If the echo still exists, set the 

EC

 

Configuration:

 field to 2, 3, or 4, then test the voice 

quality. These settings provide help for the following scenarios:

Setting 2 – Minimizes speech clipping, but it takes a fraction of a second longer for the 
echo to fade.

Setting 3 – Eliminates speech clipping, but a strong echo may take 2 or 3 seconds to fade.

Setting 4 – 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.

If the echo still exists after trying every previous setting, contact technical support.

Telecommunications Service (WATS) trunk connects to 1 port of either an 8-port TN747B or to 1 of 
several CO trunk circuit packs.

pack is required).
