Modelware offers two modular products for AAL 5: Foundation and Manager. The AAL 5 Foundation core implements the Common Part of the AAL type 5, including the CPCS and the SAR in Streaming Mode. In addition, the AAL 5 Foundation core performs ATM header insertion and extraction, which are ATM Layer functions. The AAL 5 Manager core includes the Foundation core and the memory management functions needed to support the AAL 5 Message Mode. On the Service Access Point (SAP) side, both AAL 5 cores interface to the user's circuitry through an easy to use packet interface. On the ATM side, the cores interface to an ATM switch through a UTOPIA interface.
