The refurbished Cisco
PA-A3-OC3SML is an enhanced asynchronous
transfer mode (ATM) port adapters (ATM PA-A3) are single-port, single and
dual-wide ATM port adapters for the Cisco 7200, 7500 and 7600 OSR series
routers using the FlexWAN module for the Catalyst� 6000 family of
switches. The ATM PA-A3 is designed with ahigh-performance,
dual segmentation and reassembly (SAR) architecture with local buffer
memory. The ATM PA-A3 supports advanced ATM hardware features 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
VariableBit Rate (nrt-VBR), Available
Bit Rate (ABR) and Unspecified Bit Rate (UBR), and support of 4096 ATM
VCs.
