5.On the DS1 Circuit Pack screen, set the Echo Cancellation? field to y.

When set to y, 2 new fields display: EC Direction: and EC Configuration:.

If you know the echo is coming into the Avaya CMC1 Media Gateway, keep the default setting for the EC Direction: field of inward.

If you know that the distant party is hearing echo that originates in the Avaya CMC1 Media Gateway or its line side stations or equipment, set the EC Direction: field to outward.

Keep the default setting for the EC Configuration: field of 4. This setting minimizes extremely strong echo, very hot signals, or excessive clipping or breakup of speech from a distant party. It reduces speech clipping but may allow slight residual echo or more background noise.

6.Test the voice quality on a telephone connected through the TN464HP or TN2464CP circuit packs and known to have echo to see if the echo was eliminated.
