PortMaker®II AAL5 SAR
AAL5 SAR Firmware for TSP2
Description
PortMakerII firmware provides proven, reliable, and fully supported binary applications for the CX27470 Traffic Stream Processor. The ATM Adaptation Layer 5 (AAL5) application provides a bi-directional OC-12 throughput ITU I.363.5 SAR, traffic shaping, and a rich feature set. The firmware is also available with a source code license to allow customization and product differentiation.
The PortMakerII AAL5 firmware application complies with the ITU I.363.5 standard, and also conforms to the ATM Forum PICS Proforma for the AAL Type 5 tests. The firmware provides OC-12 throughput with 16K connections in bi-directional mode. It can also be configured in a uni-directional configuration (i.e., two chip solution) with 2xOC-12 throughput and 32K connections. ATM cell traffic uses the Utopia interface on the CX27470, while packet traffic can use either the Utopia/POS interface for streaming mode operation, or the PCI bus for shared memory operation. Host based management of the SAR is accomplished via the PCI bus using commands, acknowledgements, indications, and alarms.
