BICC Overview

Description: OpenSS7 SS7 Stack Overview.

This is the Siganlling System No. 7 (SS7) Bearer Independent Call Control (BICC) component of the OpenSS7 stack. This component implements BICC functions in a STREAMS multiplexing driver.

Originally it was believed that the ISUP component (and thus the BICC component) would be more properly placed in user-space; however, the current implementation approach for ISUP and ISDN places the entire ISUP and ISDN call control and signalling functions in a STREAMS multiplexing driver.

The BICC component has not been started, but the current design approach is to provide BICC modifications to the ISUP component to implement BICC within the ISUP component.

The BICC STREAMS driver will support I_LINK and I_PLINK of Message Transfer Part Interface (MTPI) streams providing SS7 MTP-SAPs under the multiplexing driver.
