## ASB 150 02 Hardware key based licensing

### General

The access to the different ASB 150 02 features is defined by a hardware key based licensing concept. The hardware named FECU (Feature Enabling Circuit Unit) is connected to the CPU-D4.

The features are basically defined into Basic, Networking and CTI features, which results into 10 different FECU Indexes for Release 9 - Release 12 and into 11 different FECU Indexes for Release 13. Together with Release 14 the hardware key based licensing was replaced by the ASB 150 02 Software key based licensing.

For all the article numbers as well as a detailed feature/FECU matrix see document document Facility description General, 15534-ASB150 02 Uen.

### New license

According to the customer’s ordered features the dedicated FECU will be delivered.

Note

It is a must that the FECU is connected to the CPU-D4 otherwise the all features which are requiring a FECU will not work although they might be correctly programmed. If the CPU-D4 is operating without connected FECU, the feature level will automatically be reduced to Release 8.

### Upgrade of an existing license to a higher index

Simply exchange the existing FECU with one of a higher Index. Return the remaining FECU (except FECUs with Index 1) back to Ericsson in order to get the former price refunded.

### Update an existing license to a one of a higher release

Simply exchange the existing FECU with one of a article number series. Return the remaining FECU (except FECUs with Index 1) back to Ericsson in order to get the former price refunded.
