Cisco Cisco IOS Software Release 12.4(2)XB6

This document describes the asymmetric digital subscriber line (ADSL) 2/2+ Annex M (product name: 
HWIC-1ADSL-M) feature in Cisco IOS Release 12.4(11)XJ. This feature provides enhanced 
functionality by increasing upstream data rates. 

The Routed Bridge Encapsulation (RBE) over the Virtual Circuit (VC) Bundle feature is an existing 
feature, previously available on the Cisco IOS 12.4 (4)T release, that is now implemented on the 
Cisco 800 through 3800 platforms with the Cisco IOS 12.4(11)XJ release. 

Two additional software features in this release are impulse noise protection (INP) and an enhancement 
to the DSL enable-training-log command. INP reduces the number of errors caused by impulse noise. 
No configuration is needed for the improved INP. The DSL enable-training-log command has been 
enhanced with an option to specify when to capture a log file. This allows the command to log the 
firmware debug messages.
