Dahdi echo canceller(s)

I have the following dahdi channels:

# dahdi_cfg -vv
DAHDI Tools Version - 2.2.0

DAHDI Version: 2.2.0.2
Echo Canceller(s): 
Configuration
======================


Channel map:

Channel 01: FXO Kewlstart (Default) (Echo Canceler: none) (Slaves: 01)
Channel 04: FXS Kewlstart (Default) (Echo Canceler: none) (Slaves: 04)

2 channels to configure.

Setting echocan for channel 1 to none
Setting echocan for channel 4 to none

Where do I set the echocan for the channels?
Which echocan(s) can I set?

(I’m sure it’s written somewhere in the documentation, but I can’t find it.)
