ServiceSAR Controller

RS8234

Full-Featured ATM xBR Service Segmentation

and Reassembly Controller (ServiceSAR)

Conexant鈥檚 RS8234 accelerates service interworking by

emphasizing performance under worst-case short packet

conditions. In addition, the PCI host interface is one of the

most efficient in the industry in terms of bus occupancy.

The RS8234 not only meets the stringent requirements of

T.M. 4.1, but also enables advanced traffic control functions

such as GFR, CBR tunneling and virtual path shaping.

The RS8234鈥檚 service-specific features allow system designers

to accelerate specific protocol interworking functions for

applications like IP over ATM, Frame Relay or LAN emulation.

The device鈥檚 unique architecture enables advanced network-

level functionality and topologies. A few examples of these

features include echo suppression of multicast data frames on

ELAN channels, and peak cell rate (PCR) control established

per VCC, per tunnel, and/or per scheduling priority.
