Cisco Cisco MGX-FRSM-HS2 B Serial Frame Service Module

The SM-X-1T3/E3 enhanced service module provides high-speed performance for advanced, fully 
converged networks supporting a wide array of applications and services such as security and advanced 
QoS for voice and video. T3/E3 and subrate T3/E3 connectivity optimizes WAN bandwidth for 
deploying new applications and service delivery. All supported platforms are capable of supporting full 
line rate performance but impose varying levels of CPU overhead and therefore affect the overall 
platform performance. See 

 for recommended branch office positioning.

Your software release may not support all the features documented in this module. For the latest feature 
information and caveats, see the release notes for your platform and software release. Use Cisco Feature
