CN8236

OC-3 ATM SAR Controller with UTOPIA Level 2

Overview

Description

Mindspeed's CN8236 Service Segmentation and Reassembly (ServiceSAR) controller integrates ATM terminal functions, PCI bus master and slave controllers, and a UTOPIA 1 or 2 interface with service-specific functions in a single package for AAL0, AAL3/4 and AAL5 operations. The CN8236 controller generates and terminates ATM traffic (TM 4.1) and automatically schedules cells for transmission with patented xBR traffic management. The CN8236's service-specific features allow system designers to accelerate specific protocol interworking functions for applications like IP over ATM, frame relay or LAN Emulation.
