If you haven't purchased the cards yet, I would suggest that at the
point you think you need 2 ports that you purchase the 4 port card. The
cost isn't that much more incrementally and then leaves you twice the
expansion in spare.

For configuring the cards, you just need to make a new span declaration.
and then configure the next 24 channels. For the signaling, you would
probably want to loopstart with disconnect supervision, in asterisk this
is listed as kewlstart. This will make sure that when you hang up the
line asterisk will know it.

Example would be -

zaptel.conf -

span=1,0,0,esf,b8zs
E&M=1-24
span-2,1,0,esf,b8zs
fxoks=1-24

zapata.conf

signalling=fxo_ks
context=blah
group=1
channel => 1-24


Then the channel bank would follow the same theory for the Line code and
framing?

-gcc
