Conforms to common switch interface (CSIX) specification CSIX-L1 1.0
Supports UTOPIA and packet over SONET (POS) interfaces on the traffic manager side and synchronous interfaces on the fabric side
Includes user data and flow control channels
Optimized for AlteraÃƒâ€šÃ‚Â® APEXÃƒÂ¢Ã¢â‚¬Å¾Ã‚Â¢ 20KC and APEX II architectures
The CSIX defines a physical interface for transferring information between a traffic manager (network processor) and a switching fabric. SOCmagic's CSIX interface core implements the transition from traditional interfaces to the CSIX interface.
The CSIX interface core consists of two components: traffic manager-to-CSIX, which is applied to the line card, and CSIX-to-fabric, which is applied to the fabric. The traffic manager-to-CSIX adapts the traffic manager interface (UTOPIA and POS) to the CSIX interface, and the CSIX-to-fabric adapts the CSIX interface to the fabric synchronous interface."
