Enhanced ITU-T G.168 Echo Cancellation in 12.2(13)T

[mbell]

The release notes for this feature say "Not all Cisco platforms that use TI DSPs support the extended EC. All other platforms continue to use the Cisco proprietary 32-ms EC by default." How do I know whether the DSPs I have in a router will support the new feature? If I have DSPs that don't support it, how can I get some that do?

As per this, the (Cisco-proprietary G.165 EC is 8 ms)

Where did u find that it is 32ms?

Also I find that it is supported on all 7200 and 7500 platforms
