[Asterisk-Users] ZAP bchan and dchan HELP!!

[Kyle Hagan]

 We have install a DS3 with 28 DS1's we have an Adtran MUX breaking out 
the DS1's, we are trying to setup the system with 2 dchannels for each 4 
DS1's.

Everything looks fine when modprobe zaptel and wct4xxp and ztcfg -vvvvvv
but when I asterisk asterisk it says:

Aug 10 16:33:32 ERROR[8954]: chan_zap.c:6750 mkintf: Channel 24 is 
reserved for D-channel.
Aug 10 16:33:32 ERROR[8954]: chan_zap.c:9990 setup_zap: Unable to 
register channel '1-190'
Aug 10 16:33:32 WARNING[8954]: loader.c:403 __load_resource: 
chan_zap.so: load_module failed, returning -1

Do I HAVE to have a dchannel on every DS1? They want an extra $100 per 
dchannel.

PLEASE HELP.

I can have set the cards as follows:

zaptel.conf:
span=1,1,0,esf,b8zs
span=2,0,0,esf,b8zs
span=3,0,0,esf,b8zs
span=4,0,0,esf,b8zs
span=5,0,0,esf,b8zs
span=6,0,0,esf,b8zs
span=7,0,0,esf,b8zs
span=8,0,0,esf,b8zs
bchan=1-190
dchan=191
dchan=192
loadzone = us
defaultzone=us

zapata.conf:

 switchtype = 5ess
 signalling = pri_cpe
group = 2
 context=internal
