Before the change, the following configuration would be generated for a
span (in this case: channel for span 1)

cas=1-15,17-32,1101
dchan=16

That second line was added later on as I noticed that without it some
things break (things to do with the 16-th time slot. I'll try to figure
them out later).

Could you please elaborate on the bug DAHDI-763 ?
