Chapter 3: Configuration
First Example: Channel Bank
The Channel Bank in this example has 24 FXS ports. In this
configuration, the system.conf is set for the card to provide timing to the
channel bank and fxoks is set for 24 stations.
Set
chan_dahdi.conf to mirror the configuration with signalling =
fxo_ks
and define it for channels 1-24.
/etc/dahdi/system.conf:
loadzone = us
defaultzone = us
span = 1,0,0,esf,b8zs
fxoks = 1-24
echocanceller = mg2,1-24
/etc/asterisk/chan_dahdi.conf:
group = 1
echocancel = yes
context = channelbank
signalling = fxo_ks
channel = 1-24
