4532 PMC ATM Over OC-3/STM-1
Communications Controller is designed for carrier-
class telecommunication networks supporting
the most demanding ATM applications including
broadband Internet access, second and third
generation wireless, ‘converged’ next generation
networks (i.e. softswitch environments), and
integrated voice and data over carrier and
enterprise ATM backbones. Its support for ATM
to Ethernet interworking capability provides
telco system OEMs with a gateway-on-a-card
solution for bridging dissimilar technologies. This
capability allows carriers to cost-effectively migrate
existing communications infrastructure to newer
technologies and enables future-proofi ng of new
equipment deployments.
This ready-to-use, intelligent OC-3/STM-1 ATM line
interface is fully standards-compliant and features
software development tools to facilitate immediate
integration into CompactPCI
®
, VME, or custom
telecommunications platforms. In addition, the 4532
allows direct connection to SONET or SDH facilities,
eliminating the need for additional line termination
equipment. Featuring a powerful MPC8260A
on-board RISC processor, high performance
architecture, and advanced ATM functionality, the
4532 is the industry’s best choice for a 155 Mbps
PMC I/O solution in high-availability servers driving
next-generation wireless, convergence, and
broadband access telecom applications.
