioning tool is limited to filling in id (e.g., IMU
utility serial number) and address fields (e.g., WAN addresses) for units that have already been entered into the
network configuration database. This implies that a unit must have already been added into the system by the network
configuration manager before the depot commissioning tool can be used to modify its data, and that a null entry for
certain fields must be allowed in the network configuration database for IMUs, relays and gateways that are marked as
not installed.
Derived Requirements
Derived requirements are those that are driven by the primary requirements, but are imposed on ourselves.
Supported Applications
For those applications whose user interfaces are implemented using Java applets, designers/implementers should strive
to keep the applets small, and implement any heavy duty operations in the servers rather than in the applets
themselves.
Supported Interactive Applications
Interactive applications are those whose functions are primarily driven by an explicit user request, such as a meter
read or a request to upload a database from a field service application. The Innovatec utility server system
implements services for the following user visible applications. These “applications” are not necessarily implemented
as monolithic applications in the traditional sense, but they appear that way to end-users.
