6000 family of switches. The ATM PA-A3 is designed with a high-performance, dual segmentation and reassembly (SAR)
architecture with local buffer memory.
The PA-A3-OC12 family went End of Sale (EOS) on May 2005 and are no longer orderable.
The PA-A3-T3, PA-A3-E3, PA-OC3MM, PA-A3-OC3SML and PA-A3-OC3SMI will be End of Sale (EOS) on December 31,
2006 for all platforms supported. The PA-A3-8T1IMA and the PA-A3-8E1IMA are not affected by this end of sale
announcement. For more details on the mentioned EOS PA’s, please see the following bulletin:
http://www.cisco.com/en/US/prod/collateral/modules/ps2033/prod_end-of-life_notice0900aecd80224b94.html
The ATM PA-A3 supports advanced ATM hardware features listed in Table 1, such as per-virtual circuit (VC) and per-virtual path (VP) traffic
shaping, as well as support for most ATM service classes such as non-real-time Variable Bit Rate (nrt-VBR), Available Bit Rate (ABR) and
Unspecified Bit Rate (UBR), and support of 4096 ATM VCs.
