Use the CG 6565E daughterboard with an echo chip to provide echo cancellation capabilities. If you are installing a CG 6565E board without an attached daughterboard, you can use DSP resources to provide software echo cancellation capabilities.
The following table provides the filter length, adaptation times, and MIPS consumption for software echo cancellation DPFs. Filter length represents the maximum echo delay that can be handled by the software echo canceler.
Note: MIPS in parentheses are best case scenarios. These numbers are guaranteed for the first four instances of echo per DSP core.
