I did think of that but my fingers totally forgot to put it in the email. ;) I shall assume it is either really hard or really easy to change this. > > If that was done, there wouldn't actually be any changes required in > chan_dahdi.conf at all; if you wished to, you could put in a comment for > each 32nd channel to indicate that you are intentionally skipping it, > but there is no need to make chan_dahdi actually aware of that channel > at all. This is where my query lives... What if... Imagine 2+ E1s sharing the first E1's D-channel for timing and some manufacturer thought about selling some hardware that would allow the use of 32 channels on the next E1 and so on. So something like "dchan=16 bchan=1-15,17-31,32-63" could happen. How would the current DAHDI act if B-Channels existed at channel 32. Does it just skip them _because_ it is an E1 or does it see the channel and skip it. My apologies, its a holiday here and I am catching up with my email. This topic was in my email. > > -- > Kevin P.
