    FireStream50 ATM PCI SAR Controller

    FireStream 50 block diagram The FireStream50 is a low cost ATM protocol controller which autonomously terminates ATM Adaptation Layer standard Type 5 (AAL5). ATM cells are received through a UTOPIA v2.01 compliant interface. Simultaneous segmentation and reassembly can be achieved at an average rate in excess of 52Mbps.
    The device contains embedded memory to support 32 virtual circuits (VCs).
    All ATM Forum traffic classes (ABR, VBR, CBR, UBR) are supported with traffic management to ATM Forum TM4.0 specification for all 32 VCs.
    The FireStream50 is suited to many ATM applications including ATM switches, home gateways, integrated access devices, set-top boxes, routers and adaptor cards.
