Cisco Cisco Catalyst 6000 Multilayer Switch Feature Card MSFC2

The Lossless Compression R1, ATM Cell Switching, and External BITS Clocking Source features 
introduce a new compression technique in DSP firmware and add enhancements to Cisco IOS that 
include cell switching on ATM segmentation and reassembly (SAR), and the use of an external BITS 
clocking source. These features enable Cisco multiservice routers to be used to transparently groom and 
compress traffic in a wireless service provider network and enable a service provider to optimize the 
bandwidth used to backhaul the traffic from a cell site to the mobile central office for more efficient use 
of existing T1 and E1 lines.
