 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.
