The MCB Office card supervises the feature authorization using the SAU (Software
Authorization Unit) lock device. The SAU is a small, encapsulated device that is
plugged into a connector on the left side of the MCB Office.
Figure 8-7
illustrates four
views of the SAU.
The SAU enables a set of permissions and feature authorizations associated with its
unique identification number. The Coral software detects and verifies the permission
settings of the SAU on the control card (MCB Office), enabling the system to function
properly.
The SAU provides the system identification number (i.e. a serial number). Each
system identification number is unique. In addition, the SAU stores a market
identification number, which indicates the general geographical area in which the
Coral system is installed. The system identification number is used to identify a
particular Coral system installation site.
During software installation, the SAU serial number is compared with the features
authorization data, to verify the authorized use of enhanced Coral system features.
During regular system operation, the SAU is checked to ensure that it remains attached
to the MCB Office card. However, if necessary, the SAU can be removed for short
periods (a maximum of two weeks) without interrupting system operation. If the SAU
is removed for more than two weeks, the system ceases to process calls.
Replacing an MCB Office card necessitates removing the SAU from the old card and
installing it onto the replaced MCB Office card.

The Coral system automatically ceases call processing after 14 days for any of the
following reasons:
„
The SAU serial number does not match the corresponding IMC8 SAU serial number.
„
The Coral generic version contained in the IMC8 is higher than is authorized by the SAU.
„
An SAU device is removed from the MCB Office front panel.
Relevant system messages appear on the PI, warning that the system will not operate
without the proper SAU.
