PortMaker-I-AAL5-SAR中文资料AAL5 SAR Firmware for TSP1数据手册MACOM规格书

描述 Description

***All products in this section are DISCONTINUED parts. This section is for SUPPORT ONLY***Contact SupportPortMakerI AAL5 firmware provides proven, reliable and fully supported binary applications for the MXT4400 Traffic Stream Processor. The ATM Adaptation Layer 5 (AAL5) application provides a uni-directional OC-12 throughput ITU I.363.5 SAR, traffic shaping and a rich set of other features. The PortMakerI 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 64K connections in uni-directional mode (i.e., two chip solution). It can also be configured in a bi-directional mode (i.e., one chip solu- tion) with 2xOC-3 throughput and 32K connections. ATM cell traffic uses the Utopia interface on the MXT4400, 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.
